Chairman's Statement

On behalf of the Board, I am pleased to report on the performance and activities of the Company in 2023.

Simon Hogan Chairman

On behalf of the Board, I had hoped to report an improved share price this year. However, the share price remains at a steep discount, despite an increase in NAV in 2023, as is the case for many listed funds presently. The outlook for the clean hydrogen sector remains positive and we believe that the portfolio can generate attractive returns over time. We fully support the Investment Advisor's strategy of investing in a diversified portfolio of hydrogen assets, across the value chain. Whilst macro-economic factors are outside of our control, we believe that selective investment, stewardship of the portfolio, and divestments can positively impact our NAV, and improve the share price over time.

Hydrogen Industry Landscape

The outlook for the clean hydrogen sector remains positive, and industry investment and capacity growth is accelerating in a sector that plays a key role in the energy transition. The COP 28 meeting in Dubai at the end of 2023 concluded with a call to transition away from polluting fossil fuels and accelerate growth in renewables, in order to mitigate the impact of climate change. At the same time, government policies and funding in many regions remain supportive of growth in clean hydrogen, as part of the push to 'net zero'. The fundamentals of the hydrogen sector continue to strengthen, despite weak macro-economic conditions. The Investment Advisor has tracked a 50% increase in green hydrogen production in 2023 compared to 2022, and an over 400% increase in investment in the sector, underpinning further growth. All of this underscores my view that the outlook for investment in clean hydrogen remains positive, despite headwinds in markets more generally during 2023.

Share Price Discount

Whilst our share price traded at a premium to NAV in 2021 and early 2022, the weakness seen towards the end of 2022 has continued throughout 2023. We recognise that decline in our share price, which reflects wider moves in equity markets and the listed funds sector, will have been disappointing for our investors. Significant changes are underway in energy markets, with new industry and political emphasis on energy security as a result of Russia's invasion of Ukraine, with renewed market emphasis on fossil fuels.

Investors for the large part have allocated capital away from emerging technology sectors, as a result of higher market discount rates and reduced risk appetite, and this has impacted our share price. Factors, such as inflation, discount rates, energy policies and the weak funding environment also impact the underlying portfolio companies.

Nevertheless, I hope this Annual Report sets out the positive progress that we are making with value creation in the Company's portfolio, with businesses that we believe can generate substantial value for our investors over time.

The Company and the Investment Adviser continue to focus on increasing the share price and attracting fresh capital into the Company. The Company, in conjunction with portfolio companies, is planning to exit some positions during 2024, which the Board believes will support the Company's objective of delivering capital growth through investment in a diversified portfolio of hydrogen assets. Subject to wider market conditions, strong NAV performance over the long term may increase the Company's appeal to investors and underpin renewed share price performance.

Our business model remains to invest in growth companies in the hydrogen sector, with the aim to exit these positions over 3 to 5 years holding periods, at multiples of invested capital, in order to generate 10-15% NAV growth over time. While we are unable to influence the general market weakness around us, we continue to ensure that the Company is positioned to weather the current downturn and able to exploit growth opportunities when the market recovers.

Performance

The Company remains well positioned to grow value for our investors. During the period, the Company's NAV increased by 5.8%, from £125.4m to £132.7m (97.3 pence per share to 103.0 pence per share) due to valuation uplifts in multiple portfolio companies, as those management teams delivered on their respective growth plans. Our diversified approach to portfolio construction has contributed to a resilient valuation in 2023, despite weakness in financial markets more generally. Overall, private investments contributed £14.0 million or 10.8 pence per share to the valuation. This NAV growth was delivered despite the negative impact on valuations as a result of a prudent increase in discount rates, which had the effect of removing £8.6 million, or some 6.7 pence per share from our 31 December 2023 valuation, compared to 31 December 2022.

The Company reported a gain after tax of £7.3m for the period, equal to 5.7 pence per share. The Company's dividend policy is to only pay dividends in order to satisfy the ongoing requirements under the Investment Trust (Approved Company) (Tax) Regulations 2011. The Company has paid no dividends during the period, as we continue to focus on growth investments.

Eight of the Company's private investments are revenue generating, producing equipment and technology solutions for clean hydrogen production. The aggregate revenue from these investments was £74m in the 12-month period to 31 December 2023, an increase of 125% from the prior year. This growth is as a result of portfolio companies converting their distinctive technologies into orders from customers.

Investment Strategy and Update

The Company continues to invest in a diversified portfolio of hydrogen related activities, predominantly in private companies and with a particular focus on the innovative technologies that are needed to unlock profits in clean hydrogen. Wherever possible, we have sought to protect the Company from dilution of its interests, should we not be able to participate in funding rounds.

With the majority of the Company's capital now deployed, our approach has focused on incremental investments in existing portfolio companies, with £10.6 million invested in 2023 backing these management teams to deliver their growth plans. This comprised:

· The Company invested £3.5 million in a follow-on investment in hydrogen flight innovator Cranfield Aerospace Solutions Ltd, alongside Safran Corporate Ventures and the Strategic Development Fund;

· The Company committed to invest £2.5 million (EUR 2.8 million) into a green hydrogen production project at Thierbach, in Germany, managed by HH2E AG, in order to further progress this project, ahead of a final investment decision. To date £1.9 million (EUR 2.1 million) has been drawn;

· The Company invested £2.5 million in a follow-on investment in NanoSUN, a hydrogen technology, transportation and distribution business;

· The Company invested £1.8 million in a follow-on investment into Sunfire AG, a leading electrolyzer developer and supplier;

· The Company invested £0.5 million in a follow-on investment in Strohm, a low carbon pipeline innovator in the Netherlands; and

· The Company invested £0.4 million in a follow- on investment in Gen2 Energy, a green hydrogen development company in Norway.

It was also pleasing to see new investment from industrial strategic players in HydrogenOne's portfolio, such as HD Hyundai's backing of Elcogen, and Cemex in HiiROC, further supporting the Company's investment case for these investments. These investors not only bring growth capital, but also new routes to market for these distinctive technologies.

Valuation

Listed funds continue to come under scrutiny from investors regarding the valuation of portfolios of private investments. The Company applies a consistent approach to portfolio valuation, centred on discounted cash flows, using the International Private Equity and Venture Capital Valuation 2022 ("IPEV") Guidelines. The weighted average discount rate at 31 December 2023 was 14.2%, compared to 13.0% at 31 December 2022, which reduced NAV by £8.6 million or 6.7 pence per share at 31 December 2023. The details of these valuations are set out later in the annual report. The valuations in this report have an implied forward multiple of 9.8 times 2025 expected revenues, which is in line with listed hydrogen sector multiples, and underscores the robust approach we are taking to valuations. The discount of the Company's private investments to the listed peer group has narrowed over 2023, due to weakness in listed hydrogen company share prices. Share prices in the listed markets are reflected in the valuation of the Company through listed assets in the portfolio.

The Board meets quarterly with the Company's Investment Adviser and holds regular meetings to review all of the Company's investment valuations. The Board also has regular contact with the Investment Adviser outside of formal Board meetings. I and other Board members attended the Company's Capital Markets Day in 2023, where we met some of our investors and analysts, and the management teams of all the private companies that we have invested in. The Investment Adviser has a dedicated investment team and has the right to be represented on all of the boards of the private company investments.

Environment, Social & Governance

Since our launch in 2021 the Company has invested in clean hydrogen assets which contribute to the energy transition and can lead to avoided GHG emissions. ESG principles are integrated across the investment process. Our commitment to positively contribute to climate change mitigation, whilst integrating core ESG principles into our decision making and ownership process, is at the core of everything that we do as a Company. The Company is classified as an Article 9 Fund, the highest classification under the SFDR regulation. We are a signatory of the PRI, a United Nations supported network of financial institutions that promote sustainable investments, and disclosed GHG information on the Carbon Disclosure Project ("CDP") for the first time in 2023. In collaboration with our portfolio companies, we will push forward with our sustainable investment objectives as we continue to deploy capital in low-carbon growth.

In addition to climate-positive impact, particular focus is placed on engagement to deliver effective boards and the encouragement of sustainable business practices. These, and other issues, are evaluated prior to any investment decision, and managed thereafter through close relationships with the Company's private company investments.

The Company's portfolio companies are supplying critical components, such as electrolyzers and fuel cells, as well as services such as transportation and storage of hydrogen, to clean hydrogen manufacturing projects and hydrogen end-users. All of this results in the replacement of fossil fuels such as diesel in the energy mix, and avoids greenhouse gas emissions, which have totalled 141,695 CO2e since our IPO in 2021, presenting clear growth opportunities for the broader sector.

We are tracking GHG emissions from portfolio companies, which totalled 99 tCO2e in 2023 (Scope 1 and 2) and are engaged with these management teams to reduce GHG intensity over time. The Investment Advisor is represented on the boards of all of the private investments and driving continuous improvement in ESG delivery more generally.

The Company is dedicated to further developing and progressing our ESG framework to achieve the highest reporting and performance levels. Alongside this Annual Report, we are publishing a separate Sustainability Report, that sets out our policy and track record in more detail.

Annual General Meeting

The Annual General Meeting will be held on 21 May 2024 at 12.00 noon at the Company's registered office, 6^th floor, 125 London Wall, London EC2Y 5AS, and we look forward to welcoming shareholders to the event in person.

The meeting will consider the formal business of the AGM, as set out in the Notice of the AGM, and thereafter the Investment Adviser will provide a presentation on the Company's portfolio.

Events After the Period End

In February 2024, the Company implemented a restructuring of NanoSUN, and re-launched the streamlined business, renamed as Swift Hydrogen Ltd ('Swift'), which the Company owns. The carrying value of NanoSUN at 31 December 2023 is £5.4 million, compared to £11.5 million at 31 December 2022.

In March 2024, Sunfire announced a funding round totalling more than EUR 500 million. The Company exercised its anti-dilution and conversion rights in this round for #0.3 million. The Board resolved to make a non-material modification to the Company's investment restrictions, so that investments in Sunfire, measured at the time of investment, shall not exceed 21% of the Company's GAV. The Company's existing restriction of an investment limit of 20% of GAV at the time of investment is unchanged for the remainder of the portfolio.

In April 2024, the Company agreed to a restructuring of HH2E, ahead of planned material third party fund raising for green hydrogen projects in Germany. The Company has exchanged its development rights for five project SPVs, including the Thierbach SPV for equity in HH2E. In parallel, the Lubmin SPV, which was previously carved out of the Company's direct holdings, has also been combined with HH2E in a non-cash transaction for the Company. The Company's previously announced development loan to Thierbach, of which £1.9 million has been drawn, will be reduced to £0.7 million, through a swap for equity in HH2E. The Company's resulting equity share of HH2E is unchanged, at around 11% of an enlarged asset base and with a similar corporate structure, and with direct exposure to the Lubmin project.

Outlook

Our diversified portfolio approach has proved resilient and our investment case has been reinforced further by macro tailwinds and supportive regulatory regimes in the clean hydrogen sector. There are considerable uncertainties on the near-term macro-economic outlook, and a challenging funding environment in private equity, which are affecting valuations across the listed funds sector. Nevertheless, we remain confident that the Company is investing in a sector with a favourable outlook and a substantial growth potential. New regulations and funding for clean hydrogen are being rolled out in the USA, UK and EU.

Whilst market sentiment is outside of our control, the Company anticipates that the continued solid performance of our portfolio, revenue growth and delivery of key milestones will be catalysts for appreciation in our share price.

As we move to exit selected portfolio companies, either partly or entirely, the Board will be focused on protection of invested capital and realising returns. This ambition frames our target to deliver 10-15% annual NAV growth over time, and I believe that our Investment Adviser, whose principals have over 60 years of combined specialist experience and track record, is well placed to deliver on these projected targets.

On behalf of the Board, I would like to thank all of our shareholders for their support, as we continue to develop our portfolio of unique and diverse portfolio of clean hydrogen investments.

About Clean Hydrogen

· Clean hydrogen displaces fossil fuels, reducing CO2 emissions and improving air quality

· Some 90 million tonnes per day of hydrogen is used today in manufacturing of oil products, chemicals and steel. The demand to replace this polluting 'grey' hydrogen, mostly produced from natural gas, with clean hydrogen underpins growth in the clean hydrogen sector

· Clean hydrogen can also replace fossil fuels in hard to decarbonise sectors such as power generation and transport

· Clean hydrogen is an energy carrier, that can store and distribute intermittent renewable electricity at a large scale

· Hydrogen combined with renewables such as wind and solar provides a domestic energy supply option for many countries, reducing reliance on imported energy.

