Notes to Editors

Velocys (formerly Oxford Catalysts) enables modular gas-to-liquids (GTL) plants to convert unconventional, remote and problem gas into valuable liquid fuels. Systems based on the Company's technology 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, Velocys provides complete modular GTL solutions that address an untapped market of up to 25 million barrels of fuel a day.

Velocys plc is listed on the AIM market of the London Stock Exchange (LSE: VLS). The Company has approx. 100 employees with facilities in Houston, Texas, USA and near Oxford, UK and Columbus, Ohio, USA.
