Beschreibung
Zusammenfassung:	A system and method for thermoelectric energy storage is described. A thermoelectric energy storage system (22, 36) having a heat exchanger (30) which contains a thermal storage medium, and a working fluid circuit for circulating a working fluid through the heat exchanger (30) for heat transfer with the thermal storage medium. The working fluid undergoes transcritical cooling during the charging and transcritical heating during the discharging cycle as it exchanges heat with the thermal storage medium. Improved roundtrip efficiency is achieved through minimising the maximum temperature difference (”Tmax) between the working fluid and the thermal storage medium during operating cycles.