What is driving the hydrogen economy?

Putting all this together, clean hydrogen demand could increase by over 200 times between 2019 and 2030 as the energy transition gathers pace, abating some 6 billion tonnes/year of CO2 emissions by 2050. Announcements at COP28, calling for the transition away from fossil fuels and trebling of renewables, all underpin the positive outlook for the clean hydrogen industry. Clean hydrogen plays a key role in many corporate and country plans for Energy Transition.

By 2050, the global hydrogen market could reach $2.5 trillion, dominated by hydrogen producers, electrolyzer and fuel cell manufacturers. Replacing today's c.$175 billion 'grey' hydrogen market with clean hydrogen could mitigate over 800 million tonnes per annum of greenhouse gas emissions. Some 20 billion tonnes per annum of GHG emissions can be addressed with clean hydrogen over time, which is over one third of all GHG emissions today.

Hydrogen market commentary and outlook

The clean hydrogen sector continues to grow rapidly, despite headwinds from weak financial markets. The Investment Adviser has tracked $17 billion of new investment into clean hydrogen in 2023, over 400% higher than in 2022. This has included landmark project developments such as NEOM Green Hydrogen, which is set to be a 4GW facility in Saudi Arabia, producing 600 tonnes per day of green hydrogen and the go-ahead of a 1GW green hydrogen facility and green steel facilities in Sweden, that will use 1 GW of green hydrogen for electricity generation and as a reducing agent. Alongside these private transactions, the 2023 IPO of ThyssenKrupp Nucera marked a new electrolyzer entrant into public markets, with an enterprise value in excess of €2.5 billion.

Strong increase in investment in clean hydrogen in 2023

Some 1.2GW of green hydrogen production was on line globally at the end of 2023, a 50% increase year-on-year. This includes the start-up of the 260MW Xinjiang Solar Hydrogen Project in China and new liquefied hydrogen facilities in the USA. In addition, there are some 35GW of further projects in development world-wide, an increase of 20% from 2022, which could result in over 40 million tonnes per annum of avoided greenhouse gas emissions.

Policy makers and industry are converging on clean hydrogen as a core technology to deliver net zero, improved air quality and enhanced energy security.

The Paris Agreement in 2015 has led at least 40 countries to set out hydrogen policies and US$70 billion of funding as part of net zero targets to deliver the energy transition.

In response to the Russian invasion of Ukraine, the EU has reshaped its energy policy to the REPowerEU 2030 plan, which calls for over 300GW of clean hydrogen by 2030, compared to 80GW in previous plans. Some €5.4 billion in hydrogen subsidies have recently been approved under Important Projects of Common European Interest ("IPCEI"), which are expected to unlock a further €8.8 billion of private investment. The Hy2Tech links 41 projects and 35 companies building out the hydrogen sector, and has qualified for IPCEI funding. The EU's Hydrogen Bank began the auction of €800 million of opex subsidy to green hydrogen in 2023. There are additional sources of grant funding at a country level in multiple EU countries.

Germany, where the Company has 27% of its NAV, is a leader in this, and has incorporated the RED III Delegated Act into national law, which confirmed a 42% target for use of renewable hydrogen in industry, and announced plans for more stringent measures to curb GHG emissions, including a new hydrogen pipeline system (the "Core Network"), and plans to blend hydrogen with the natural gas grid. Germany's 3mtpa target for hydrogen in 2030 is the same size as the entire US target for clean hydrogen.

In the Netherlands, where the Company has 15% of its NAV, the government has set targets for 3GW to 4GW of electrolysis by 2030 with multi-billion-euro funding support announced by the Netherlands government. The government is providing €750 million of funding support for a "hydrogen backbone", retrofitting existing natural gas pipelines to transport hydrogen between five industrial clusters in the Netherlands, and at cross-border connection points. In May 2023, the Dutch government unveiled a €28 billion climate package, which included €7.5 billion for green hydrogen.

In the UK, 2030 clean hydrogen targets have been doubled during 2023 to 10GW. The UK Government has announced a national clean hydrogen subsidy scheme called Hydrogen Business Model ("HBM"), which will use a contracts-for-difference style set-up to help fund an initial 1GW of clean hydrogen projects, as part of the target to reach 10GW of low‑carbon hydrogen by 2030, in a potentially £9 billion sector. This is in addition to the Net Zero Hydrogen Fund ("NZHF") with up to £240 million of grant funding to support the upfront costs of developing and building low carbon hydrogen production projects.

All of this underscores the positive industry outlook and supportive regulatory regimes for clean hydrogen. This improving outlook for clean hydrogen demand underpins the order books in many of the Company's investments, particularly in supply chain sectors such as electrolyzers, fuel cells, storage and transportation businesses. Many of these businesses have world-wide customer bases for their products, and are attracting investment from international financial and strategic investors.

Q&A with the Investment Advisor

Dr JJ Traynor and Richard Hulf

In this section, we address some of the questions that we frequently hear from investors and commentators in the hydrogen industry.

Is green hydrogen in production today, or is this just an emerging technology?

Yes, this is a producing industry, today, with very strong growth potential. We are tracking 1.2GW of green hydrogen in production at the end of 2023, which is an increase of 50% compared to 2022. Projects in design total 35GW, a near 30‑fold increase should all this production come on stream. The UK, where many of the readers of this report will be based, has not historically been a leader in green hydrogen, but has plans and government funding in place for 5GW of green hydrogen by 2030, compared to essentially zero today.

Who is buying green hydrogen?

Presently, most of the demand for green hydrogen comes from chemical plants, oil refineries and the fertiliser sector, as these industries look to replace polluting 'grey' hydrogen in their industrial processes with green hydrogen. As an example, TotalEnergies announced a tender for 500,000 tonnes per year of green hydrogen for its European refineries, in 2023, to decarbonise all of the hydrogen used on these sites by 2030. We also see strong growth in demand for green hydrogen in heavy ground transport, particularly in EU bus fleets and commercial trucks, and in some regions in the United States. HydrogenOne portfolio companies have supplied equipment for transportation of hydrogen in Germany, during 2023, and signed supply agreements for green hydrogen there.

Will blue hydrogen remove the need for green hydrogen?

Blue hydrogen has been in production in North America for some 15 years, using natural gas as a feedstock, and geological carbon capture for the resulting CO2 emissions. This is not a new technology. We do expect further growth in blue hydrogen, as well as green, especially in countries with legacy natural gas production and geological sites for CCS. Energy transition policies in the USA and UK support this trend. However, since blue hydrogen fundamentally encourages more exploration and development of polluting fossil fuels, we expect green hydrogen to dominate the supply picture and investment thinking in the future, and to compete with blue on supply cost.

Will hydrogen break into the transport sector?

Yes. Battery electric is the best option for cars over short to medium distances. However, batteries cannot store enough energy at a reasonable size to move heavy vehicles over long distances. Hydrogen fuel cells are the best option for trucks, trains (on tracks that are not electrified), fork lift and SUV. Most auto companies are developing hydrogen fuel cell vehicles currently. With some 80,000 fuel cell electric vehicles ("FCEV") in use worldwide today, hydrogen has arrived as a viable transport fuel for medium to heavy trucks, trains, and forklifts. The shipping market and aviation are fast emerging as the next wave of hydrogen for transport applications.

Some 814 hydrogen refuelling stations are already in operation worldwide. Concrete plans are already in place for 315 additional refuelling station locations. Europe has 254 hydrogen stations currently, 105 of which are in Germany. France is still second in Europe with 44 operating stations, followed by the UK and the Netherlands with 17 each. The USA alone has over 100,000 gasoline stations and globally there could be 400,000 of these. The incumbents, mostly oil companies, are looking for ways to green up these otherwise-stranded assets.

Isn't clean hydrogen high cost and it won't be able to compete with fossil fuels?

Economic recovery from COVID and Russia's invasion of Ukraine have resulted in more 'normal' fossil fuel prices c.$80-$120 Brent. This is a markedly-different position than the 2015-2020 "$40" world, and reflects the real replacement cost of fossil fuels. As an example, all of the big oil companies now have hydrogen and carbon capture strategies - ExxonMobil see hydrogen as a $1tn market medium term; BP see hydrogen as up to 15% of the energy mix long term. The debate has really shifted to the timescales, rather than price competition.

Can you drill for native hydrogen, like you do for oil & gas?

Native hydrogen has been found in volcanic rocks, salt mines and sedimentary rocks, most notably in water wells drilled in Mali in the 1980s, and recent announcements of discoveries in France. This could be an important source of hydrogen, that could have a role in stimulating the hydrogen market and switching away from fossil fuels. The shipping costs of hydrogen over long distances are prohibitive, as are the clean-up costs to make fuel cell purity hydrogen, and there are considerable financial risks with exploration drilling for hydrogen. All of this makes the outlook for native hydrogen uncertain, but it could play an important role in the growth of this industry.

Will hydrogen be blended in natural gas networks and used in domestic boilers?

We are seeing hydrogen blending gathering pace in many countries, for consumption in power plants and domestic environments. Town gas, made from coal, is 20-50% hydrogen, and was used in the UK until the 1970s, and is in use today in Hong Kong. Germany has authorized 10% hydrogen blending. In the UK, the government is assessing next steps on blending, probably to 20%, following testing led by Keele University and HyDeploy. Most domestic boilers in the UK can burn 20% hydrogen blend today. Pure hydrogen networks (100% hydrogen) are more likely to be for dedicated supply to industrial customers, particularly refineries and chemicals plants, rather than domestic customers.

What is happening with policy support for clean hydrogen?

Globally we see at least 40 countries with hydrogen policies and some $70 billion of funding, all as part of government plans for energy transition. There are a range of policies on the table for investors:

In the EU, the REPowerEU 2030 plan calls for over 300GW of clean hydrogen by 2030. Some EUR 5.4 billion in hydrogen subsidies have recently been approved under Important Projects of Common European Interest ("IPCEI"), which are expected to unlock a further EUR 8.8bn of private investment. The EU's Hydrogen Bank auctioned EUR 800 million of opex subsidy to green hydrogen in 2023. There are additional sources of grant funding at a country level in multiple EU countries.

In the United States, the Department of Energy has announced a US$8bn programme to develop clean regional hydrogen hubs across the country, as part of net zero ambitions by 2050. The 2022 Inflation Reduction Act set aside US$369bn for climate and energy proposals. Within this Act, there is a tax credit for clean hydrogen of US$0.6/kg to US$3/kg, depending on life cycle emissions. This is expected to make green hydrogen cost competitive with grey hydrogen and make US clean hydrogen amongst the lowest cost in the world.

In the UK, 2030 clean hydrogen targets have been doubled during 2023 to 10GW. The UK Government has recently announced a national clean hydrogen subsidy scheme called Hydrogen Business Model ("HBM"), which will use a contracts-for-difference style set-up to help fund an initial 1GW of clean hydrogen projects in 2023, as part of the target to reach 10GW of low-carbon hydrogen by 2030, in a potentially £9 billion sector. This is in addition to the Net Zero Hydrogen Fund ("NZHF") with up to £240 million of grant funding to support the upfront costs of developing and building low carbon hydrogen production projects.

Investment objective, policy, process and strategy

Investment objective

The Company's investment objective is to deliver an attractive level of capital growth by investing, directly or indirectly, in a diversified portfolio of hydrogen and complementary hydrogen focussed assets whilst integrating core ESG principles into its decision making and ownership process.

Investment policy

The Company will seek to achieve its investment objective through investment in a diversified portfolio of hydrogen and complementary hydrogen focussed assets, with an expected focus in developed markets in Europe, North America, the GCC and Asia Pacific, comprising:

i. assets that produce clean hydrogen;

ii. large scale energy storage assets;

iii. carbon capture, use and storage assets;

iv. hydrogen distribution infrastructure assets;

v. assets involved in hydrogen supply chains, such as electrolyzers and fuel cells; and

vi. businesses that utilise hydrogen applications such as transport, power generation, feedstock and heat (together "Hydrogen Assets").

The Company intends to implement its investment policy through the acquisition of hydrogen and complementary hydrogen focussed assets.

Private Hydrogen Assets

The Company invests in unquoted Hydrogen Assets, which may be operational companies or hydrogen projects (completed or under construction) ("Private Hydrogen Assets"). Investments are expected to be mainly in the form of equity, although investments may be made by way of debt and/or convertible securities. The Company may acquire a mix of controlling and non-controlling interests in Private Hydrogen Assets, however the Company intends to invest principally in non-controlling positions (with suitable minority protection rights to, inter alia, ensure that the Private Hydrogen Assets are operated and managed in a manner that is consistent with the Company's investment policy).

