H(2 )geo-storage has been suggested as a key technology with which large quantities of H(2 )can be stored and withdrawn again rapidly. One option which is currently explored is H(2 )storage in sedimentary geologic for-mations which are geographically widespread and potentially provide large storage space. The mechanism which keeps the buoyant H(2 )in the subsurface is structural trapping where a caprock prevents the H(2 )from rising by capillary forces. It is therefore important to assess how much H(2 )can be stored via structural trapping under given geo-thermal conditions. This structural trapping capacity is thus assessed here, and it is demonstrated that an optimum storage depth for H(2 )exists at a depth of 1100 m, at which a maximum amount of H(2 )can be stored. This work therefore aids in the industrial-scale implementation of a hydrogen economy.
