OXCCU, a UK-based start-up, has introduced a groundbreaking hydrogen-based sustainable aviation fuel (SAF) production process that aims to revolutionize the industry. The company's CO2 Fischer-Tropsch (CO2 F-T) technology, utilizing an iron-based F-T catalyst, converts CO2 and green hydrogen into jet fuel in a single step, significantly reducing stages and hydrogen requirements. This innovative approach not only streamlines production but also leads to considerable cost savings - 50% lower capital costs compared to conventional methods and 25% reduced production costs per tonne compared to other techniques like Reverse Water Gas Shift Fischer-Tropsch (RWGA+FT). OXCCU's focus on sustainability is evident as they aim to meet the UK's renewable fuels emission reduction standards and offer the lowest greenhouse gas emissions among similar processes. The company's efforts have been validated at the OX1 demonstration plant in London Oxford Airport, with plans to further develop and commercialize the technology in the coming years. OXCCU's partnership with px Group for a SAF production plant in Hull signals a commitment to scalable and cost-effective solutions for sustainable aviation fuel, highlighting a positive shift towards greener fuel alternatives in the aviation industry.
