Notes to Editors

Oxford Catalysts enables modular Gas-to-Liquids ("GTL") plants to convert unconventional, remote and problem gas into valuable liquid fuels. Systems based on the Group's technology (marketed under the brand name Velocys) are significantly smaller than those using conventional technology, enabling modular plants that can be deployed cost effectively in remote locations and on smaller fields than is possible with competing systems. Together with world-class partners, Oxford Catalysts provides complete modular GTL solutions that address an untapped market of up to 25 million barrels of fuel a day.

Oxford Catalysts Group PLC is listed on the AIM market of the London Stock Exchange (LSE: OCG). The Group has some 85 employees with facilities near Oxford, UK and Columbus, Ohio, USA.
