OxCCU wins sustainability award for transformative single-step SAF process

UK startup OXCCU, which says it has developed a single-step process to convert waste carbon into sustainable aviation fuel (SAF), has been named winner of the 2026 Startups 100 Sustainability Award, a recognition for firms demonstrating innovative and impactful sustainability practices. According to Hydrocarbon Engineering, the accolade follows a year of technical milestones and fresh investment for the Oxford University spin‑out.

OXCCU claims its patented iron catalyst combines captured CO2 with green hydrogen to produce jet‑fuel‑range hydrocarbons directly, avoiding intermediate steps and reducing byproducts. The company says this single‑reaction approach lowers both capital and operating costs, potentially cutting the price of SAF versus more complex routes. Industry observers note that simplifying process chemistry can materially affect project economics and scale‑up risk, particularly for electrofuel pathways that remain capital‑intensive.

At its OX1 demonstration facility at London Oxford Airport, OXCCU reports it has logged 1,000 hours of continuous liquid‑fuel production with “high conversion rates and excellent selectivity for SAF,” according to the Hydrocarbon Engineering write‑up. The business has set a commercial target of producing 10,000 tonnes per year of SAF before 2030; for context, a single Boeing 787 transatlantic flight consumes roughly 50 tonnes of jet fuel.

The company completed a £20.75 million ($28 million) Series B funding round in late 2025, described in a PR Newswire release as oversubscribed and joined by strategic new backers including Orlen VC, Safran Corporate Ventures, International Airlines Group (IAG), Hostplus and TCVC, alongside existing investors such as Clean Energy Ventures, IP Group/Kiko Ventures, Aramco Ventures, Eni Next, Braavos Capital and the University of Oxford. The PR Newswire statement said the capital will accelerate commercialisation and fund the next phase of technology scale‑up; other regional reporting confirms OXCCU is building a second demonstration plant, OX2, which the company expects to be fully operational in 2026.

OXCCU has also secured public support: the company is among 17 firms awarded a share of £63 million from the UK government’s Advanced Fuels Fund, a programme the company says will underwrite detailed design and construction work for OX2 and help move toward lower‑cost, lower‑carbon aviation fuel production. The Advanced Fuels Fund is billed by government sources as supporting around 1,400 jobs and aimed at positioning the UK as a leader in SAF.

Recognition of OXCCU’s technology extends beyond grants and private capital. The firm was named to the 2025 Global Cleantech 100, a list that highlights promising private clean‑technology companies, a company press release said, and the Startups 100 award underscores investor and sector interest in electrofuel and carbon‑utilisation approaches.

While OXCCU presents a compelling pathway, experts in industrial decarbonisation caution that several hurdles remain before such processes deliver SAF at scale. Commercial viability will depend on sustained access to low‑cost, low‑carbon hydrogen and captured CO2, continuous catalyst performance at multi‑megatonne scales, and favourable policy frameworks including SAF mandates, low‑carbon fuel credits and capital subsidy mechanisms. Supply chain integration and long‑lead equipment for modular or skid‑mounted plants also influence time to market and unit economics.

OXCCU’s CEO and co‑founder Andrew Symes said: “Being recognised in the Startups 100 Index reflects the momentum we have built this year. Securing our Series B funding, starting the build of our second demonstration plant OX2, and growing the team has given us strong foundations to move forward. With strong investors alongside us, the focus now is on proving the technology at a larger scale and building the foundations for a pathway that can make a meaningful difference to future aviation fuel production.” The company frames the immediate priority as validating scale‑up performance and cost curves that would make SAF competitive with conventional jet fuel and other sustainable pathways.

For industrial decarbonisation stakeholders, OXCCU’s progress highlights the evolving mix of private capital, strategic aviation and industrial partnerships, and targeted public funding that many analysts see as necessary to commercialise alternative jet‑fuel technologies. Whether OXCCU’s single‑step iron‑catalyst route can deliver the predicted reductions in capital intensity and operating cost will be a critical datapoint as policymakers and investors allocate resources across SAF options, from HEFA and lipids‑based routes to power‑to‑liquid electrofuels and synthetic paraffinic kerosene.

As the company moves from demonstration to commercial pilot, the sector will be watching for independently verified performance data from OX2, the longevity and regenerability of the iron catalyst under real‑world feedstocks, and the firm’s ability to secure long‑term offtake and hydrogen and CO2 feedstock contracts that underpin project finance. According to reporting across company releases and trade coverage, OXCCU intends to explore applications for its hydrocarbons beyond aviation in chemicals and plastics, signalling potential diversification of revenue streams should aviation uptake progress more slowly than anticipated.
