Hy Stor Aims to Use Salt Domes to Store Hydrogen

Hy Stor Energy has applied for federal funding from the US Department of Energy to support its Mississippi Clean Hydrogen Hub project. The company plans to utilise subterranean salt domes in southern Mississippi to store renewable energy-produced hydrogen, taking advantage of the state's geology and shipping corridors. With potential federal investment of up to US$1bn, the project aims to establish Mississippi as a major producer of clean hydrogen, creating a fully integrated ecosystem for renewable energy production, storage, and delivery. Researchers from The University of Texas at Austin’s Bureau of Economic Geology are building a database of salt domes and caverns along the Gulf Coast that are suitable for hydrogen storage, which should also be suitable for helium storage.
