Abstract
The invention is directed to energy storage and supply system (100) comprising a combination of a heat pump (HP) (2) and a thermochemical storage (TCS) (1) unit, adapted for storing and supplying energy. In a further aspect, the invention is directed to a method for operating the energy storage and supply system (100), wherein said method comprises charging and discharging phases which both comprise providing a HP warm stream by the HP and leading said HP warm stream to the TCS unit to respectively thermally charge and discharge said TCS unit.

Method for operating an energy storage and supply system (100) comprising a combination of a heat pump (HP) (2) and a thermochemical storage (TCS) (1) unit, wherein said method comprises charging and discharging phases which both comprise providing a HP warm stream by the HP and leading said HP warm stream to the TCS unit to respectively thermally charge and discharge said TCS unit.
Energy storage and supply system (100) comprising a combination of a heat pump (HP) (2) and a thermochemical storage (TCS) (1) unit, adapted for storing and supplying energy with a method in accordance with any of the previous claims, adapted such that the HP can be in thermal connection to the TCS unit and a HP warm stream generated by the HP can be led to the TCS unit, preferably to an energy storage compartment (11) and/or a liquid storage compartment (12) of said TCS unit, wherein said energy storage compartment comprises a sorption material (14) adapted such that it can be charged with heat via a first TCS heat exchanger (13) that is in thermal connection to a HP condenser (21) in said HP, wherein the liquid storage compartment comprises a second TCS heat exchanger (15) which is in thermal connection to both said HP condenser (21) and a HP evaporator (22) via a HP heat exchanger (24) and wherein said TCS unit further comprises a valve unit (16) which can be closed during storage of the thermal energy.
