Abstract: The scientific community largely agrees on both the potential of as well as the need for thermal energy storage (TES) in energy-efficient industrial processes. However, state-of-the-art TES technologies (latent or sensible) have one unsolved issue in common: whenever thermal energy is transferred, e.g. between the heat transfer fluid in an industrial application and the TES, the temperature of the transferred heat decreases. Consequently, even if TES systems perfectly de-couple the temporal correlation between the availability of excess heat, and, e.g., the demand for process heat, the stored heat cannot directly be re-integrated in the same process due to the temperature loss caused by two heat transfers.