Given the time frame required to fully maximise the value of an investment, the Company expects that investments in Private Hydrogen Assets will be held for the medium to long term, although short term disposals of assets cannot be ruled out in exceptional or opportunistic circumstances. The Company intends to re-invest the proceeds of disposals in accordance with the Company's investment policy.

The Company observes the following investment restrictions, assessed at the time of an investment, when making investments in Private Hydrogen Assets:

· no single Private Hydrogen Asset will account for more than 20 per cent. of Gross Asset Value;

· Private Hydrogen Assets located outside developed markets in Europe, North America, the GCC and Asia Pacific will account for no more than 20 per cent. of Gross Asset Value; and

· at the time of an investment, the aggregate value of the Company's investments in Private Hydrogen Assets under contract to any single Offtaker will not exceed 40 per cent. of Gross Asset Value.

The Company will initially acquire Private Hydrogen Assets via HydrogenOne Capital Growth Investments 1 LP (the 'HydrogenOne Partnership'), a wholly owned subsidiary undertaking of the Company structured as an English limited partnership which is controlled by the Company and advised by the Investment Adviser. The HydrogenOne Partnership's investment policy and restrictions are the same as the Company's investment policy and restrictions for Private Hydrogen Assets and cannot be changed without the Company's consent. In due course, the Company may acquire Private Hydrogen Assets directly or by way of holdings in special purpose vehicles or intermediate holding entities (including successor limited partnerships established on substantially the same terms as the HydrogenOne Partnership) or, if the Company is considered a 'feeder fund' under the Listing Rules, other undertakings advised by the Investment Adviser and, in such circumstances, the investment policy and restrictions will also be applied on a look-through basis and such undertaking(s) will also be managed in accordance with the Company's investment policy.

Listed Hydrogen Assets

The Company also invests in quoted or traded Hydrogen Assets, which will predominantly be equity securities but may also be corporate debt and/or other financial instruments ("Listed Hydrogen Assets"). The Company is free to invest in Listed Hydrogen Assets in any market or country with a market capitalisation (at the time of investment) of at least US$100 million. The Company's approach is to be a long-term investor and will not ordinarily adopt short-term trading strategies. As the allocation to Private Hydrogen Assets grows the Listed Hydrogen Assets are expected to include strategic equity holdings derived from the listing of operational companies within the Private Hydrogen Assets portfolio over time.

The Company observes the following investment restrictions, assessed at the time of an investment, when making investments in Listed Hydrogen Assets:

· no single Listed Hydrogen Asset will account for more than 3 per cent. of the Gross Asset Value;

· the portfolio of Listed Hydrogen Assets will typically comprise no fewer than 10 Listed Hydrogen Assets at times when the Company is substantially invested;

· each Listed Hydrogen Asset must derive at least 50 per cent. of revenues from hydrogen and/or related technologies; and

· once fully invested, the target allocation to Listed Hydrogen Assets will be approximately 10 per cent or less of Gross Asset Value, subject to a maximum allocation of 30 per cent of Gross Asset Value.

Cash

During the initial Private Hydrogen Asset investment period after a capital raise and/or a realisation of a Private Hydrogen Asset, the Company intends to hold the relevant net proceeds of such capital raise/realisation in cash (in accordance with the Company's cash management policy set out below) pending subsequent investment in Private Hydrogen Assets.

Investment restrictions

The Company, in addition to the investment restrictions set out above, comply with the following investment restrictions when investing in Hydrogen Assets:

· the Company will not conduct any trading activity which is significant in the context of the Company as a whole;

· the Company will, at all times, invest and manage its assets

i. in a way which is consistent with its object of spreading investment risk; and

ii. in accordance with its published investment policy;

· the Company will not invest in other UK listed closed-ended investment companies; and

· no investments will be made in companies or projects that generate revenues from the extraction or production of fossil fuels (mining, drilling or other such extraction of thermal coal, oil or gas deposits).

Compliance with the above restrictions is measured at the time of investment and non-compliance resulting from changes in the price or value of Hydrogen Assets following investment will not be considered as a breach of the investment policy or restrictions.

Borrowing policy

The Company may take on debt for general working capital purposes or to finance investments and/or acquisitions, provided that at the time of drawing down (or acquiring) any debt (including limited recourse debt), total debt will not exceed 25 per cent of the prevailing Gross Asset Value at the time of drawing down (or acquiring) such debt. For the avoidance of doubt, in calculating gearing, no account will be taken of any investments in Hydrogen Assets that are made by the Company by way of a debt investment.

Gearing may be employed at the level of a special purpose vehicle ("SPV") or any intermediate subsidiary undertaking of the Company (such as the HydrogenOne Partnership) or, if the Company is considered a 'feeder fund' under the Listing Rules, other undertakings advised by the Investment Adviser in which the Company has invested or the Company itself. The limits on debt shall apply on a consolidated and look-through basis across the Company, the SPV or any such intermediate holding entities (such as the HydrogenOne Partnership) or, if the Company is considered a 'feeder fund' under the Listing Rules, other undertakings advised by the Investment Adviser in which the Company has invested but intra-group debt will not be counted.

Gearing of one or more Hydrogen Assets in which the Company has a non-controlling interest will not count towards these borrowing restrictions. However, in such circumstances, the matter will be brought to the attention of the Board who will determine the appropriate course of action.

Currency and hedging policy

The Company has the ability to enter into hedging transactions for the purpose of efficient portfolio management. In particular, the Company may engage in currency, inflation, interest rates, energy prices and commodity prices hedging. Any such hedging transactions will not be undertaken for speculative purposes.

Cash management

The Company may hold cash on deposit and may invest in cash equivalent investments, which may include short-term investments in money market type funds ("Cash and Cash Equivalents").

There is no restriction on the amount of Cash and Cash Equivalents that the Company may hold and there may be times when it is appropriate for the Company to have a significant Cash and Cash Equivalents position. In particular, the Company anticipates holding cash to cover the near-term capital requirements of the Pipeline of Private Hydrogen Assets and in periods of high market volatility. For the avoidance of doubt, the restrictions set out above in relation to investing in UK listed closed-ended investment companies do not apply to money market type funds.

Investment process

The Company follows a proven and successful process in order to access and execute its distinctive deal flow. The Investment Adviser has specialist insights and strong industry and market networks to access potential investment opportunities. The Company typically invests alongside some of the world's largest industrial corporations and investors. The Investment Adviser's clear investment and ESG policies underpin and guide everything that it does. The Investment Adviser, the Advisory Board, the technical advisors, regulatory and legal counsel all combine to deliver the optimal deal structures for the shareholders.

Strategy, business model and KPIs

A highly differentiated strategy, 100% focussed on clean hydrogen

The Company offers distinctive access to private investments, across the full hydrogen value chain, and across the OECD. The investment objective is to deliver an attractive level of capital growth by investing, directly or indirectly, in a diversified portfolio of hydrogen and complementary hydrogen focussed assets whilst, as a SFDR Article 9, PRI and Green Economy Mark company, integrating core ESG principles into our decision making and ownership process, for a positive environmental impact.

As the first UK listed investment company specialising in this sector, the Company has a clear competitive advantage as an early mover into a complex sector, and offers its investors a unique window into the private hydrogen asset market. With its emphasis on Private Hydrogen Assets, the Company, gives investors an opportunity to be exposed to liquidity and portfolio diversity in hydrogen companies and projects, hard to access elsewhere, with strong growth potential.

An investment in the Company offers exposure to the broader hydrogen sector whilst, at the same time, diversifying risk for an investor. By targeting a diversified portfolio of listed and private investments across different jurisdictions and different technologies, the Company seeks to spread some of the key underlying risks relating to clean hydrogen.

A focus on material ESG factors, and especially the deployment of capital to deliver the energy transition to a low carbon economy, is at the heart of what the Investment Adviser does, running hand in hand with a strategy to deliver the target 10-15% per annum NAV growth for the investors over the medium to long term.

The Investment Adviser is a specialist investor in this complex and rapidly-developing growth sector. The Company believes that this specialised approach is a competitive advantage that will only grow over time.

By excluding companies or projects that generate revenues from the extraction or production of fossil fuels (mining, drilling or other such extraction of thermal coal, oil or gas deposits) from the portfolio and taking on further ESG screens, the portfolio is expected to be an early mover to Net Zero in the energy transition, and will not be encumbered by the legacy greenhouse gas emissions inherent in other players in the hydrogen sector.

The clean hydrogen industry in the short term is dominated by bespoke sources of supply, financed by specialised offtakers, typically at 5MW to 100MW scale. In the period from 2025 to 2030 the Investment Adviser expects these facilities to be upscaled to 100MW to 500MW scale, and ultimately to 1GW to 5GW. The Investment Adviser also believes that energy storage and CCS projects will also increase in scale in this timeframe, with the development of compressed air energy storage followed by hydrogen storage and long-distance transport through pipelines, as liquid hydrogen or as ammonia on ships.

Business model

The Company is an investment company and its purpose, strategy, investment objective and policy are set out in the Annual Report. Any material change to the investment policy requires shareholder approval.

The Company makes its investment in Private Hydrogen Assets through HydrogenOne Capital Growth Investments (1) LP (the "HydrogenOne Partnership" or the "Limited Partnership"), in which the Company is the sole limited partner. The Company may also acquire Private Hydrogen Assets directly or by way of holdings in special purpose vehicles or intermediate holding entities.

The General Partner of the Limited Partnership is HydrogenOne Capital Growth (GP) Limited (the "General Partner"), a wholly owned subsidiary of the Company. Details of the Company and Group structure are given in note 1 to the Parent and Consolidated Financial Statements (the "Financial Statements"). Other than where specified, references to the Company in this document refer to the Company together with its wholly-owned subsidiary and investment as sole limited partner in the Limited Partnership.

The Company is governed by a Board of Directors (the "Board"), all of whom are non-executive, and it has no employees. The business model adopted by the Board to achieve the Company's objective has been to contract the services of FundRock Management Company (Guernsey) Limited as the alternative investment fund manager of the Company, pursuant to the AIFM Agreement (the "AIFM"). The AIFM has appointed HydrogenOne Capital LLP to provide investment advisory services in respect of the Company (the "Investment Adviser"). The Investment Adviser will advise on the portfolio in accordance with the Board's strategy and under its and the AIFM's oversight. The Principals of the Investment Adviser responsible for the day-to-day monitoring of the portfolio are Dr John Joseph "JJ" Traynor and Richard Hulf. The Board and the AIFM monitor adherence to the Company's investment policy and regularly reviews the Company's performance in meeting its investment objective.

All administrative support is provided by third parties under the oversight of the Board. Company secretarial and administration services have been delegated to Apex Listed Companies Services (UK) Limited ("Apex" or the "Administrator"); custody services to Northern Trust Company ("Northern Trust"); registrar services to Computershare Investor Services plc ("Computershare"); and effective 12 January 2023, the Company's broker is Barclays Bank PLC ("Barclays" or the "Broker"). Prior to this date the Company's broker was Panmure Gordon (UK) Limited.

The Board reviews the performance of the AIFM, the Investment Adviser and other key service providers on an ongoing basis. Further details of the material contracts of the Company are given in note 14 to the Financial Statements.

Portfolio review, performance and valuation

Capital Deployment since IPO and Pipeline¹

The Company has invested £113.7 million in ten Private Hydrogen Assets and a portfolio of listed equities since its 2021 IPO to 31 December 2023, directly or via the HydrogenOne Partnership. The private companies account for 95% of the NAV of the Company, and span the full value chain in the clean hydrogen sector. The portfolio is dominated by supply chain businesses, particularly electrolyzer and fuel cell makers such as Elcogen and Sunfire. There are further investments in storage and distribution businesses, such as Strohm, and project developers setting up green hydrogen production facilities. Whilst the UK accounts for over half of the portfolio by geography, the Investment Advisor assesses that the bulk of sales from portfolio companies are derived from the EU and Asia Pacific.

1 Capital deployed is comprised of the acquisition costs of Listed Hydrogen Assets (2023: £nil, 2022: £nil, 2021: £9.4 million) and Private Hydrogen Assets acquired by the Limited Partnership (2023: £10.6m, 2022: £54.3 million, 2021: £39.2 million).

