Optimum geological storage depths for structural H2 geo-storage

H 2 geo-storage has been suggested as a key technology with which large quantities of can be stored and withdrawn again rapidly. One option is currently explored storage in sedimentary geologic formations are geographically widespread potentially provide space. The mechanism keeps the buoyant subsurface structural trapping where caprock prevents from rising by capillary forces. It therefore important to assess how much via under given geo-thermal conditions. This capacity thus assessed here, it demonstrated that an optimum depth for exists at 1100 m, maximum amount stored. work aids industrial-scale implementation hydrogen economy. • An exists. A threshold below cannot permanently immobilized caprock. Functions physico-chemical parameters versus discussed.
