Abstract (en)

[origin: WO2016169928A1] The energy storage device (1) for storing energy comprises: – a high-temperature regenerator (120) containing a storage material and a working gas (A) as heat transfer medium for the purpose of exchanging heat between the storage material and the traversing working gas (A), – a closed charging circuit (100) for the working gas (A), comprising a first compressor (110), a first expander (140), a first recuperator (130) having a first and a second heat exchange duct (130a, 130b), the high-temperature regenerator (120) and a pre-heater (151), wherein the first compressor (110) is coupled to the first expander (140) by means of a shaft (114), – a discharging circuit (200) for the working gas (A), and comprising – a switching means (400, 401) that selectively connects the high-temperature regenerator (120) to either the charging circuit (100) or the discharging circuit (200), such that the circuit containing the high-temperature regenerator (120) forms a closed circuit.
