Very large amounts of hydrogen can be stored in constructed underground salt caverns of up to 500,000 cubic meters at 2,900 psi, which would mean about 100 GWh of stored electricity electricity. In this way, longer periods of flaws or of excess wind / PV energy production can be leveled. Even balancing seasonal variations might be possible.

The study presents a comprehensive review on the utilization of hydrogen as an energy carrier, examining its properties, storage methods, associated challenges, and potential future implications. Hydrogen, due to its high energy content and clean combustion, has emerged as a promising alternative to fossil fuels in the quest for
Electricity can be stored in a variety of ways, including in batteries, by compressing air, by making hydrogen using electrolysers, or as heat. Storing hydrogen in solution-mined salt caverns will be the best way to meet the long-term storage need as it has the lowest cost per unit of energy storage capacity. Great Britain has ample geological
A new paradigm is needed for electricity storage in the renewables energy market. Today, what passes for "grid storage" are technologies that provide, at most, eight to 12 hours of discharge. If we are to successfully go to 100% renewables and to wean electricity generation from fossil fuels, we need storage to have up to 592 hours
The potential role of hydrogen in balancing the power grid and the potential development of international trade would require the development of more storage capacity and its flexible operation.
