Prometheus Fuels, a California-based energy technology firm backed by A.P. Moller-Maersk, this week claimed to be the first to produce synthetic fuels using direct air capture (DAC) and off-grid renewable power at commercial scale.
The company’s Titan Forge Alpha prototype, which integrates a 50-cell Faraday Reactor, has been validated at Technology Readiness Level 9 (TRL 9), the highest classification for operational maturity and market deployment. This milestone confirms the system’s capability to synthesise e-methanol from atmospheric carbon dioxide using solar energy without reliance on external grid infrastructure.
At the core of the process is the Faraday Reactor, a hydrocarbon electrolyser designed to convert COâ‚‚ captured from the atmosphere into liquid fuels. The reactor operates efficiently under variable power inputs and is suited to deployment in remote locations with abundant solar or wind energy. Prometheus’ system differentiates itself by operating independently of hydrogen feedstocks, grid electricity, biogenic COâ‚‚ sources, or government subsidies.
Rob McGinnis, founder and CEO of Prometheus, said in a statement: ‘We knew we had to be able to beat fossil fuels on cost from the beginning and that’s what we’ve achieved. We don’t need subsidies, we don’t need hydrogen, we don’t need biogenic point-source CO2, and we don’t need the grid. We can turn the lowest cost energy in the world from solar in the best locations into liquid fuels that can meet the fast-growing need for new power. We’re ready to scale to meet real demand.’
The company is preparing to scale its operations up through the launch of its first commercial-scale facility, Titan Fuel Forge One, which will employ the same reactor architecture. Prometheus reports that it has pre-sold more than 11 million tonnes of e-fuel for delivery over the next decade, signalling strong demand from industrial buyers and growing market confidence in its proprietary technology.
Founded in 2019, Prometheus has attracted investment from several high-profile backers, including BMW, Y Combinator, and Maersk. The Danish shipping giant invested in the company in 2021 as part of its broader strategy to decarbonise its fleet and supply chains.
Prometheus asserts that its synthetic fuel can function as firm, dispatchable baseload energy. The fuel can be stored indefinitely and transported globally without the need for additional transmission infrastructure. This positions the technology as a potential enabler of clean energy access in under-connected regions and off-grid industrial applications.
While synthetic fuels have historically faced economic and technical barriers to scale, Prometheus argues that its integrated DAC and fuel synthesis technology overcomes these limitations. By directly utilising low-cost renewable electricity and atmospheric COâ‚‚, the company aims to offer a scalable and cost-competitive alternative to fossil fuels for sectors such as shipping, aviation, heavy industry, and data centre operations.
