WHY SHOULD GAS STORAGE FACILITIES BE REGULATED

Gas power generation and energy storage

A promising option is to use excess renewable power to produce hydrogen or “synthetic natural gas” which can be stored for later usage. Power-to-gas needs much of the same infrastructure as gas-to-power, thus limiting risks of climate stranded assets.
