the Power-to-Gas (P2G) approach can facilitate a transition from natural gas to a ‘green’ mixed gas by making use of both of the existing energy grids on a global scale

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. One of the most promising energy storage systems to storage renewables into the existing EU gas infrastructure.

The hydrogen produced is injected into the natural gas system to displace natural gas, so reducing greenhouse gas emissions and reliance upon fuel imports.

If the power is derived mainly from renewable power sources, only low-carbon hydrogen will be produced. Thereby the Power-to-Gas (P2G) approach can facilitate a transition from natural gas to a ‘green’ mixed gas by making use of both of the existing energy grids on a global scale.
