What OXCCU Is & Why It Matters
OXCCU is a UK-based climate tech startup and Oxford University spin-out developing breakthrough technology to turn waste carbon dioxide (CO₂) and green hydrogen into sustainable aviation fuel (SAF) and other liquid hydrocarbons. Its approach aims to decarbonise the aviation industry, one of the hardest sectors to clean up due to heavy fossil-fuel reliance. (oxccu.com)
Technology Highlights
- Single-step conversion: OXCCU’s patented iron-based catalyst allows CO₂ and hydrogen to be directly converted into jet-fuel-range hydrocarbons in a single catalytic reaction — avoiding more complex multi-stage processes used elsewhere. (Biofuels International)
- Lower costs & emissions: This simplification reduces capital and operating costs and significantly lowers overall carbon intensity compared with conventional methods. (Startups.co.uk)
- Feedstock flexibility: The process can handle different carbon sources (e.g., recycled CO₂, gasified biomass), enhancing commercial viability. (oxccu.com)
OXCCU represents a practical example of turning waste carbon into valuable, low-carbon products, a central theme in climate solutions. (oxccu.com)

Regulations such as the UK’s SAF mandate and the EU’s ReFuelEU framework are helping stimulate demand, but production infrastructure must still catch up. (oxccu.com)
Summary
OXCCU has emerged as a standout climate tech innovator in the UK and globally, winning the 2026 Startups 100 Sustainability Award for its work turning waste carbon into sustainable aviation fuel using a novel single-step catalytic process. The company has attracted major funding, prestigious industry partnerships, and public research grants, highlighting its potential to contribute significantly to greenhouse-gas reduction in aviation — one of the hardest-to-decarbonise sectors. (Biofuels International)
Here are detailed case studies and expert/user comments showing how OXCCU is gaining sustainability recognition for its carbon-to-fuel innovation — particularly via the 2026 Startups 100 Sustainability Award and other real-world milestones.
Case Study 1 — Startups 100 Sustainability Award & OX1 Demonstration Success
What happened:
In January 2026, OXCCU was named the winner of the Startups 100 Sustainability Award, a top UK recognition for early-stage companies making exceptional contributions to environmental sustainability. The award celebrates both innovation and impact in tackling climate change. (Biofuels International)
Why it matters:
- OXCCU’s technology directly converts CO₂ and green hydrogen into jet-fuel-range hydrocarbons in one catalytic step, which is simpler, cheaper and lower-emission than conventional multi-stage SAF production. (Biofuels International)
- The process uses a patented iron-based catalyst that avoids intermediate stages and reduces both capital and operational costs, improving commercial viability. (Biofuels International)
- The award highlighted lifecycle emission reductions of up to ~90% versus fossil fuels, a crucial metric for sustainability impact. (Startups.co.uk)
Demonstration plant evidence:
OXCCU’s OX1 demonstration facility at London Oxford Airport reached over 1,000 operating hours, producing high-conversion liquid fuel with strong selectivity toward SAF. This operational proof was central to the sustainability award decision. (Biofuels International)
Funding momentum:
Following this progress, OXCCU closed a £20.75m Series B funding round in late 2025 to accelerate its scale-up and build a second demonstration plant (OX2). (Biofuels International)
Case Study 2 — First-of-a-Kind OX1 Plant Launch & Scale-Up Path
Technical breakthrough:
Unlike conventional SAF pathways that require multiple energy-intensive steps, OXCCU’s innovation lies in a single direct conversion of CO₂ + H₂ to hydrocarbons using its proprietary catalyst. This one-step Fischer-Tropsch (F-T) variant simplifies the process, reducing complexity and cost. (oxccu.com)
Plant deployment:
The OX1 plant at Oxford Airport — the first of its kind — started operations in September 2024 producing SAF precursors under real conditions. It served as the key bridge from lab research to real industrial output. (oxccu.com)
Scaling strategy:
- OX1 demonstrated technical feasibility with continuous fuel production. (oxccu.com)
- A larger facility, OX2, is planned to be operational in 2026 with a much higher output capacity, strengthening commercial scalability. (oxccu.com)
- Long-term goals include producing ~10,000 tonnes of SAF per year by 2030, materially contributing to aviation decarbonisation targets. (Startups.co.uk)
Case Study 3 — Grants & Policy Support Boosting Innovation
Advanced Fuels & ATI Grants:
OXCCU has secured government support to complement private investment:
- It received funding under the UK Advanced Fuels Fund to help design and build the next OX2 facility. (oxccu.com)
- Crucially, OXCCU became the first SAF company to win an £1.8m ATI Non-CO₂ Programme grant, aimed at investigating how its SAF product’s non-CO₂ climate impacts (like soot and high-altitude cloud effects) might be further reduced. (oxccu.com)
Why this matters:
While CO₂ emissions are the primary focus, non-CO₂ effects (e.g., particulate emissions affecting cloud formation) significantly influence aviation’s climate impact. Research funded by the grant strengthens OXCCU’s leadership in producing cleaner fuels with a broader climate benefit. (oxccu.com)
