Geochemical responses of mineral powder materials and natural rock cores to H2-water exposure in underground hydrogen storage

Geochemical interactions among H 2 , water, and subsurface minerals may affect the integrity of underground hydrogen storage (UHS). Five mineral-enriched powders and one cement material were exposed to H 2 gas, He-water, and H 2 -water for 30 days at 120 °C and 10 MPa. Sandstone,...
