Various embodiments include a method for determining the thermal consumption of an energy system having a thermal energy storage unit, wherein the energy system generates a total thermal energy within a time range comprising: determining a thermal charging energy of the thermal energy storage unit within the time range; determining a thermal discharging energy of the thermal energy storage unit within the time range; and calculating a resulting thermal consumption within the time range using a sum of the total thermal energy and the difference between the ascertained thermal discharging energy and the ascertained thermal charging energy.

The present disclosure relates to combined heat and power plants. The teachings thereof may be embodied in methods for operating such a plant to provide electrical and thermal energy to a consumer unit, comprising: simultaneously generating electrical energy and heat in a process flow based on a demand for electricity; storing heat generated in excess of a demand for heat; and increasing a heat output when a difference between an actual provided heat output and the demand for heat is exceeded.

Combined heat and power plant and method for operation thereof

A method for operating and electrolytic system may include an electrolyzer for generating hydrogen and oxygen as product gas. Hydrogen and oxygen produced during the electrolytic process are discharged from the electrolyzer. As a result, the efficiency of the electrolytic system is improved, at least one of the product gases in the expansion turbine is expanded, and a generator is driven by the expansion turbine.

The present disclosure relates to thermochemical heat storage units. The teachings thereof may be embodied in systems and methods for operating, including charging and discharging, a thermochemical heat storage unit. For example, a method for operating a thermochemical heat storage unit may include: producing a first steam and feeding it to a heat exchanger; partially condensing the steam with release of its thermal energy, in the heat exchanger; subsequently pressurizing water condensed from the steam; feeding the pressurized water to the heat exchanger; evaporating the water into a second steam; and storing at least a portion of the second steam in a steam storage unit.

The invention relates to a method for operating a high-pressure electrolysis system (), wherein a hydrogen stream () and an oxygen stream () are produced in a high-pressure electrolyzer (), and these are passed out of the high-pressure electrolyzer () under high pressure. In order to increase the efficiency of the high-pressure electrolysis system () with respect to cooling of the hydrogen produced in the high-pressure electrolysis system (), the oxygen stream () is passed into a vortex tube () for decompression, in which the pressure energy of the oxygen is converted to refrigeration. This produces a cold oxygen stream () which is used to cool the hydrogen stream ().
