 Abstract: Underground methane (CH4) gas storage offers capacity and state of the art technology to temporarily store and reuse wind and solar energy. Carbon dioxide (CO2) for ethanation can be readily provided in the same way and used in a closed cycle with CO2 separation at the power plant. With enhanced gas recovery employed, CH4 and CO2 could be placed in the same reservoir to be mutually working and cushion gas for each other. Selected gas storage sites of Germany show that they already have the potential to take up 20-60% of the 90-270 TWh excess energy estimated for 2050.
