Sora Fuel, a climate technology company producing jet fuel from air, water, and renewable energy, announced a $14.6 million funding round co-led by Spero Ventures and Inspired Capital. Additional participation came from Engine Ventures and Wireframe Ventures. Funding will support construction of a pilot facility aimed at scaling production of sustainable aviation fuel.
Breakthrough Air-to-Fuel Technology
Sora Fuel developed a proprietary system capturing CO₂ directly from ambient air and converting it into syngas in a single integrated step. The process co-produces hydrogen while bypassing energy-intensive regeneration used in conventional direct air capture, significantly lowering production costs and enabling an economically viable pathway to sustainable aviation fuel.
The pilot facility will scale production from gallons to barrels per day, with demonstration targeted within 18 to 24 months.
“Sora Fuel has built something the clean fuels industry has been searching for: a technology that can actually reach unsubsidized cost parity with fossil fuels,” said Marc Tarpenning, Venture Partner at Spero Ventures, Sora Fuel board member, and co-founder of Tesla. “The team has demonstrated exceptional scientific rigor and engineering execution. Their approach to direct air capture and fuel synthesis is, to our knowledge, the first that makes an economically viable air-to-fuels pathway genuinely credible. We’re proud to lead this round.”
Addressing Aviation Emissions
Aviation contributes roughly three percent of global emissions, while demand for air travel continues to grow. Sustainable aviation fuel remains limited by high production costs tied to carbon feedstocks, green hydrogen, and clean power.
Path to Commercial Deployment
Sora Fuel targets captured carbon costs below $50 per ton and a pathway to sustainable aviation fuel priced under $5 per gallon. The company reports partnership and offtake interest from airlines, energy companies, and aviation manufacturers, supported by regulatory demand in the U.S. and Europe.
“We’ve gone further, faster, and with less capital than anyone in the e-fuels space,” said Gareth Ross, CEO and co-founder of Sora Fuel. “With this funding, we accelerate our path to production-scale manufacturing of our fuel, bringing the aviation industry one enormous step closer to truly affordable, carbon-negative fuel.”
