Abstract (en)
[origin: WO2013152748A1] The inevitable surpluses of wind and solar power and the supply shortages that alternate with these surpluses, together with the inadequate suitability of electrical energy for storage, are the greatest obstacles to overcome for the introduction of renewable energy sources. The present application describes a method for generating and storing electrical energy in which synthesis gas is burned in a power plant to generate electrical energy in a power supplying phase and synthesis gas is converted with additional hydrogen into methane in a storage phase and the methane produced is introduced into the natural gas network and stored in the natural gas network, wherein the hydrogen additionally required for forming methane from synthesis gas is obtained by electrolysis of water. The synthesis gas is preferably produced by gasifying coal or coke. The method described uses coal and surplus wind and solar energy to make methane that has little impact on climate change. This methane is a hybrid methane, in which the carbon may be of fossil origin and the hydrogen originates from wind and solar energy. The overall effect is that electrical energy is drawn from the power network, and the methane produced from it with the addition of coal, which has the properties of natural gas, is fed into the gas network. The methane or equivalent thereof of natural gas that is fed in during the storage phase can be drawn again from the natural gas network in the power supplying phase and converted back into electrical energy in a gas power plant.
