Abstract
There is provided a thermal energy storage system, comprising at least two thermal storage masses, wherein an inner thermal storage mass (48) is contained within an outer thermal storage mass (49). A pump or compressor (42) forces a compressible fluid around the system. A first storage mass heat exchanger (50) has a first side in fluid communication with the pump or compressor (42), and a second side in contact with the outer thermal storage mass (49). A second storage mass heat exchanger (51) has a first side in fluid communication with the first side of the first storage mass heat exchanger (50), and a second side in contact with the inner thermal storage mass (48). A turbine (43) has a turbine inlet in fluid communication with the first side of the second storage mass heat exchanger (51), and a turbine outlet. An electrical generator is driven by the turbine (43). The system further comprises a thermal store (52) containing a thermal store medium. At least one thermal input heat exchanger (55) is located in the thermal store (52), the at least one thermal input heat exchanger having a first side adapted to receive heat from the outer thermal storage mass (49), and a second side …
