Power-to-Gas is an instrument allowing for optimisation of the overall energy system since it deals with excess of renewable electricity (compared to the demand) which is difficult to store in large quantities for a long time.

Power-to-Gas means a conversion of electrical power into a gaseous energy carrier. In a first step, electricity from renewable energy sources is used in an electrolyser to split water into hydrogen and oxygen. This process is called Electrolysis. An additional Methanation step, can be used to synthesise the hydrogen with carbon dioxide into methane.
