Ryan Hanrahan, CEO of Wave International commented:

"The award of these two packages is a key milestone as the project moves to progress FEED activities for Train 1 and piloting for Train 2. Through the testwork and detailed evaluations, we have been able to demonstrate that the key process equipment will meet the requirements of the flowsheet and enable production of an ultra-pure lithium hydroxide monohydrate product."

Nipen Shah from Jord Proxa commented:

"JordProxa are pleased to be working with TVL and Wave International. Our process technology for lithium hydroxide crystallisation is perfectly suited to this project, and the testwork to date has demonstrated excellent results. We look forward to progressing towards a final commercial agreement for what looks to be the UK's first large scale Lithium Hydroxide processing facility."

Mathieu Bailly from Eurodia commented:

"Eurodia are pleased to see TVL as a company embracing electrochemistry as a critical technology for next generation lithium hydroxide processing. With our technology well proven in many industries, the independent testwork done by TVL and other work we have completed on lithium processing provides for a low-risk technology solution for the project.

Vikki Jeckell, Director of Alkemy and Tees Valley Lithium commented:

"We are delighted to announce today a significant milestone in our journey. Awarding preferred vendor status to JordProxa and Eurodia is not just a testament to our commitment to excellence, but also a recognition of the innovative strides we are making in the industry.

Our partnerships with these industry leaders reflect our dedication to not only align with the best but also to drive forward the standards of lithium refining.  These collaborations are pivotal in our mission to innovate and deliver sustainable, efficient, and cutting-edge solutions in the field.

On behalf of the board, I extend our gratitude to our team, partners, and stakeholders who have been instrumental in reaching this milestone. We are excited about the future and look forward to continuing our journey towards excellence in lithium refining."

TVL Train 1 - Crystalliser technology package award - JordProxa

Train 1 utilises the standard causticisation process for the production of lithium hydroxide monohydrate. The flowsheet comprises conversion of various feedstocks if required, impurity removal, evaporation, glauber's salt crystallisation, anhydrous sodium sulphate crystallisation and multi-stage lithium hydroxide crystallisation followed by product handling and bagging.

The Class 4 study completed by Wave International as the lead process designer defined the crystallisation circuit parameters. JordProxa have considered these parameters and completed metallurgical testwork, producing high purity Lithium hydroxide Monohydrate.

On this basis, a crystallisation process island has been proposed which includes:

·    PLS evaporation;

·    Glauber's salt crystalliser;

·    Anhydrous sodium sulphate crystalliser; and

·    Multi-stage lithium hydroxide crystallisers.

The process island approach is a key aspect of the overall plant design, simplifying the procurement activities and reducing interface risk. This approach represents an evolution from what has been achieved by the recent Australian plants and incorporates significant learnings from those projects. This next generation of crystalliser design will provide for significant technical de-risking of TVL's project.

Based on the preferred vendor status, TVL Wave International and JordProxa will work together towards a finalised commercial contract including:

·    basic engineering and design (including modularisation);

·    process guarantees;

·    detailed manufacturing schedule including long lead milestones; and

·    further optimisation testwork and supply of pilot scale equipment.

The next phase of works planned is completion of basic engineering design, which is a critical activity to underpin Front End Engineering Design (FEED) for the balance of the plant and infrastructure.

Design for a pilot plant is also underway, which will produce sales and marketing samples to progress product qualification.

TVL Train 2 - Electrochemical cell package award - Eurodia Industrie SAS

Train 2 utilises an electrochemical process to produce lithium hydroxide from lithium sulphate or lithium carbonate. The front half of the flowsheet is similar to the conventional process, with some additional impurity removal stages ahead of the electrochemical cells. The electrochemical cells use electricity (instead of a chemical reagent) to separate lithium sulphate into sulphuric acid and lithium hydroxide, which can then be crystallised into lithium hydroxide monohydrate. A similar, but simplified, crystallisation circuit is used for this final step.

This approach is suited to a facility which has access to abundant, cheap renewable energy and has the ESG benefits of:

·    removing the need for sodium hydroxide as a reagent (which is currently in high demand); and

·    removing anhydrous sodium sulphate as a bi-product

The sulphuric acid bi-product can either be concentrated and used to digest alternative feedstocks (or used in other low-specification applications) or converted to gypsum and used in local industry. It is noted that gypsum is currently imported at the adjacent PD Ports.

The separation of salts via electrochemical cells is a proven technology in water treatment, with a number of large-scale plants operating throughout Europe.

The Class 4 study by Wave International as the lead process designer defined the electrochemical  circuit parameters. Metallurgical testwork was completed in parallel at two specialist laboratories, including a membrane screening program in which Eurodia membranes were compared to others by an independent laboratory. This testwork independently showed the Eurodia technology to have superior lithium recovery and sulphuric acid quality and was a key factor in the technology selection.

Based on the preferred vendor status, TVL Wave International and Eurodia will work together towards a finalised commercial contract including:

·    Basic engineering and design;

·    Process guarantees;

·    Detailed manufacturing schedule including long lead milestones; and

·    Further optimisation testwork and supply of pilot scale cells.

TVL and Wave International are jointly finalising the technology development framework for Train 2, with the next stage being the completion of a pilot scale plant development. The supply of a pilot scale cell and progression of basic engineering design will be the next stages of engagement with Eurodia.
