Chemical and Sorptive Thermal Storage Methods
Space heating is an important slice of the total energy consumption pie and storage of thermal heat is as important as storage of electricity. The German Fraunhofer institute has an innovation program for “chemical and sorptive thermal storage methods”.

In a sorption process, heat is stored by breaking the binding force between the sorbent and the sorbate in terms of chemical potential.
