The Mountaineer GigaSystem™ is a lifecycle carbon neutral clean hydrogen facility and microgrid designed to produce over 500 metric tons per day (“MTPD”), per train in Mason County, West Virginia utilizing Fidelis’ proprietary FidelisH2® technologies combined with carbon capture utilization and sequestration (“CCUS”) for carbon neutral hyperscale datacenters, greenhouses, transportation, and steel production.
Mountaineer is a Project Partner in the Appalachian Regional Clean Hydrogen Hub or “ARCH2,” a regional clean hydrogen hub formed to support the “commercial lift-off” of a full value Hydrogen Hub across communities in the Northern Appalachian region.
