Rattlesnake Gap

Project Rattlesnake Gap is a commercial-scale e-methanol facility under development by ETFuels in West Texas, designed to produce renewable synthetic fuel for aviation and maritime markets. The project combines approximately 500 MW of behind-the-meter renewable power from wind and solar generation with battery storage to produce green hydrogen via electrolysis, which is then combined with captured CO₂ to synthesize e-methanol. Planned output is about 120,000 tonnes per year, avoiding an estimated 240,000 tonnes of CO₂ emissions annually. The project has entered Front End Engineering Design (FEED). S&B Engineers and Constructors (FEED engineering partner) – responsible for front-end engineering design and early technical execution planning. John Cockerill (Electrolyzer technology supplier) – providing hydrogen electrolysis systems manufactured in Baytown, Texas to produce renewable hydrogen. Johnson Matthey (Process technology provider) – supplying eMERALD methanol synthesis technology for converting hydrogen and CO₂ into e-methanol.
