Method for compensating load peaks during energy generation and/or for generating electrical energy and/or for generating hydrogen, and a storage power plant

A method of compensating for load peaks during the generating of electrical energy and/or for the generating of electrical energy by utilizing the heat of heated carrier gas for the electricity generation, and/or for the utilization of the heat of the heated carrier gas for hydrogen generation, comprising:

• heating of carrier gas, including hot air, in at least one gas heater, wherein hot carrier gas with a specified target charge temperature exits from the gas heater,
• thermal charging of at least one heat storage module of a plurality of heat storage modules of the storage power station by releasing heat from the hot carrier gas from the gas heater to a heat storage material of the heat storage module,
• time-delayed thermal discharge of at least one heat storage module, wherein colder carrier gas, including cold air, flows through at least one heat storage module and heat from the heat storage material is transferred to the colder carrier gas for the heating of the carrier gas and wherein heated carrier gas with a specified discharge temperature exits from the heat storage module, and
• utilization of the heat transferred to the carrier gas in a process for electricity generation and/or hydrogen generation, wherein a plurality of heat storage modules connected in series form a heat storage series and heated carrier gas flows through them in succession during the charging, wherein the charging of a following heat storage module of the series is done at least partly by direct supply of hot carrier gas from a gas heater.
