The rechargeable heat battery forms the core of the compact thermal storage system. Employing a thermochemical storage material, the material absorbing, and the necessary heat exchangers, pipes and valves it is a complex piece of engineering. Heat exchange and input/output power are crucial depending on the precise application. Mass-transport inside the thermochemical storage material should be optimal and well-monitored. In addition to the hardware, storage and draining strategies need to be developed so that one can make optimal use of available solar energy.


Depending on the exact size and characteristics of the heat battery, an optimal system set-up can be implemented.
