ABSTRACT
Thermal energy storage has been reported to be an attractive option for renewable-based technology. There are several ways, i.e., sensible and latent by which this can be stored and utilized but the most proficient and efficacious way of doing it is through latent heat storage. It has the advantages, i.e., the energy is stored at the constant temperature, a practically large amount of energy is stored, minimum volume change during the phase transition, etc. This provides an attractive option for the phase change materials (PCMs) to be used in several applications, i.e., solar photovoltaic system, buildings, solar water heating system, solar greenhouse, solar cookers, solar air heating, etc. This chapter discusses the various energy storage systems with a focus on thermal energy storage. The thermal energy storage with phase change materials has been discussed in detail. Finally, the application of PCMs in various systems has been provided.