Distinctive and unique hydrogen portfolio

At the time of its IPO, the Company had an Investible Universe of c.120 Private Hydrogen Assets of private companies and hydrogen production projects. Since the IPO, the Company has seen significant expansion of its opportunity set in both private companies and hydrogen production projects, at least double the number of opportunities since the IPO. At the same time, the Company now sees material opportunities to invest in green hydrogen production projects, with financial close and final investment decision expected in the Company's portfolio developer businesses during 2024, in Norway and Germany. These projects, alongside further hydrogen opportunities build out to an investment pipeline of some £500 million available for the Company's investors in the future.

Alongside this expansion in the opportunity set, the Company has seen the arrival of multiple industrial investors into the hydrogen sector. This is typically incumbent consumers of grey hydrogen, and companies seeking to access clean hydrogen supplies and technologies. The Company is invested alongside multiple industrial strategic investors today.

The Company has been investing in follow-ons in its existing portfolio during 2023, alongside existing investors, and new investors, against the backdrop of a challenging environment for fund raising for the hydrogen sector and the Company. The Company will likely require a fresh capital raise in order to invest in any new pipeline opportunities.

Investing alongside blue-chip industrials and funds

The Company has invested in a range of private hydrogen businesses across the value chain. Early-stage businesses, such as Cranfield Aerospace and HiiROC, are developing high quality intellectual property and investing in demonstrator facilities, ahead of full roll-out of commercial solutions. Mid stage companies, for example Bramble, are commencing commercial sale of their technology and products, and typically have single digit millions of pounds of revenues, and negative EBITDA. Growth businesses are fundamentally larger and more developed, with investment in order to build industrial scale factories and world-wide customer bases for their products, with a clear visibility to positive EBITDA. Whilst these growth businesses are best placed for IPO into public markets in the coming years, which would mark an exit for the Company, the Company also expects to be able to exit from earlier stage businesses through trade sales, to industrial strategic investors.

				2023: £74m (+125% vs 2022)

Valuation

As set out in note 4 of the Financial Statements, the Investment Adviser has carried out fair market valuations of the Private Hydrogen Assets at 31 December 2023, which have been reviewed by the Valuation Committee, and the Directors have satisfied themselves as to the methodology used, the discount rates and key assumptions applied.

Private Hydrogen Assets at 31 December 2023 have been valued using either the discounted cash flow ('DCF') methodology, the value of the loan principal plus accrued interest for loans to Project Development companies or a scenario based valuation incorporating DCF, indicative offers and net asset values consistent with the International Private Equity and Venture Capital Valuation ("IPEV") Guidelines. The valuations are also benchmarked against listed peer group valuations.

Listed Hydrogen Assets are valued at fair value, which is the bid market price, or, if bid price is unavailable, last traded price on the relevant exchange.

Our approach to valuation remains consistent and unchanged. Valuations are updated for all Private Hydrogen Assets on a quarterly basis and approved by the AIFM, the Valuation Committee and the Board, and are audited annually by the Company's auditor, KPMG.

Discount rates are calculated using market parameters for each investment domicile. The weighted average discount rate for 31 December 2023 was 14.2 % compared with 13.0% at December 2022.

The Company notes that its NAV has been steadily increasing over the last twelve months. This has been driven by organic growth in the Company's private assets, despite headwinds from lower share prices of the listed portfolio companies and higher discount rates. The share prices of listed hydrogen companies, which we track with the Solactive Hydrogen Economy Index ("SOLGHYD"), have been volatile and declining since Q3 2021. This decline is due to market allocation away from early-stage technology businesses as interest rates have risen, and a correction to the high valuations seen in the market in 2020-21.

The Company's own share price has tracked this decline in listed hydrogen companies, and listed funds in general, despite the growth in NAV. In 2021-22, the Company assessed that many listed hydrogen companies were trading on higher valuations than its private portfolio companies, based on forward multiples of revenues. At the end of 2023, the revenue multiples of the listed hydrogen sector and the Company's private portfolio had converged, as the listed hydrogen sector had de-rated.

The Company's approach to valuation remains consistent while market has seen strong rise and correction

· Listed hydrogen company valuations have decreased in 2022-23, whereas HGEN NAV has been steady, reflecting our consistent valuation methodology

· Forward revenue multiple of c. 9.8X (2025E) in private portfolio is in line with listed hydrogen companies

2023 Performance and 2024 outlook

NAV per share increased by 5.8% from 31 December 2022 to 31 December 2023 (97.31p to 102.99p), with NAV growing from £125.4 million to £132.7 million over the period.

The NAV increase was driven primarily by valuation uplifts in nine private companies, positively contributing 10.8 pence per share. The main factors behind this growth were roll-forward of discounted cash flow ("DCF") valuations, and improving financial performance from the portfolio companies. Discount rates had a negative impact on valuation in 2023. The portfolio weighted average discount rate at 31 December 2023 was 14.2%, higher than 31 December 2022 (13.0%), decreasing NAV by 6.7 pence per share, or £8.6 million.

Portfolio valuation changes 2022-23

During the 12 months to 31 December 2023, private portfolio companies delivered an aggregate unaudited £74 million in revenue, a 125% increase compared to the year ended 31 December 2022, on a pro-forma basis. Seven of the ten private companies are revenue generating. Thierbach and Gen2 Energy are project developers that are inherently pre-revenue businesses ahead of the start-up of green hydrogen production, and HiiROC is expected to commence revenue generation from its thermal plasma electrolyzer business from 2024. These positive financial trends reflect the build out of capacity to meet strong order books for hydrogen supply chain equipment.

The portfolio is revenue generating and has produced consistent growth

· 8 private companies are revenue-generating

· 2023 revenue growth +125% to £74m

Revenue 100% basis for private portfolio companies

Investments in 2023 totalled £10.6 million in 5 existing portfolio companies, as well as one new position, the Thierbach Project, a green hydrogen development in Germany, which is being managed by portfolio company HH2E.

Cash and cash equivalents were £4.6 million, with additionally £2.3 million of listed hydrogen companies at the end of the year.

We continue to see strong investment interest from industrial strategic investors in portfolio companies and the hydrogen industry at large in 2023, and note that Cemex and HD Hyundai invested in HydrogenOne businesses during the year, which underpin the investment cases and bring strategic partnerships to the businesses.

The UK Government continues to support the development of clean hydrogen supply, yet has elected to slow the pace of fossil fuel phase out in transport, which has reduced the pace of deployment of clean hydrogen in the UK into transport. In light of this development, and weak financial markets, we have restructured NanoSUN and relaunched in early 2024 as Swift Hydrogen, which has a lower cost base and simplified capital structure, for renewed growth in the business, with customers in the EU in the near term. The December 2023 valuation for NanoSUN reflects a scenarios based analysis of potential outcomes for the business that existed as of the valuation date, resulting in a reduction in the value for NanoSUN compared to 31 December 2022. The restructuring of NanoSUN was completed in February 2024, and will be reported in the unaudited first quarter 2024 results.

In the year to 31 December 2023, the gains on fair value of investments were £9.2 million (31 December 2022: £3.2 million).

The expenses included in the income statement for the year were £2.0 million, in line with expectations. These comprise £0.1 million Investment Adviser fees and £1.9 million operating expenses. The details on how the Investment Adviser fees are charged are as set out in note 6 to the Financial Statements.

Ongoing charges

The 'ongoing charges' ratio is an indicator of the costs incurred in the day-to-day management of the Company.

The ongoing charges percentage for the year to 31 December 2023 was 2.56% (31 December 2022: 2.51%). The ongoing charges have been calculated, in accordance with AIC guidance, as annualised ongoing charges (i.e. excluding acquisition costs and other non-recurring items) divided by the average published undiluted Net Asset Value in the period. The calculation is provided in the annual report. The ongoing charges percentage has been calculated on the amalgamated basis and therefore takes into consideration the expenses of HydrogenOne Partnership as well as the Company.

Methodology

Emissions are calculated in line with the Greenhouse Gas Protocol but disclosed in line with EU SFDR (which aggregates the Company's share of emissions for each scope).

Principles of Responsible Investment

During the year the Company submitted its first reporting to the Principles of Responsible Investment. The charts below show the scoring vs the peer group of investment managers in the same jurisdiction with similar assets under management. The results are favourable to the Company with performance above the median average in all three categories and particularly strong results in governance. Further work to enhance responsible investment performance will be undertaken in FY 2024.

Stakeholder engagement (Section 172 Statement)

The Company has no employees and no customers in the traditional sense. In accordance with the Company's nature as an investment trust the Board's principal concern is the interests of the Company's shareholders taken as a whole. In doing so, it has due regard to the impact of its actions on shareholders, the environment and the wider community.

Other Matters

Modern slavery disclosure

The Company is committed to maintaining the highest standards of ethical behaviour and expects the same of its business partners. The use of slavery and human trafficking is unacceptable and entirely incompatible with its ethics as a business. The Company believes that all efforts should be made to eliminate it from its supply chains.

The majority of services supplied to or on behalf of the Company are from the financial services, energy and construction industries and other services associated with those industries. Given what the Company understands to be a low risk profile of anyone supplying it with services being involved in slavery and/or human trafficking, it believes its current procedures and ability to rely on regulatory oversight in relation to professional services are sufficient in this regard.

Social, community and human rights issues

The Investment Adviser screens the Company's Investable Universe as part of the Environmental Social and Governance analysis for any breaches of the principles of the UN Global Compact, including human rights, labour rights, environmental breaches and corruption. Any non-compliant companies are excluded from investment.

Anti-bribery and corruption

In accordance with the UK Bribery Act 2010, the Company has developed appropriate anti-bribery policies and procedures. The Company has a zero-tolerance policy towards bribery and is committed to carrying out its business fairly, honestly and openly. The anti-bribery policies and procedures apply to all its officers and to those who represent the Company (including its business partners). The Company expects those providing services to it, or on its behalf, to undertake their business without bribery.

Prevention of the facilitation of tax evasion

The Criminal Finances Act (Commencement No. 1) Regulations 2017 (SI 2017/739) brought Part 3 of the Criminal Finances Act 2017, the corporate offences of failure to prevent facilitation of tax evasion, into force on 30 September 2017. The Company does not tolerate tax evasion in any of its forms in its business. The Company complies with the relevant UK law and regulation in relation to the prevention of facilitation of tax evasion and supports efforts to eliminate the facilitation of tax evasion worldwide, and works to make sure its business partners share this commitment.

Statement of Directors' Responsibilities

The Directors are responsible for preparing the Annual Report and the Group and Parent Company Financial Statements in accordance with applicable laws and regulations.

Company law requires the Directors to prepare Group and Parent Company financial statements for each financial year. Under that law they are required to prepare the Group Financial Statements in accordance with UK-adopted international accounting standards and applicable law and have elected to prepare the parent Company financial statements on the same basis.

Under company law the Directors must not approve the Financial Statements unless they are satisfied that they give a true and fair view of the state of affairs of the Group and Parent Company and of the Group's profit or loss for that year. In preparing each of the Group and Parent Company Financial Statements, the Directors are required to:

· select suitable accounting policies and then apply them consistently;

· make judgements and estimates which are reasonable relevant and reliable;

· state whether they have been prepared in accordance with UK-adopted international accounting standards;

· assess the Group and Parent Company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern; and

· use the going concern basis of accounting unless they either intend to liquidate the Group or the Parent Company or to cease operations, or have no realistic alternative but to do so.

The Directors are responsible for keeping adequate accounting records that are sufficient to show and explain the Company's transactions and which disclose with reasonable accuracy at any time the financial position of the Company and enable them to ensure that its financial statements comply with the Companies Act 2006. They are responsible for such internal control as they determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error, and have general responsibility for taking such steps as are reasonably open to them to safeguard the assets of the Group and to prevent and detect fraud and other irregularities.

Under applicable law and regulations, the Directors are also responsible for preparing a Strategic Report, Directors' Report, Directors' Remuneration Report and Corporate Governance Statement that complies with that law and those regulations.

The Directors are responsible for the maintenance and integrity of the corporate and financial information included on the company's website. Legislation in the UK governing the preparation and dissemination of financial statements may differ from legislation in other jurisdictions.

Responsibility statement of the Directors in respect of the annual report

The Directors each confirm to the best of their knowledge that:

· the Financial Statements, prepared in accordance with the applicable set of accounting standards, give a true and fair view of the assets, liabilities, financial position and profit or loss of the Company and the undertakings included in the consolidation taken as a whole; and

· the Strategic Report includes a fair review of the development and performance of the business and the position of the issuer and the undertakings included in the consolidation taken as a whole, together with a description of the principal risks and uncertainties that they face.

