Beschreibung
Zusammenfassung:	A compressed-air energy-storage system (1) is described. The system comprises: a first compressor arrangement (3) for compressing an air stream; a thermal energy storage unit (13), where through compressed air from the first compressor arrangement (3) exchanges heat against a heat accumulation means; an air storage device (17) arranged and configured for receiving and accumulating compressed air from the thermal energy storage unit (13); at least one expander (21) for receiving compressed air from the air storage device (17) and producing useful power therefrom. A further compressor arrangement (15) is located between the thermal energy storage unit (13) and the air storage device (17).
