Company Description
Prometheus Fuels is an energy technology company that develops carbon-neutral synthetic fuels by converting atmospheric carbon dioxide and water into hydrocarbon fuels, including gasoline, diesel, and jet fuel, using renewable electricity. The company's process utilizes a proprietary 'no-desorb' Direct Air Capture (DAC) technology and a Faraday Reactor system. Founded in 2019 by Rob McGinnis and Beth Smith, the Santa Cruz-based startup is backed by investors such as Maersk Growth, BMW i Ventures, and Y Combinator.
The company has announced a series of technological and commercial milestones. These include a new process to create Sustainable Aviation Fuel (SAF) at less than $2.50 per gallon and a DAC method that reportedly costs less than $50 per ton of CO2. Prometheus has also launched "AI fuel," a product designed to provide off-grid, carbon-neutral power for data centers, and is now taking orders. Real-world deployments include the construction of a 200-ton-per-year DAC system and a demonstration vehicle, the 'Promethean Stang,' which runs on fuel made directly from air. With the completion of its 50-cell Faraday Reactor, the company is preparing for commercial rollout.
