摘要： The invention relates to a method for storing energy by converting the energy into thermal energy and then generating power by means of a gas turbine set with a compressor (1), an expander (6) and a power generator (8), comprising at least one (3) and a second (4) low-temperature storage unit, where the electric energy is stored only in form of high-temperature heat (above the turbine outlet temperature TOT) in a thermal storage unit (5). Depending on the requirements, a compressed gas from the compressor (1) is heated to a temperature approximating the turbine outlet temperature TOT in a low-temperature storage unit (3, 4) and then heated to a temperature level of at least turbine inlet temperature TIT in a high-temperature storage unit (5) using stored heat from electric energy and supplied to a gas turbine (6) in order to generate power.

摘要： The present invention relates to a process of storing energy through the conversion of thermal energy and subsequent power generation by means of a gas turbine set with compressor (1), expander (6) and power generator (8), with at least one (3) and with a second (4) low-temperature reservoir, and a high-temperature reservoir (5) with bulk material as the heat storage medium (11), characterized in that, the electric energy is stored in the form of high-temperature heat above the turbine outlet temperature TOT in a thermal reservoir (5), that during the power generation phase a compressed gas from the compressor (1) is heated in a low-temperature reservoir (3, 4) to a temperature near the turbine outlet temperature TOT and subsequently heated in a high-temperature reservoir (5) with stored heat from electric power to a temperature level of at least the turbine inlet temperature TIT, and that the ratio between the bed height in flow direction and the mean particle diameter of the bulk material (11) in the high-temperature reservoir (5) is at least 10, preferably at least 100, more preferably at least 250, even more preferably at least 500 and especially preferably at least 1000, in addition, a means in which this process can be used.
