In Germany, approximately 55% of final energy consumption goes towards heating and cooling. However, large quantities of heat dissipate completely unused, as it is not generated at the time it is needed. Thermal storage utilising zeolite material permits heat to be accumulated for extended periods of time without any being lost. Researchers at Fraunhofer-Gesellschaft are now working towards enhancing the thermal conductivity of zeolites.
The majority of contemporary roofs have solar collectors that provide homes with warm water. In summer, this is very efficient, but the demand for heating grows to much greater levels in the winter. Consequently, thermal storage must be capable of storing excess heat for when it is needed. Typically, massive water tanks have been employed for this storage; water is heated in the tanks and the heat is stored directly as heat.
However, this technique necessitates large volumes and results in heat being lost, regardless of good insulation. Meanwhile, thermochemical storage allows for thermal energy generated in the summer to be maintained for application in the winter.
