Patent ID: 11174785

Abstract:
The invention relates to a method for storing energy and for dispensing energy into an energy supply grid by means of a pressurized gas storage power plant, which has at least one first storage chamber and at least one second storage chamber separate from the first, wherein in order to store energy pressurized gas is taken from the lower-pressure storage chamber, is compressed by means of a compression machine and the compressed pressurized gas exiting the compression machine is routed into the other storage chamber; in order to dispense energy pressurized gas is taken from the higher-pressure storage chamber, is routed through an expansion machine and the expanded pressurized gas exiting the expansion machine is transferred into the other storage chamber, wherein the expansion machine dispenses energy to the energy supply grid, wherein the pressurized gas is heated by means of a heating device prior to or upon supply to the expansion machine. The invention also relates to a corresponding pressurized gas storage power plant and to a computer program for carrying out the method.
