Abstract
A method is provided for carbon-dioxide-neutral compensation for current level fluctuations in an electrical power supply system as a result of peaks and troughs in the generation of electrical energy. When a generation peak occurs, electrical energy produced from a regenerative energy source is used in an electrolysis unit for hydrogen generation. A hydrogen flow generated in the electrolysis unit is supplied to a reactor unit that catalytically generates an energy-carrier flow containing hydrocarbon. In a generation trough, the produced energy-carrier flow is burned in a combustion chamber. The thermal energy of the flue-gas flow formed by the combustion is used to generate electrical energy in a turbine process. The generated electrical energy is fed into the electrical power supply system. The flue-gas flow is supplied to the reactor unit as a carbon source for generation of the energy-carrier flow.
