Title: ENERGY STORAGE SYSTEM
Abstract:
The present invention provides an energy storage system (10) for a use with a boiler (20). The energy storage system (10) comprises a plurality of thermal energy storage banks (101, 102, 103, 104). Each thermal energy storage bank(101, 102, 103, 104) comprises phase changeable material having a predetermined phase transformation temperature. The energy storage system (10) also includes an extraction device (105; 1 15) configured to recover waste energy from the boiler (20). The extraction device (105, 1 15) is operable to extract waste energy from the boiler (20) and feed that energy to at least one (101 ) of the thermal energy storage banks (101, 102, 103, 104). A controller (106) is arranged, in use, to activate the extraction device (105, 115) in response to operation of the boiler (20).