The Directors consider the annual report and accounts, taken as a whole, is fair, balanced and understandable and provides the information necessary for shareholders to assess the Group's position and performance, business model and strategy.

Notes to the parent and consolidated financial statements

iii. 1. General information

Company information

HydrogenOne Capital Growth plc (the "Company" or "Parent") was incorporated in England and Wales on 16 April 2021 with registered number 13340859 as a public company limited by shares and is an investment company within the terms of Section 833 of the Companies Act 2006 (the "Act"). The Company is listed and began trading on the Main Market of the London Stock Exchange and was admitted to the premium segment of the Official List on 30 July 2021 (the "IPO"). The Company has applied for and been accepted as an approved investment trust under sections 1158 and 1159 of the Corporation Tax Act 2010 and Part 2 Chapter 1 of Statutory Instrument 2011/2999.

FundRock Management Company (Guernsey) Limited acts as the Company's Alternative Investment Fund Manager ("AIFM").

Apex Listed Companies Services (UK) Limited (the "Company Secretary and Administrator") provides administrative and company secretarial services to the Company.

The Company's Investment Adviser is HydrogenOne Capital LLP.

The Company's registered office is 6^th Floor, 125 London Wall, London, EC2Y 5AS.

Investment objective

The Company's investment objective is to deliver an attractive level of capital growth by investing, directly or indirectly, in a diversified portfolio of hydrogen and complementary hydrogen focused assets whilst integrating core environmental, social and governance ("ESG") principles into its decision making and ownership process.

Company structure

The Company makes its investments in unquoted Hydrogen Assets ("Private Hydrogen Assets") through HydrogenOne Capital Growth Investments (1) LP (the "Limited Partnership"), in which the Company is the sole Limited Partner. The Limited Partnership registered as a private fund limited partnership in England and Wales under the Limited Partnerships Act 1907 with registered number LP021814. The Limited Partnership has been established pursuant to the Limited Partnership Agreement dated 5 July 2021 as amended and restated on 26 November 2021 (the "Limited Partnership Agreement") in order to make investments pursuant to the investment policy of the Limited Partnership. The Limited Partnership's investment policy and restrictions are consistent with the Company's investment policy and restrictions for Private Hydrogen Assets.

The General Partner of the Limited Partnership is HydrogenOne Capital Growth (GP) Limited (the "General Partner"), a wholly owned subsidiary of the Company. The General Partner was incorporated in England and Wales on 19 May 2021 with company registered number 13407844. The General Partner undertakes the responsibility for the management, operation and administration of the business and affairs of the Limited Partnership. The General Partner's Profit Share for each accounting period shall be an amount equal to 1.5% per annum of the prevailing NAV of the Limited Partnership, which shall be allocated to the General Partner as a first charge on the profits of the Limited Partnership. For so long as the Company is the sole Limited Partner, the General Partner's Profit Share shall be allocated and distributed to the Company rather than the General Partner.

The carried interest partner of the Limited Partnership is HydrogenOne Capital Growth (Carried Interest) LP (the "Carried Interest Partner") which, in certain circumstances, will receive carried interest on the ocusedion of Private Hydrogen Assets by the Limited Partnership. The Carried Interest Partner has been set up for the benefit of the principals of the Investment Adviser. Further details of the carried interest fees payable to the Carried Interest Partner are given in Note 6 to the Financial Statements.

Private Hydrogen Assets

The Company invests via the Limited Partnership in Private Hydrogen Assets, which may be operational companies or hydrogen projects. Investments are mainly in the form of equity, although investments may be made by way of debt and/ or convertible securities. The Company may acquire a mix of controlling and non-controlling interests in Private Hydrogen Assets, however the Company invests principally in non-controlling positions (with suitable minority protection rights to, inter alia, ensure that the Private Hydrogen Assets are operated and managed in a manner that is consistent with the Company's investment policy).

The Company acquires Private Hydrogen Assets via the Limited Partnership. In due course, the Company may acquire Private Hydrogen Assets directly or by way of holdings in special purpose vehicles or intermediate holding entities (including successor limited partnerships established on substantially the same terms as the Limited Partnership) or, if the Company is considered a 'feeder fund' under the Listing Rules, other undertakings advised by the Investment Adviser and, in such circumstances, the investment policy and restrictions will also be applied on a look-through basis and such undertaking(s) will also be managed in accordance with the Company's investment policy.

Listed Hydrogen Assets

The Company also invests directly in quoted or traded Hydrogen Assets, which are predominantly equity securities but may also be corporate debt and/or other financial instruments ("Listed Hydrogen Assets"). The Company has the ability to invest in Listed Hydrogen Assets in any market or country with a market or country with a market capitalisation (at the time of investment) of at least US$100 million. The Company's approach is to be a long-term investor and does not ordinarily adopt short-term trading strategies.

Liquidity reserve

During the initial Private Hydrogen Asset investment period after a capital raise and/or a realization of a Private Hydrogen Asset, the Company intends to allocate the relevant net proceeds of such capital raise/realisation to cash (in accordance with the Company's cash management policy) and/or additional Listed Hydrogen Assets and related businesses pending subsequent investment in Private Hydrogen Assets (the ''Liquidity Reserve'').

The Company anticipates holding cash to cover the near-term capital requirements of the pipeline of Private Hydrogen Assets and in periods of high market volatility.

2. Basis of preparation

The principal accounting policies are set out below:

Reporting entity

These Parent and Consolidated Financial Statements (the "Financial Statements") present the results of both the Parent; and the Parent and the General Partner (together referred to as the "Group").

As at 31 December 2023, the statement of financial position of the General Partner consisted of issued share capital and corresponding share capital receivable in the amount of £1 (2022:£1). The General Partner had no income, expenditure or cash flows for the year (2022: nil).

Due to the immaterial balances of the General Partner there is no material difference between the results of the Parent and the results of the Group. As a result, the Financial Statements as presented represent both the Parent's and the Group's financial position, performance and cash flows.

Basis of accounting

The Financial Statements have been prepared in accordance with UK-adopted international accounting standards ("IFRS") and the applicable legal requirements of the Companies Act 2006.

The Financial Statements have also been prepared as far as is relevant and applicable to the Company and Group in accordance with the Statement of Recommended Practice ('SORP') issued by the Association of Investment Companies ("AIC") in July 2022.

The Financial Statements are prepared on the historical cost basis, except for the revaluation of financial instruments measured at fair value through profit or loss.

Fair value is the price that would be received on sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, regardless of whether that price is directly observable or estimated using another valuation technique. In estimating the fair value of an asset or liability, the Company and Group take into account the characteristics of the asset or liability if market participants would take those characteristics into account when pricing the asset or liability at the measurement date. Fair value for measurement and/or disclosure purposes in these Financial Statements is determined on such a basis.

The Financial Statements are presented in Pounds Sterling because that is the currency of the primary economic environment in which the Company and Group operate.

The principal accounting policies adopted are set out below. These policies are consistently applied.

Accounting for subsidiaries

The Board of Directors has determined that the Company has all the elements of control as prescribed by IFRS 10 in relation to:

1. the Limited Partnership; as the Company is the sole limited partner in the Limited Partnership (100% of the Limited Partnership's commitments are held by the Company), is exposed to and has rights to the returns of the Limited Partnership, and has the ability through its control of the General Partner to affect the amount of its returns from the Limited Partnership; and

2. the General Partner; as the Company wholly owns the General Partner, is exposed to and has rights to the returns of the General Partner and has the ability through its control of the General Partner's activities to affect the amount of its returns from the General Partner.

The Investment entities exemption requires that an investment entity that has determined that it is a parent under IFRS 10 shall not consolidate certain of its subsidiaries; instead, it is required to measure its investment in these subsidiaries at fair value through profit or loss in accordance with IFRS 9. The criteria which define an investment entity are as follows:

(i) the company obtains funds from one or more investors for the purpose of providing those investors with investment management services;

(ii) the company commits to its investors that its business purpose is to invest funds solely for returns from capital appreciation, investment income, or both; and

(iii) the company measures and evaluates the performance of substantially all of its investments on a fair value basis.

The Company is an investment company, providing investors exposure to a diversified portfolio of hydrogen and complementary hydrogen focused assets that are managed for investment purposes. The investments were made in line with the stated objective of the Company to deliver an attractive level of capital growth in accordance with the strategy that has been set by the Directors.

In assessing whether the Company meets the definition of an investment entity set out in IFRS 10 the Directors' note that:

(i) the Company has multiple investors with shares issued publicly on the London Stock Exchange and obtains funds from a diverse group of shareholders who would otherwise not have access individually to investing in hydrogen focussed assets;

(ii) the Company's purpose is to invest funds for capital appreciation but with potential for some investment income. The Limited Partnership has a ten-year life however the underlying assets have minimal residual value because they do not have unlimited lives, are not to be held indefinitely and have appropriate exit strategies in place; and

(iii) the Company measures and evaluates the performance of all of its investments on a fair value basis which is the most relevant for investors in the Company. The Directors use fair value information as a primary measurement to evaluate the performance of all of the investments and in decision making.

The Directors assess each new investment carefully to determine whether the Company as a whole continues to meet the definition of an investment entity.

The Board of Directors has determined that the Company meets all the typical characteristics of an investment entity and therefore meets the definition set out in IFRS 10.

Accounting for the Limited Partnership

The Limited Partnership serves as an asset holding entity and does not provide investment-related services. Therefore, when the Limited Partnership is assessed based on the overall structure as a means of carrying out the Company's activities, the Board of Directors has determined that the Limited Partnership meets the definition of an investment entity. Accordingly, the Company is required under IFRS 10 to hold its investment in the Limited Partnership at fair value through the Statement of Comprehensive Income rather than consolidate them. The Company has determined that the fair value of the Limited Partnership is its net asset value and has concluded that it meets the definition of an unconsolidated subsidiary under IFRS 12 and has made the necessary disclosures in these Financial Statements.

Accounting for the General Partner

The Directors agree that the investment entity accounting treatment outlined above appropriately reflects the Company's activities as an investment trust and provides the most relevant information to investors.

Going concern

The Directors consider that it is appropriate to adopt the going concern basis in preparing the Financial Statements. In reaching this conclusion, the Directors considered the income and expense projections and the liquidity of the investment portfolio, and considered the impact to the Company and portfolio of investments from the economic conditions such as higher interest rates and inflationary pressures and market volatility arising from the ongoing wars in Ukraine and the Middle East.

The Company and Group continue to meet day-to-day liquidity needs through its cash resources. The Company and Group had at 31 December 2023 unrestricted cash of £4.6 million (2022: £18.2 million) as well as £2.3 million (2022: £3.7 million) in Listed Hydrogen Assets. The Company and Group's net assets at 31 December 2023 were £132.7 million (2022: £125.4 million) and total expenses for the year ended 31 December 2023 were £2.0 million (2022: £1.7 million), which represented approximately 1.5% (2022: 1.5%) of the average net assets value of the Company in the year to 31 December 2023 of £129.4 million (2022: £116.8 million).

At the date of approval of these Financial Statements, the Company and Group had cash resources of £4.0 million and annual expenses are estimated to be £3.6 million.

The Directors also recognise that the continuation of the Company is subject to the approval of shareholders at the Annual General Meeting ("AGM") in 2026, and every fifth AGM thereafter. The Board has considered the long term prospects of the Company and has no reason to believe that the continuation vote will fail.

Based on the foregoing, the Directors have adopted the going concern basis in preparing the Financial Statements. The Directors have a reasonable expectation that the Company and Group have adequate operational resources to continue in operational existence for at least twelve months from the date of approval of these Financial Statements.

Critical accounting judgements, estimates and assumptions

The preparation of Financial Statements in accordance with IFRS requires the Directors to make judgements, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Financial Statements and the reported amounts of income and expense during the period. Actual results could differ from those estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised if the revision only affects that period or in the period and future periods if the revision affects both current and future periods.

Judgements

Investment entity

In accordance with the Investment Entities exemption contained in IFRS 10, the Board has determined that the Company satisfies the criteria to be regarded as an investment entity and that the Company provides investment related services and, as a result, measures its investment in the Limited Partnership at fair value.

