Abstract. The large-scale storage of hydrogen plays a fundamental role in a potential future hydrogen economy. Although the storage of gaseous hydrogen in salt caverns already is used on a full industrial scale, the approach is not applicable in all regions due to varying geological conditions. Therefore, other storage methods are necessary.
Hydrogen energy storage has the advantages of cross-seasonal, cross-regional, and large-scale storage, as well as quick response capabilities, which is applicable to all links
Research highlights Comparison of battery only off-grid energy system to H 2 hybrid system. Onsite generated H 2 is used as a fuel for cooking and fuel cell for electricity. Battery provides short term storage, hydrogen provides seasonal storage. H 2 hybrid system requires 25% battery capacity of battery only system. H 2 hybrid system is
The nickel-hydrogen battery exhibits an energy density of ∼140 Wh kg −1 in aqueous electrolyte and excellent rechargeability without capacity decay over 1,500 cycles. The estimated cost of the nickel-hydrogen battery reaches as low as ∼$83 per kilowatt-hour, demonstrating attractive potential for practical large-scale energy storage.

Hydrogen increasingly looks likely to have a role to play in achieving decarbonisation targets worldwide, and investments and innovation are scaling up. But costs remain high and for clean hydrogen to be most effective at integrating high shares of renewable energy, storage is a vital piece of the puzzle, writes Georgina Ainscow, a
It can produce pressurised hydrogen by using low cost non-noble metal catalysts. However, the performances are still lower than that of the conventional PEM electrolysis technology. In this study, we
However, many large economies have limited renewable energy generation capacity, which leads to the identification of strategic sites for the global export of hydrogen. The aim of this work is to

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.
