Climate tech startup Sora Fuel secured $14.6 million in Series A funding to accelerate the development of its technology for producing sustainable aviation fuel (SAF) using water, air, and renewable energy as inputs. The Boston-based company, founded in 2024, has developed a proprietary process that captures CO₂ directly from ambient air and converts it into syngas in a single integrated step, co-producing hydrogen while eliminating the energy-intensive sorbent regeneration step that accounts for over 90% of costs in conventional direct air capture (DAC) systems. Sora Fuel claims its platform can capture carbon at less than $50 per ton—approximately one-tenth the cost of traditional DAC approaches—and aims to produce SAF at costs below $5 per gallon, making it price-competitive with fossil fuels. The new capital will fund the construction and operation of a pilot production facility designed to scale daily unit production from gallons to barrels, with a demonstration milestone expected within 18 to 24 months. The funding round was co-led by Spero Ventures and Inspired Capital, with additional investments from Engine Ventures and Wireframe Ventures, and includes Marc Tarpenning, co-founder of Tesla, as a board member and venture partner at Spero Ventures.
