Beschreibung
Zusammenfassung:	The present invention provides a method and system for storing energy in the form of methane. The method comprises at least a step of generating electric energy from a renewable and/or non-renewable energy source, a step of using at least partially the electric energy generated from a renewable and/or non-renewable energy source for the electrolysis of water and/or brine, thereby producing hydrogen and/or oxygen, and a step of using at least partially the hydrogen produced by electrolysis of water and/or brine and carbon dioxide for producing methane by methanogenic micro-organisms in a reaction vessel, this step comprises contacting the methanogenic microorganisms with an in-gas feed comprising at least said hydrogen and carbon dioxide. The invention further provides a system for storing energy in the form of methane comprising at least one device for generating electric energy from a renewable and/or non-renewable energy source, at least one device for producing hydrogen and oxygen by the electrolysis of water and/or brine, and at least one bioreactor comprising a reaction vessel suitable for growing, fermenting and/or culturing methanogenic microorganisms. Also provided is said bioreactor.
