Mountaineer C2H

The Mountaineer coal-to-hydrogen facility is part of Fidelis New Energy’s Mountaineer GigaSystem in Mason County, West Virginia. In partnership with Babcock & Wilcox (B&W), the project will deploy BrightLoop™ chemical-looping technology to convert coal, biomass, or natural gas into low-carbon hydrogen while producing a pure, sequestration-ready CO₂ stream. The captured CO₂ will be permanently stored in nearby deep geologic formations under multiple EPA Class VI permits. The first phase is planned to process ~200 metric tons of coal per day into hydrogen, scaling over four phases to more than 2,900 t/day of hydrogen production. When fully built out, the site aims to capture and store up to ~10 million metric tons of CO₂ annually, supplying hydrogen for power generation, industrial use, and the co-located Monarch AI data center campus, with initial operations targeted for 2028.