The General Partner provides investment related services to the Limited Partnership on behalf of the Company. IFRS 10 requires subsidiaries that provide services that relate to the investment entity's investment activities to be consolidated. Accordingly, the Board of Directors have determined that the Company is required under IFRS 10 to consolidate the results of the General Partner. As described in the Reporting Entity section, the Financial Statements as presented represent both the Parent's and the Group's financial position, performance and cash flows.

These conclusions involved a degree of judgement and assessment as to whether the Company, the Limited Partnership and the General Partner met the criteria outlined in the accounting standards.

Estimates

Investment valuations

The key estimate in the Financial Statements is the determination of the fair value of the Private Hydrogen Assets, held by the Limited Partnership, by the Investment Adviser for consideration by the Directors. This estimate is key as it significantly impacts the valuation of the Limited Partnership at the year end. The fair valuation process involves estimation using subjective inputs that are unobservable (for which market data is unavailable). The key inputs considered in the valuation are described in note 15.

New standards, interpretations and amendments adopted from 1 January 2023

Effective in the current financial year

The Board have assessed those new standards, interpretations, and/or amendments which became effective during the financial year under review and concluded they have no material impact to the Company.

New standards and amendments issued but not yet effective

The relevant new and amended standards and interpretations that are issued, but not yet effective, up to the date of issuance of the financial statements are disclosed below.

The Board have assessed new but not yet effective standards applicable to the Company and have concluded that they will not have a material impact to the Company.

3. Material accounting policies

(a) Financial instruments

Financial assets - Classification, recognition, derecognition and measurement

The Company and Group's financial assets principally comprise of: investments held at fair value through profit or loss (Listed Hydrogen Assets and the Limited Partnership); and trade and other receivables, which are initially recognised at fair value and subsequently measured at amortised cost.

Financial assets are recognised in the Statement of Financial Position when the Company or Group become a party to the contractual provisions of the instrument. Transaction costs that are directly attributable to the acquisition or issue of financial assets (other than financial assets at fair value through profit or loss) are added to or deducted from the fair value of the financial assets, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets at fair value through profit or loss are recognised immediately in profit or loss.

Subsequent to initial recognition, financial assets at fair value through profit or loss are measured at fair value. Gains and losses resulting from the movement in fair value are recognised in the Statement of Comprehensive Income at each valuation point within 'gains/(losses) on investments'.

Financial assets are derecognised when the rights to receive cash flows from the investments have expired or the Company or Group have transferred substantially all risks and rewards of ownership.

Financial liabilities - Classification, recognition, derecognition and measurement

The Company and Group's financial liabilities include trade and other payables and other short term monetary liabilities which are initially recognised at fair value and subsequently measured at amortised cost.

Financial liabilities are recognised in the Statement of Financial Position when the Company or Group become a party to the contractual provisions of the instrument. Transaction costs that are directly attributable to the acquisition or issue of financial liabilities (other than financial liabilities at fair value through profit or loss) are added to or deducted from the fair value of the financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial liabilities at fair value through profit or loss are recognised immediately in profit or loss. Financial liabilities are subsequently measured at amortised cost.

A financial liability (in whole or in part) is derecognised when the Company or Group have extinguished the contractual obligations, it expires or is cancelled.

Valuation of Listed Hydrogen Assets

Upon initial recognition Listed Hydrogen Assets are classified by the Company and Group 'at fair value through profit or loss'. They are accounted for on the date they are traded and are included initially at fair value which is taken to be their cost. Subsequently they are valued at fair value, which is the bid market price, or if bid price is unavailable, last traded price on the relevant exchange.

Valuation of the Limited Partnership

The Company may make investments in Private Hydrogen Assets directly, via the Limited Partnership and/or by way of holdings in special purpose vehicles or intermediate holding entities. Currently, all the Company's Private Hydrogen Assets are held via the Limited Partnership.

The Company and Group has determined that the fair value of the Limited Partnership is the Limited Partnership's Net Asset Value ("NAV"). The NAV of the Limited Partnership is prepared in accordance with accounting policies that are consistent with IFRS and consists of the fair value of its Private Hydrogen Assets, and the carrying value of its assets and liabilities.

The Investment Adviser values the Private Hydrogen Assets according to IPEV Guidelines. The valuation techniques available under IPEV Guidelines are set out below and are followed by an explanation of how they are applied to the Private Hydrogen Assets:

· Discounted cash flows ("DCF");

· Price of recent investment;

· Multiples;

· Industry Valuation Benchmarks;

· Available Market Prices; and

· Net Assets

The nature of the Private Hydrogen Assets will influence the valuation technique applied. The valuation approach recognises that, as stated in the IPEV Guidelines, the price of a recent investment, if resulting from an orderly transaction, generally represents fair value as at the transaction date and may be an appropriate starting point for estimating fair value at subsequent measurement dates. Consideration is given to the facts and circumstances as at the subsequent measurement date such as changes in the market or performance of the investee company including whether maintainable revenues and/ or earnings have been established. Milestone analysis is used, where appropriate, to incorporate the operational progress of the investee company into the valuation.

As a result, various techniques may be employed to derive the valuations. However, an absence of relevant industry peers may preclude the application of the industry valuation benchmarks technique and an absence of observable prices may preclude the available market prices approach. All valuations are calibrated and are cross-checked for reasonableness by employing relevant alternative techniques.

Private Hydrogen Assets, which are operational companies, are valued using either the price of recent investment; the DCF method; or a combination of the DCF method and the price of recent investment. The valuations are weighted towards the DCF method based on the time since the price of recent investment until the full DCF valuation is applied (typically the valuations are tapered from the price of recent investment to the full DCF valuation over four calendar quarters after the price of recent investment). The impact of this weighted approach is that there will be either an effective discount or a premium to the full DCF valuation over the tapering period. The valuations derived from this approach have been assessed for reasonableness against relevant market comparables, where available, and calibrated against specific milestones for indications of positive or negative performance which may impact valuations. Where negative performance indicates that the valuation of a Private Hydrogen Asset may have deteriorated substantially then alternative valuation approaches may be incorporated into the valuation model that reflect reasonable possible outcomes, such as net assets and indicative offers, and a probability weighting is applied to each.

Private Hydrogen Assets, which are hydrogen project SPVs, are valued based on the underlying project's stage of completion:

· prior to commercial operation date, hydrogen project SPVs are valued using a risk adjusted DCF method;

· post commercial operation date, hydrogen project SPVs are valued in the same way as Private Hydrogen Assets, which are operational companies, as described above; and

· project development loans advanced directly by the Limited Partnership to a project during the project development phase are held at cost plus accrued interest (deemed to approximate fair value), and are reviewed at each valuation date for any indicators that this approach may no longer be representative of fair value.

In a DCF valuation, the fair value represents the present value of the investment's expected future cash flows, based on appropriate assumptions for revenues and costs, and suitable cost of capital assumptions. Judgement is applied in arriving at appropriate discount rates, based on the knowledge of the market, taking into account market intelligence gained from bidding activities, discussions with financial advisers, consultants, accountants and lawyers and publicly available information.

A range of sources are reviewed in determining the underlying assumptions to apply in a DCF valuation used in calculating the fair value of a Private Hydrogen Asset. These sources include but are not limited to:

· macroeconomic projections adopted by the market as disclosed in publicly available resources;

· macroeconomic forecasts provided by expert third party economic advisers;

· discount rates publicly disclosed in the global renewables sector;

· discount rates applicable to comparable infrastructure asset classes, which may be procured from public sources or independent third-party expert advisers;

· discount rates publicly disclosed for comparable market transactions of similar assets; and

· capital asset pricing model outputs and implied risk premia over relevant risk-free rates. Where available, assumptions are based on observable market and technical data.

(b) Foreign currency

Functional and presentation currency

Items included in the Financial Statements are measured using the currency of the primary economic environment in which the entity operates, the functional currency. The Financial Statements are presented in Pounds Sterling which is the Company and Group's functional and presentation currency.

Transactions and balances

Foreign currency transactions are translated into Pounds Sterling using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in the Statement of Comprehensive Income.

Dividend income has been accounted for on an ex-dividend basis or when the right to the income is established. Investment interest income for the year is recognised in the Statement of Comprehensive Income using effective interest method calculation. Bank interest income is recognised for the year in the Statement of Comprehensive income on a receipts basis. Special dividends are credited to capital or revenue in the Statement of Comprehensive Income, according to the circumstances surrounding the payment of the dividend. Overseas dividends are included gross of withholding tax recoverable.

(d) Dividend payable

Interim dividends are recognised when the Company pays the dividend. Final dividends are recognised in the period in which they are approved by the shareholders.

(e) Expenses

All expenses are accounted for on an accruals basis. Expenses directly related to the acquisition or disposal of an investment (transaction costs) are taken to the Statement of Comprehensive Income as a capital item. All other expenses, including Investment Adviser fees, are taken to the Statement of Comprehensive Income as a revenue item.

(f) Taxation

The tax expense represents the sum of the tax currently payable and deferred tax. The tax currently payable is based on the taxable profit for the period. Taxable profit differs from net profit as reported in the Statement of Comprehensive Income because it excludes items of income or expenses that are taxable or deductible in other years and it further excludes items that are never taxable or deductible. The Company's liability for current tax is calculated using tax rates that were applicable at the financial reporting date.

Where expenses are allocated between capital and revenue any tax relief in respect of the expenses is allocated between capital and revenue returns on the marginal basis using the Company's effective rate of corporation taxation for the relevant accounting period.

Deferred taxation is recognised in respect of all timing differences that have originated but not reversed at the financial reporting date, where transactions or events that result in an obligation to pay more tax in the future or right to pay less tax in the future have occurred at the financial reporting date. This is subject to deferred tax assets only being recognised if it is considered more likely than not that there will be suitable profits from which the future reversal of the timing differences can be deducted. Deferred tax assets and liabilities are measured at the rates applicable to the legal jurisdictions in which they arise.

Since the General Partner does not have any income or expenditure in the period, the Group tax position is the same as the Company tax position.

(g) Segmental reporting

The Board has considered the requirements of IFRS 8 - 'Operating Segments'. The Company has entered into an Investment Advisory Agreement with the Investment Adviser under which the Investment Adviser is responsible for the management of the Company's investment portfolio, subject to the overall supervision of the Board of Directors. Subject to its terms and conditions, the Investment Advisory Agreement requires the Investment Adviser to manage the Company's investment portfolio in accordance with the Company's investment guidelines as in effect from time to time, including the authority to purchase and sell investments and to carry out other actions as appropriate to give effect thereto. However, the Board retains full responsibility to ensure that the Investment Adviser adheres to its mandate. Moreover, the Board is fully responsible for the appointment and/or removal of the Investment Adviser. Accordingly, the Board is deemed to be the 'Chief Operating Decision Maker' of the Company.

The Directors are of the opinion that the Company is engaged in a single segment of business being investment into the hydrogen focussed investments. Segment information is measured on the same basis as that used in the preparation of the Company's Financial Statements.

(h) Cash and cash equivalents

Cash comprises cash and demand deposits. Cash equivalents, include bank overdrafts, and short-term, highly liquid investments that are readily convertible to known amounts of cash, are subject to insignificant risks of changes in value, and are held for the purpose of meeting short-term cash commitments rather than for investment or other purposes.

(i) Nature and purpose of equity and reserves:

Share capital represents the 1p nominal value of the issued share capital.

The share premium account arose from the net proceeds of new shares issued. Costs directly attributable to the issue of new shares are charged against the value of the ordinary share premium.

The capital reserve reflects any:

· gains or losses on the disposal of investments;

· exchange movements of a capital nature;

· the increases and decreases in the fair value of investments which have been recognised in the capital column of the Statement of Comprehensive Income; and

· expenses which are capital in nature.

The revenue reserve reflects all income and expenditure recognised in the revenue column of the Statement of Comprehensive Income and is distributable by way of dividend.

The Company's distributable reserves consist of the revenue reserve and the capital reserve. However any gains in the fair value of investments that are not readily convertible to cash are treated as unrealised gains in the capital reserve and are non-distributable.

Ordinary Shares are classified as equity.

Under IFRS 13 'Fair Value Measurement', an entity is required to classify investments using a fair value hierarchy that reflects the significance of the inputs used in making the measurement decision.

The following shows the analysis of financial assets recognised at fair value based on:

Level 1

The unadjusted quoted price in an active market for identical assets or liabilities that the entity can access at the measurement date.

Level 2

Inputs other than quoted prices included within Level 1 that are observable (i.e. developed using market data) for the asset or liability, either directly or indirectly.

Level 3

Inputs are unobservable (i.e. for which market data is unavailable) for the asset or liability.

