Hydrogen storage in salt caverns: Dispelling the myths

December 14, 2021

Hydrogen is widely considered as one of the most influential and promising zero-emission technologies capable of supporting global ambitions in reaching net zero emission targets. With renewable energy demand soaring in recent years, and expected to continue, hydrogen could be a crucial clean energy carrier to compliment renewable energy.

With many of the world’s renewable energy coming from intermittent sources, such as wind and solar, energy storage is becoming more and more of a hot topic to ensure that cost-competitive clean energy is available throughout the year.

Hydrogen is widely regarded as a perfect complement to intermittent energy sources, with hydrogen able to produce green electricity at times where demand is high. This allows renewable energy to be readily available for whenever it is needed. Hydrogen could also be produced during periods in which there is an excess of renewable energy. This could then be stored and used at a later date.

One of the most compelling ways to store vast amounts of hydrogen, and renewable energy, is within salt caverns – unique geographical formations underground that provide a basis to store large amounts of clean energy in a cost-competitive manner.
