Thermal energy storage (TES) is a technology that reserves thermal energy by heating or cooling a storage medium and then uses the stored energy later for electricity generation using a heat engine cycle (Sarbu and Sebarchievici, 2018 ). It can shift the electrical loads, which indicates its ability to operate in demand-side management ...

At present, the main thermal energy storage types include sensible heat thermal energy storage (SHTES), LHTES, thermochemical thermal energy storage [3]. Among them, the thermal storage density of LHTES is 5–10 times higher than that of SHTES [4], and it is safer and more reliable than thermochemical thermal energy storage.
