Gas and electricity rely on each other to achieve full decarbonisation
TYNDP 2020 scenarios show that power-to-gas is a key technology to integrate electricity from variable renewables to a larger scale. Power-to-gas supports the development of variable renewables, like wind and solar, since it allows to produce hydrogen when the electricity demand is lower than the renewable electricity production. Furthermore, biomethane and hydrogen produced from renewable electricity can be stored in the gas system for longer period and transported efficiently over longer distances, complementing the short term flexibility of battery storage.
Equally, the gas system needs all decarbonisation technologies, including power-to-gas, to further decarbonise the gas supply, which can in return be used to produce decarbonised electricity when the electricity demand is higher than the renewable electricity generation.
