Thermal storage for the energy transition

The energy is not stored in the form of increased heat but in the form of a chemical state

05-Oct-2021 - In Germany, 55 percent of final energy consumption goes towards heating and cooling. However, a lot of heat dissipates unused because it is not generated as and when required. Thermal storage using zeolite material allows heat to be stored for long periods of time without losing any. Fraunhofer ...
