Prometheus Fuels reaches TRL 9 with Titan Forge Alpha prototype

In California, Prometheus Fuels has reached commercial readiness for its proprietary e-Fuel production system. The company’s Titan Forge Alpha prototype has successfully integrated a full-scale 50-cell Faraday Reactor validating its core technology at TRL 9, the highest benchmark for real-world deployment and system maturity.

With this milestone, Prometheus becomes the only company capable of producing low-cost carbon-neutral e-Fuel using direct air capture (DAC) and intermittent renewable energy, fully off-grid. The company also stands apart from other e-fuel producers in not needing subsidies or hydrogen. Its Titan Forge Alpha plant, the world’s first operational DAC synthetic fuel facility, is already generating e-methanol from air and solar power.

Next up: Titan Fuel Forge One, the company’s first commercial-scale fuel production system. It will use the same proven stack architecture and kick off a new era of production for Prometheus. To date, the company has pre-sold more than 11 million tons of e-Fuel to be delivered over the next decade, reflecting strong demand from global energy buyers and deep market confidence in the company’s technology.

The Faraday Reactor, a hydrocarbon electrolyzer that converts CO2 from an integrated DAC tower directly to fuel, is core to Prometheus’ system. Designed to operate on variable power inputs, the system thrives in remote, off-grid environments where wind and solar energy are abundant, unlocking low-cost, distributed fuel production at a global scale.
