Beschreibung
Zusammenfassung:	The present invention relates to a compressed-gas energy storage and recovery system and method, comprising:a gas compression line (1) with at least two compression stages (3), each comprising a heat storage device downstream from a compression means (100, 101, 102),in a compression stage (3), the heat storage device comprises a heat storage means (200, 201) for exclusively direct heat exchange between the compressed gas and heat storage particles, andin another compression stage (3), the heat storage device comprises a cooling loop, with an exchanger (800) for heat exchange between the compressed gas and a heat transfer fluid, and a heat storage means (203) for direct heat exchange between the heat storage particles and the heat transfer fluid.
