Cushion Gas in Hydrogen Storage—A Costly CAPEX or a Valuable Resource for Energy
The geological storage of hydrogen is a seasonal energy storage solution, and the storage capacity of saline aquifers is most appropriately defined by quantifying the amount of hydrogen that can be injected and reproduced over a relevant time period.
