ETFuels Launches FEED for Landmark First-Mover  e-Methanol Project in US

Austin, Texas - 27th October 2025 - ETFuels, a leading global e-fuels developer announced the start of Front-End Engineering Design (FEED) for its flagship Rattlesnake Gap e-methanol project in West Texas - marking a major step toward the commercial-scale production of e-fuels for global shipping and aviation markets. Once completed, the project will be the largest e-methanol plant in the U.S.

Texas: the World’s e-Fuels Epicentre

Located in the energy capital of the world, Rattlesnake Gap exemplifies why Texas offers an unparalleled environment to build e-fuel projects. The state combines phenomenal renewable energy resources, a world-class industrial supply chain and a pro-business culture. These advantages - unmatched anywhere else - enable ETFuels to deliver e-fuels at unprecedented speed and scale.

“Texas is on track to become the world leader in e-fuels production so it made perfect sense for ETFuels to build our first project here,” said Lara Naqushbandi, CEO of ETFuels. “Rattlesnake Gap is one of an elite few e-fuels projects worldwide to have reached this advanced stage of development - and the first to pioneer a fully integrated behind-the-meter model at commercial scale, reinforcing Texas’s position as a true energy innovator.”

World-Class Partners, Proven Track Record

The FEED is being performed by S&B Engineers and Constructors headquartered in Houston. The project is being designed with the most experienced supply-chain partners in the industry. John Cockerill is providing electrolyzer technology from its Baytown, Texas factory. The project will also utilize Johnson Matthey eMERALD technology to create methanol.

Regulation Driving Demand

Rattlesnake Gap directly responds to growing demand for clean fuels, in particular from Europe’s FuelEU Maritime regulation, as well as the introduction of e-SAF mandates under UK and EU law. ETFuels’ production will serve both aviation and shipping markets, establishing Texas as a key transatlantic hub for next-generation e-fuel supply.

A Platform Built for Scale

Since its formation less than three years ago, ETFuels has built a global portfolio spanning the U.S., U.K., Spain, and Finland - together representing over 2.5 GW of renewables and a clear pathway to deliver RFNBO-compliant projects at pace. In a market dominated by concepts and MoUs, ETFuels is building real plants, with real partners, on real timelines.