Transfers between levels of the fair value hierarchy are recognised as at the end of the reporting period during which the change has occurred. There have been no transfers between levels during the year ended 31 December 2023 (2022: no transfers).

The classification of the Company and Group's investments held at fair value through profit or loss is detailed in the table below:

	31 December 2023
	Level 1 £'000	Level 2 £'000	Level 3 £'000	Total £'000
Listed Hydrogen Assets	2,322	-	-	2,322

Limited Partnership	-	-	103,006	103,006
	3,667	-	103,006	106,673

The Company and Group's Level 3 investment is the investment in the Limited Partnership. The NAV of the Limited Partnership as of 31 December 2023 is £125,861,000 (2022: £103,006,000). The movement on the Level 3 investments during the year is shown below:

	31 December 2023 £'000	31 December 2022 £'000
Opening balance	103,006	60,597
Investment in Limited Partnership	12,398	36,581
Movement in unrealised gains on investment in Limited Partnership	10,457	5,828
Closing balance	125,861	103,006

Look-through financial information

The NAV of the Limited Partnership consists of the fair value of its Private Hydrogen Assets and the carrying value of its assets and liabilities. As at the year end, the Limited Partnership held ten Private Hydrogen Assets (2022: nine).

The following table reconciles the fair value of the Private Hydrogen Assets and the NAV of the Limited Partnership.

The Level 3 Private Hydrogen Assets are valued by the Investment Adviser using the valuation techniques as outlined in note 3. The key inputs considered in the valuation are described in note 15.

At 31 December 2023, the valuations of the Limited Partnership's underlying investments in Private Hydrogen Assets were determined as follows:

Name	Country of Incorporation	Value of Investment £'000	Primary valuation technique	Significant unobservable inputs	Range input
Sunfire GmbH	Germany	27,068	DCF	Discount rates	11.3%-12.4%
Elcogen Group plc	United Kingdom	24,430	DCF	Discount rates	13.1%-13.9%

HH2E Werk Thierbach GmbH	Germany	1,955	Loan principal and accrued interest	N/a	N/a

At 31 December 2022, the valuation of the Limited Partnership's underlying investment in Private Hydrogen Assets was determined as follows.

Name	Country of Incorporation	Value of Investment £'000	Primary valuation technique	Significant unobservable inputs	Range input
Sunfire GmbH	Germany	21,763	Weighted DCF and Price of Recent Investment	Discount rates applied in full DCF valuation	12.1% - 12.4%
				Weighting between Price of Recent Investment and DCF valuation¹	(4)%
Elcogen Group plc	United Kingdom	20,430	Weighted DCF and Price of Recent Investment	Discount rates applied in full DCF valuation	12.5% - 13.0%
				Weighting between Price of Recent Investment and DCF valuation¹	4%

* In deriving the fair value of NanoSUN a probability weighted approach was applied whereby a valuation for the investment was derived from each technique (DCF, indicative offers and assets), each of which represented management's assessment of the fair value for the investment in the reasonable possible scenarios that may have transpired, as of the valuation date. A percentage likelihood (aggregating to 100% across each of the three techniques) was then applied to each of these valuations, which represented management's view of the probability of each scenario transpiring, as of the valuation date. The range of inputs disclosed represent the lowest and highest discreet percentages applied to the three scenarios.

Name	Country of Incorporation	Value of Investment £'000	Primary valuation technique	Significant unobservable inputs	Range input
Strohm Holding BV	Netherlands	11,606	Weighted DCF and Price of Recent Investment	Discount rates applied in full DCF valuation	12.5% - 12.8%
				Weighting between Price of Recent Investment and DCF valuation¹	(31)%
HiiROC Limited	United Kingdom	12,914	DCF	Discount rates	13.5%
Cranfield Aerospace Solutions Limited	United Kingdom	6,296	Weighted DCF and Price of Recent Investment	Discount rates applied in full DCF valuation	13.5%
				Weighting between Price of Recent Investment and DCF valuation¹	(20)%
Bramble Energy Limited	United Kingdom	10,032	Weighted DCF and Price of Recent Investment	Discount rates applied in full DCF valuation	13.4% - 13.6%
				Weighting between Price of Recent Investment and DCF valuation¹	24%
HH2E AG	Germany	5,134	Weighted DCF and Price of Recent Investment	Discount rates applied in full DCF valuation	12.1% - 12.4%
				Weighting between Price of Recent Investment and DCF valuation¹	6%
NanoSUN Limited	United Kingdom	11,519	Weighted DCF and Price of Recent Investment	Discount rates applied in full DCF valuation	13.4% - 13.6%
				Weighting between Price of Recent Investment and DCF valuation¹	(10)%
GEN2 Energy AS	Norway	3,421	Weighted DCF and Price of Recent Investment	Discount rates applied in full DCF valuation	13.0%
				Weighting between Price of Recent Investment and DCF valuation¹	(10)%

1. This is the effective discount or premium to the full DCF valuation, as a result of application of the weighted valuation in line with the valuation methodology described in note 3. A negative percentage denotes that the weighted valuation is at a discount to the full DCF valuation; whilst a positive percentage denotes that the weighted valuation is at a premium to the full DCF valuation.

The following table shows the Directors best estimate of the sensitivity of the Level 3 Private Hydrogen Assets to changes in the principle unobservable input, with all other variables held constant.

	Effect on fair value of investments £'000
Unobservable input	Possible reasonable change in input	31 December 2023	31 December 2022
Discount rates applied in full DCF valuation	+1%	(7,767)	(6,515)
	-1%	8,584	7,815
Weighting between DCF, indicative offers and Net Asset valuation	+/- 10% weighting to DCF	968/(968)	n/a
	+/- 10% weighting to indicative offers	124/(124)	n/a
	+/- 10% weighting to Net Assets	1,092/(1,092)	n/a
Weighting between Price if Recent Investment and full DCF Valuation	Plus one calendar quarter of tapering from Price of Recent Investment to full DCF valuation	n/a	(324)
	Minus one calendar quarter of tapering from Price of Recent Investment to full DCF valuation	n/a	286

The European Central Bank ('ECB') and the Bank of England ('BOE') base rates at 31 December 2023 were 4.5% and 5.25% respectively. We anticipate that the base rates will ease and fall (based on independent research) reaching 2.50% for ECB and 3.00% for BOE by end of 2025. Since long term gilt yields already factor in long term forecasts, we have performed sensitivities of +/- 1% on the discount rate assumptions for any shock events. At 31 December 2022, the ECB and the BOE base rates were 2.5% and 3.5% respectively. We anticipated that the terminal base rate hikes (based on independent research) could reach 3.75% for ECB and 4.75% for BOE and as such, performed sensitivities of +/- 1% on the discount rate assumptions.

For the year ended 31 December 2023, the NanoSUN Limited valuation is weighted between DCF, indicative offers and Net assets based on the expected likelihood of each scenario occurring. We have applied a sensitivity of +/- 10% weighting to each scenario, with the movement being shared equally with the remaining two scenarios, as this is deemed to be a reasonable possible shift in the scenario weightings as of the valuation date.

For the year ended 31 December 2022, the valuations are weighted towards the full DCF valuation based on the time since the price of recent investment until the full DCF valuation is applied (typically the valuations are tapered from the price of recent investment to the full DCF valuation over four calendar quarters after the price of recent investment). Accordingly, we have applied a sensitivity of +/- one calendar quarter of this weighting as this is deemed the most likely period by which the tapering may be delayed or brought forward.

For those investments that have been fair valued using the price of a recent investment based on unadjusted third-party pricing information and project development loans held at cost plus accrued interest, the Company is not required to disclose any quantitative information regarding the unobservable inputs as they have not been developed by the Company and are not reasonably available to the Company.

At 31 December 2023, £nil in respect of excess IPO issue costs is due to be received from the Investment Adviser (2022: £111,432).

Investment Adviser fee

The Company has entered into an Investment Adviser Agreement dated 5 July 2021 between the Company, the AIFM and the Investment Adviser (the "Investment Adviser Agreement"), pursuant to which the Investment Adviser has been given responsibility for investment advisory services in respect of any Private Hydrogen Assets the Company invests in directly and the Listed Hydrogen Assets (including Listed Hydrogen Assets forming part of the Liquidity Reserve and uninvested cash) in accordance with the Company's investment policy, subject to the overall control and supervision of the AIFM.

Under the Investment Adviser Agreement, the Investment Adviser receives from the Company, quarterly in advance, an advisory fee equal to:

i. 1.0% of the Net Asset Value per annum of the Listed Hydrogen Assets up to £100 million:

ii. 0.8% of the Net Asset Value per annum of the Listed Hydrogen Assets from £100 million (save that the Investment Adviser has agreed to reduce this fee to 0.5% in respect of the Liquidity Reserve pending their investment in Private Hydrogen Assets for 18 months following Admission to 30 January 2023);

iii. 1.5% of the Net Asset Value per annum of any Private Hydrogen Assets held by the Company directly (i.e. not held by the Limited Partnership or any other undertaking advised by the Investment Adviser where the Investment Adviser is receiving a separate advisory fee); and

iv. for so long as the Company is not considered a 'feeder fund' for the purposes of the Listing Rules, 1.5% per annum of the Net Asset Value of the Private Hydrogen Assets held by the Limited Partnership.

The Limited Partnership has entered into a Limited Partnership Investment Adviser Agreement dated 5 July 2021 (the "Limited Partnership Investment Adviser Agreement") between the General Partner (in its capacity as general partner of the Limited Partnership), the AIFM and the Investment Adviser, pursuant to which the Investment Adviser has been given responsibility for investment advisory services in respect of the Private Hydrogen Assets in accordance with the investment policy of the Limited Partnership, subject to the overall control and supervision of the AIFM.

Under the Limited Partnership Investment Adviser Agreement, the Investment Adviser, if the Company was considered a 'feeder fund' for the purposes of the Listing Rules by virtue of additional investors co-investing via the Limited Partnership in the future, shall receive from the Limited Partnership an advisory fee equal to 1.5% per annum of the Net Asset Value of the Private Hydrogen Assets held by the Limited Partnership, payable quarterly in advance. Advisory fees paid or payable by the Limited Partnership are reflected through the NAV of the Limited Partnership.

No performance fee is paid or payable to the Investment Adviser under either the Investment Adviser Agreement or the Limited Partnership Investment Adviser Agreement but the principals of the Investment Adviser are, subject to certain performance conditions being met, entitled to carried interest fees from the Limited Partnership. Refer to 'Carried Interest Partner Fees' section below.

Carried Interest Partner Fees

Pursuant to the terms of the Limited Partnership Agreement dated 5 July 2021 as amended and restated on 26 November 2021 (the "Limited Partnership Agreement"), the Carried Interest Partner is, subject to the limited partners of the Limited Partnership receiving an aggregate annualised 8% realised return (i.e. the Company and, in due course, any additional co-investors), entitled to a carried interest fee in respect of the performance of the Private Hydrogen Assets.

Subject to certain exceptions, the Carried Interest Partner will receive, in aggregate, 15% of the net realised cash profits from the Private Hydrogen Assets held by the Limited Partnership once the limited partners of the Limited Partnership (i.e. the Company and, in due course, any additional co-investors) have received an aggregate annualised 8% realised return. This return is subject to a 'catch-up' provision in Carried Interest Partner's favour. Any realised or unrealised carried interest fee paid or payable to the Carried Interest Partner is reflected through the NAV of the Limited Partnership. As at 31 December 2023, in the Limited Partnership, there is unrealised carried interest fee payable of £403,343 (year to 31 December 2022: £nil).

20% of any carried interest received (net of tax) will be used by the principals of the Investment Adviser to acquire Ordinary Shares in the market. Any such acquired shares will be subject to a 12-month lock-up from the date of purchase.

General Partner's priority profit share

Under the Limited Partnership Agreement, the General Partner of the Limited Partnership shall be entitled to a General Partner's Profit Share ("GPS"). The GPS for each accounting period shall be an amount equal to 1.5% of the prevailing NAV of the Limited Partnership. For so long as the Company is the sole limited partner of the Limited Partnership, the GPS shall be distributed to the Company rather than the General Partner. The Company is currently the sole limited partner of the Limited Partnership. Therefore, under the Investment Adviser Agreement, the investment adviser fee in relation to the Private Hydrogen Assets held by the Limited Partnership is settled by the Company which for the year totalled £1,723,369 (31 December 2022: £1,181,069). During the year the Limited Partnership did not call any GPS from the Company as the net effect of the calling and distributing GPS from/to the Company is £nil (31 December 2022: £nil).

