There are various thermal energy storage methods, but latent heat storage is the most attractive one, due to high storage density and small temperature variation from storage to retrieval. In a latent heat storage system, energy is stored by phase change, solid–solid, liquid–solid or gas–liquid of the storage medium [4].
