Notes to Editors

Oxford Catalysts Group PLC, the leading catalyst innovator for clean fuels,
designs and develops specialty catalysts for the generation of clean fuels from
both conventional fossil fuels and certain renewable sources such as biomass.
Its patent-pending technology is the result of almost 20 years of research at
the University of Oxford's prestigious Wolfson Catalysis Centre, headed by
Professor Malcolm Green, one of the world's most respected inorganic chemists.
Oxford Catalysts was founded by Professor Green and Dr Xiao in October 2004 and
was admitted to trading on the AIM market of the London Stock Exchange on 26th
April 2006, having raised £15m before expenses from a solid base of
institutional investors.

Oxford Catalysts' strategy is to license its catalysts for commercial
application by entering into co-development partnerships with leading
manufacturers, producers and suppliers in the petroleum, petrochemicals, fuel
cells, biogas, steam applications and catalysis markets.

Oxford Catalysts has two key platform technologies. The first is for a novel
class of catalysts made from metal carbides which, for certain reactions, can
match or exceed the benefits of traditional precious metal catalysts at a lower
cost. Applications of these metal-carbide catalysts include the removal of
sulphur from crude oil fractions (known as hydro-desulphurisation or HDS), the
conversion of natural gas or coal into virtually sulphur-free liquid fuels via
the Fischer-Tropsch reaction (known as the GTL and CTL processes respectively),
and the transformation of biogas (waste methane) into syngas - the building
block of liquid fuels.

The second platform relates to chemical reactions involving a liquid fuel
containing an alcohol (such as methanol), hydrogen peroxide and water. The
company's novel catalyst can be used to release hydrogen gas from this liquid
fuel, instantaneously starting from room temperature. This groundbreaking
hydrogen-on-demand technology has the potential to significantly accelerate the
commercial adoption of fuel cells in the portable and other mobile markets, by
providing the much needed source of cheap, safe transportable hydrogen.

Another of the company's catalysts can be used to produce superheated steam
(800c+) from the above fuel, instantaneously starting from room temperature.
Such portable high-temperature steam could have important applications in a
broad range of markets, from cleaning and disinfecting, to motive power and
electricity generation.
