Abstract:
1. A thermoelectric energy storage system having a charging cycle for providing thermal energy to a thermal storage, and a discharging cycle for generating electricity by retrieving the thermal energy from the thermal storage, the thermoelectric energy storage system comprising; a working fluid circuit for circulating a working fluid through a first heat exchanger and a second heat exchanger; a thermal storage medium circuit for circulating a thermal storage medium, the thermal storage medium circuit having at least one hot storage tank coupled to a cold storage tank via the first heat exchanger; wherein, during a charging cycle, the second heat exchanger is connected to a first thermal bath and a temperature difference between the first thermal bath and a hot storage tank is minimized, and wherein, during a discharging cycle, the second heat exchanger is connected to a second thermal bath and a temperature difference between the second thermal bath and the hot storage tank is maximized.
