Wind generation curtailments can occur in power systems as wind penetration increases. An
alternative to curtailments is Power to Gas (P2G). The fundamental idea of P2G is to use the surplus energy, that cannot be incorporated to the power system, to produce hydrogen (H2) using an electrolysis process. The hydrogen is reacted with CO2 to produce methane (CH4) that can be injected to the natural gas pipeline network. Hence, natural gas is used an energy store system. This paper presents the results of a study of the development perspectives of P2G in Spain.
