Power to Gas Energy Storage Power-to-Gas energy storage captures excess renewable power using rapid response electrolysis and produces renewable hydrogen which is stored in the gas grid.
Power-to-Gas is the process of converting surplus renewable energy into hydrogen gas by rapid response electrolysis and its subsequent injection into the gas distribution network. Power-to-Gas allows for the storage of significant amounts of energy and the provision of CO2 neutral fuels in the form of the resulting renewable energy gas mix of hydrogen and methane.