During the year, no non-audit service fees were paid.

Costs of £500,000, incurred during the year ended 31 December 2022, applicable to the share issuance Circular and Prospectus published in September 2022 (the "share issuance Circular and Prospectus"), which were recognised as trade and other receivables as at 31 December 2022, were released from trade and other receivables to abort costs in the Statement of Comprehensive Income for the year ended 31 December 2023 as no shares had been issued at the Circular and Prospectus expiry date in September 2023. These costs included non-audit service costs applicable to the share issuance Circular and Prospectus (KPMG UK LLP received £42,000 which was inclusive of VAT of £7,000).

During the year to 31 December 2022, where non-audit services were carried out in relation to a further secondary share issuance that was aborted, the costs (KPMG received £75,000; and KPMG UK LLP received £108,000 which was inclusive of VAT of £18,000) were treated as a capital expense (abort costs) disclosed in the Statement of Comprehensive Income

Each of these non-audit services provided during the year to 31 December 2022 were required by law or regulation and were therefore permissible non-audit services under the FRC Ethical Standard.

Total tax charge	-	-	-	-	-	-

The Company is not liable to tax on capital gains due to its status as an investment trust. The Company and Group has an unrecognised deferred tax asset of £963,000 (2022: £600,000) as a result of excess management expenses of £3,853,000 (2022: 2,400,000), based on the long term prospective corporation tax rate of 25%.

This asset has accumulated because deductible expenses exceeded taxable income for the year ended 31 December 2023 and prior periods. No asset has been recognised in the Financial Statements because, given the composition of the Company and Group's portfolio, it is not likely that this asset will be utilised in the foreseeable future.

At 31 December 2022 other receivables included £470,000 in respect of costs applicable to the share issuance Circular and Prospectus (£470,000) published in September 2022 and expiring in September 2023. These costs were reclassified as abort costs in the Statement of Comprehensive Income in 2023 as no shares had been issued at the Circular and Prospectus expiry date.

Closing balance as at 31 December	128,819,999	1,288,199.99	128,819,999	1,288,199.99

The Company is permitted to hold Ordinary Shares acquired by way of market purchase in treasury, rather than having to cancel them. Such Ordinary Shares may be subsequently cancelled or sold for cash. No Ordinary Shares have been repurchased during the year therefore there were no Treasury shares at the end of the year.

Each Ordinary Share held entitles the holder to one vote. All shares carry equal voting rights and there are no restrictions on those voting rights.

Costs applicable to the share issuance Circular and Prospectus issued in September 2022 totaling £500,000 were treated as an other debtor at 31 December 2022 (£470,000) or accrued during the year (£30,000). These costs were reclassified as abort costs in the Statement of Comprehensive Income for the year ended 31 December 2023 as no shares had been issued at the Circular and Prospectus expiry date in September 2023.

12. Return per ordinary share

Return per share is based on the weighted average number of Ordinary Shares in issue during the year ended 31 December 2023 of 128,819,999 (2022: 122,878,985).

	Year ended 31 December 2023			Year ended 31 December 2022

15. Financial instruments and capital disclosures

Risk Management Policies and Procedures

The Board of Directors has overall responsibility for the establishment and oversight of the Company and Group's risk management framework. The risk management policies are established to identify and analyse the risks faced by the Company and Group, to set appropriate risk limits and controls and to monitor risks and adherence to limits. Risk management policies are reviewed regularly to reflect changes in market conditions and the Company and Group's activities.

The Investment Adviser, AIFM and the Administrator report to the Board on a quarterly basis and provide information to the Board which allows it to monitor and manage financial risks relating to its operations. The Company and Group's activities expose it to a variety of financial risks: market risk (including currency risk, interest rate risk and price risk), credit risk, liquidity risk and operational risk. These risks are monitored by the AIFM. Below is a non-exhaustive summary of the risks that the Company and Group are exposed to as a result of its use of financial instruments:

The objectives, policies and processes for managing the risks, and the methods used to measure the risks, are set out below:

Market Risks

(i) Currency risk

Foreign currency risk is defined as the risk that the fair values of future cashflows will fluctuate because of changes in foreign exchange rates. The financial assets and liabilities are predominantly denominated in Pounds Sterling and substantially all revenues and expenses are in Pounds Sterling. As at the 31 December 2023 and 31 December 2022, the Company and Group had the following currency exposures, all of which are included in the Statement of Financial Position at fair value based on the exchanges rates at the year end.

	31 December 2023				31 December 2022
	Investments	Cash	Other assets & liabilities	Total	Investments	Cash	Other assets & liabilities	Total
Currency	£'000	£'000	£'000	£'000	£'000	£'000	£'000	£'000
Danish Krone	180	-	-	180	132	-	-	132
Euro	806	-	-	806	1,246	-	-	1,246
Korean Won	501	-	-	501	667	-	-	667
Norwegian Krone	259	-	-	259	609	-	-	609
Swedish Krona	3	-	-	3	230	-	-	230
US Dollar	213	-	-	213	344	-	-	344
	1,962	-	-	1,962	3,228	-	-	3,228

The Company and Group mitigate the risk of loss due to exposure to a single currency by way of diversification of the portfolio. The Limited Partnership's non Pound Sterling denominated assets may have currency exposure hedged by Forward Exchange Contracts so that impact from currency exchange rate movements would be mitigated. At 31 December 2023, the Company and Group have not hedged the value of non-Pound Sterling denominated investments. This increases foreign currency risk and may increase volatility of the Company and Group's net asset value. At 31 December 2022, the Limited Partnership's non Pound Sterling denominated assets had currency exposure hedged by Forward Exchange Contracts so that the impact from currency exchange rate movement was mitigated.

At 31 December 2023, an exchange rate movement of +/-5% against Pounds Sterling, which is a reasonable approximation of possible changes based on observed volatility during the year, would have increased or decreased net assets and total return by £98,100 (2022: £161,400).

(ii) Interest rate risk

The Company and Group's interest rate risk on interest bearing financial assets is limited to interest earned on cash balances. At the year end, the Company and Group had cash balances of £4,626,000 (£2022: £18,192,000). An increase in interest rates of 2.0%, which is reasonable based upon changes in interest rates observed in the year, would impact the profit or loss and net assets of the Company and Group positively by £92,520, with a decrease of 2.0% having an equal and opposite effect (2022: an increase or decrease of 3% would have had a positive or negative affect of £545,760).

The Company and Group's interest and non-interest bearing assets and liabilities as at 31 December 2023 and 31 December 2022 are summarised below:

	31 December 2023			31 December 2022
	Interest bearing £'000	Non-interest bearing £'000	Total £'000	Interest bearing £'000	Non-interest bearing £'000	Total £'000

Trade and other payables	-	(190)	(190)	-	(153)	(153)
Total liabilities	-	(190)	(190)		(153)	(153)

(iii) Price risk

Listed Hydrogen Assets

Price risk is defined as the risk that the fair value of a financial instrument held by the Company or Group will fluctuate. Listed Hydrogen Assets are measured at fair value through profit or loss. As of 31 December 2023, the Company and Group held Listed Hydrogen Assets with an aggregate fair value of £2,322,000 (2022: £3,667,000).

All other things being equal, the effect of a 10% increase or decrease in the value of the investments held at the year end would have been an increase or decrease of £232,200 in the Company and Group's loss after taxation for the year ended 31 December 2023 and the Company and Group's net assets at 31 December 2023 (2022: £366,700).

At 31 December 2023, the sensitivity rate of 10% is regarded as reasonable due to the actual market price volatility experienced as a result of the economic impact on the Listed Hydrogen Assets.

Private Hydrogen Assets

The Limited Partnership's portfolio of Private Hydrogen Assets is not necessarily affected by market performance, however the valuations may be affected by the performance of the underlying investments in line with the valuation criteria in note 3.

The Private Hydrogen Assets sensitivity analysis in note 4 recognises that the valuation methodologies employed involve different levels of subjectivity in their inputs primarily driven by changes in discount rate assumptions and weighting of the techniques employed.

Key variable inputs of Private Hydrogen Assets

The variable inputs applicable to each broad category of valuation basis will vary depending on the particular circumstances of each Private Hydrogen Asset valuation. An explanation of each of the key variable inputs is provided below and includes an indication of the range in value for each input, where relevant.

Selection of appropriate discount rates

The selection of an appropriate discount rate is assessed individually for each Private Hydrogen Asset. Publicly disclosed discount rates in the relevant sector and comparable asset classes, which may be procured from public sources or independent third-party expert advisers or for comparable market transactions of similar assets are used where available.

Selection of appropriate benchmarks

The selection of appropriate benchmarks is assessed individually for each Private Hydrogen Asset. The industry and geography of each Private Hydrogen Asset are key inputs to the benchmark selection, with either one or two key indices or benchmarks being used for comparison.

Selection of comparable companies

The selection of comparable companies is assessed individually for each Private Hydrogen Asset at the point of investment, and the relevance of the comparable companies is continually evaluated at each valuation point. The key criteria used in selecting appropriate comparable companies are the industry sector in which they operate and the geography of the Private Hydrogen Asset's operations.

Application of valuation basis

Each Private Hydrogen Asset is assessed, and the valuation basis applied will vary depending on the circumstances of each Private Hydrogen Asset. DCF will be considered where appropriate forecasts are available. The valuation will also consider any recent transactions, where appropriate. For those Private Hydrogen Assets where a trading multiples approach can be taken, the methodology will factor in revenue, earnings or net assets as appropriate for the Private Hydrogen Asset.

Estimated sustainable earnings and cash flows

The selection of sustainable revenue or earnings and cash flows will depend on whether the Private Hydrogen Asset is sustainably profitable or not, and where it is not then sustainable revenues will be used in the valuation. The valuation approach will typically assess Private Hydrogen Assets based on the last twelve months of revenue or earnings, as they are the most recent available and therefore viewed as the most reliable. Where a Private Hydrogen Asset has reliably forecasted earnings previously or there is a change in circumstance at the business which will impact earnings going forward, then forward estimated revenue or earnings may be used instead.

Application of liquidity discount

A liquidity discount may be applied either through the calibration of a valuation against the most recent transaction, or by application of a specific discount.

Credit risk

The Company and Group are exposed to credit risk in respect of trade and other receivables and cash at bank. For risk management reporting purposes, the Company and Group considers and aggregates all elements of credit risk exposure (such as individual obligation default risk, country risk and sector risk).

	31 December 2023	31 December 2022
	£'000	£'000
Trade and other receivables	51	641
Cash and cash equivalents	4,626	18,192
Total	4,677	18,833

The cash and cash equivalents are held with Northern Trust Bank, EFG International Bank, Royal Bank of Scotland and through the Goldman Sachs- Liquid reserve fund. The Fitch Rating credit rating of Northern Trust Bank is AA (2022: AA), EFG international Bank is A (2022: A), Royal Bank of Scotland A+ (2022: A+) and the Goldman Sachs Liquid reserve fund is AAA (2022: AAA).

At the year end there were no trade and receivables past due. The credit risk exposure is minimised by dealing with financial institutions with investment grade credit ratings.

Liquidity risks

Liquidity risk is the risk that the Company or Group may not be able to meet a demand for cash or fund an obligation when due. The Investment Adviser, AIFM and the Board continuously monitor forecast and actual cashflows from operating, financing and investing activities to consider payment of dividends, or further investing activities.

Financial assets and liabilities by maturity at the year end are shown below:

	31 December 2023			31 December 2022

Operational risk

Operational risk is the risk of direct or indirect loss arising from a wide variety of causes associated with the processes, technology and infrastructure supporting the activities relating to financial instruments, either internally or on the part of service providers, and from external factors other than credit, market and liquidity risks such as those arising from legal and regulatory requirements and generally accepted standards of investment management behaviour.

Operational risk is managed so as to balance the limiting of financial losses and reputational damage with achieving the investment objective of generating returns to investors. The AIFM works with the Board to identify the risks facing the Company and the Limited Partnership. The key risks are documented and updated in the Risk Matrix by the AIFM. The primary responsibility for the development and implementation of controls over operational risk rests with the Board.

This responsibility is supported by the development of overall standards for the management of operational risk, which encompasses the controls and processes at the service providers and the establishment of service levels with the service providers. The Directors' assessment of the adequacy of the controls and processes in place at service providers with respect to operational risk is carried out through having discussions with and reviewing reports, including those on their internal controls, from the service providers.
