Founded in 2021, OXCCU is developing proprietary catalysts and reactor designs that directly hydrogenate CO₂ to create hydrocarbon syncrude branded as OXFUEL, which can be refined into jet-fuel-grade SAF. Its single-step, iron-based Fischer-Tropsch process eliminates the RWGS stage and reduces hydrogen demand, promising lower capital and operating costs than competing e-fuel pathways. The company operates from Begbroke Science Park and London Oxford Airport, where its OX1 demonstration plant was validated in 2024. OXCCU is positioning OXFUEL to help the UK meet its target of 10% SAF in jet fuel by 2030 and is now researching how its fuel can limit non-CO₂ warming effects such as soot-induced contrail formation. Financially, the start-up secured €20.6 million of initial funding in June 2023, followed by a €23.7 million round in September 2025, and most recently obtained a €2 million grant from the ATI Non-CO₂ Programme. These funds support technology scale-up, commercial deployment and climate-impact validation, underscoring OXCCU’s emergence as a leading UK climate-tech innovator.
