We use solar and wind power to make zero net carbon electrofuels
We remove CO2 and water from the air and use electricity from solar and wind power to turn them into zero net carbon electrofuels. These are gasoline, diesel, and jet fuels that work in existing cars, trucks and planes without requiring modification of their engines, and don't contribute to global warming because they don't add any new CO2 to the atmosphere. Each gallon of our electrofuels means a gallon of fossil oil left in the ground forever. Importantly, these fuels for the first time can compete with fossil fuels on price - our zero net carbon jet fuel has a price of one cent per gallon less than fossil jet fuel. American Airlines ordered 10 million gallons of this fuel and we will start shipping it next year.
Prometheus Fuels produces carbon-neutral liquid fuels by converting electricity (via direct air capture and electrochemistry) into fuels like kerosene, diesel, and methanol. Their approach enables storage of renewable energy as liquid fuels for aviation, shipping, and data centers, aiming to compete with fossil fuel prices.
Prometheus stores electricity as liquid fuels (diesel, jet fuel, methanol) through direct air capture and a 100% electrochemical process. The system can operate on grid or off-grid solar and wind to produce carbon-neutral fuels, including on-site or portable setups for remote locations. Their Ultra Long Duration Energy Storage (ULDES) facilities store renewable energy seasonally by producing liquid fuels for months at a time and using them to provide firm, dispatchable power when needed.
Who it’s for: Industries needing carbon-neutral liquid fuels and long-duration energy storage, including aviation, shipping, data centers, and remote or grid-stressed energy consumers.

Rob McGinnis is Founder and CEO of Prometheus, the first unicorn in e-fuels. Prometheus removes CO2 from the air and uses solar and wind power to turn it into zero net carbon petrol, diesel, jet, and RNG fuels that are superior to fossil fuels at a lower price. Rob has launched three venture backed startups in the fields of desalination, nanotechnology, and energy, and has over 20 patents in these fields. He completed his PhD in Environmental Engineering at Yale and is a veteran of US Navy EOD.
