Abstract. Various technologies are used in thermal energy storage (TES). Depending on the type of technology used, residual thermal energy allows for the storage and use of thermal energy for certain periods of time, at scales varying from individual process, residential, public, and industrial buildings, district, town, or region.
Even though each thermal energy source has its specific context, TES is a critical function that enables energy conservation across all main thermal energy sources [5].
