The storage capacities of latent heat storage (LHT) are larger than that of the sensible heat storage (SHS), as the LHT indicates both sensible heat and phase change storage [2]. To store energy in a phase changing material, it should first experience heating, which causes the material to absorb the energy from its surrounding.
