Summary

To reduce the load on electric grids with the increasing usage of heat pumps (HP), thermochemical storage (TCS) integration is explored in the present study for heat discharge during peak hours. The potential of a liquid absorption based TCS with aqueous sodium hydroxide solution is considered for a domestic heating application. Three configurations of heat pump integration with the thermal storage are investigated for a typical building in UK. The optimal assessment of the thermal storage capacity and the operating temperatures has been carried out through an estimation of the thermodynamic limits and the total costs incurred over the system’s lifetime. It is observed that the cascaded configuration with the TCS discharging heat to the room and heat pump connected to the ambient, offers the highest cost savings potential of up to 16% and an annual electric power consumption reduction of over 40% in comparison to that without thermal storage.
