The solid ↔ liquid PCMs are further classified as organic, inorganic, and eutectic PCMs. The organic PCMs are the most suitable material for thermal storage with solar thermal applications because of their reusability, high latent heat, low cost, and low supercooling . The organic PCMs are further classified as paraffin and fatty acids.
The solar heat storage was carried out at a medium temperature. By setting the heating temperature to 85, 95, 105 and 115 °, and the simulation time was set for 5 h, the phase transition process of paraffin wax was analyzed.

An alternative solution consists of directly using PCMs with higher thermal conductivity and latent heat. As a general rule, the heat of fusion of materials increases with melting temperature , ; thus, there is an interest on moving towards higher melting point PCMs.However, in LHTES for power generation there is a maximum temperature imposed by
