In Phase changing materials (PCMs) thermal energy is stored in the form of latent heat. The latent heat storage method offers higher storage density, with a predefined temperature difference between releasing and heat storing. This paper reviews previous work on heat storage in the form of latent heat and provides awareness to latest efforts to develop new modules of PCM for use in energy storage. Three aspects have been the focus of this review: PCM materials, encapsulation and applications. There are large numbers of PCM that solidify and melt at a wide range of temperatures, making them attractive in a number of applications. Some PCM are economical and have moderate thermal energy storage density but low thermal conductivity and, hence, require large surface area. Inorganic PCM have larger energy storage density and higher thermal conductivity but experience supercoiling and phase segregation, and hence, their application requires the use of some thickening and nucleating agents. As the renewable energy is only available during the day, PCM can be quite helpful to fulfil the need of energy during the night-time. The main advantages of PCM encapsulation are providing large heat transfer area, reduction of the PCMs reactivity towards the outside environment and controlling the changes in volume of the storage materials as phase change occurs. In this paper authors reviewed the applications of heat storage by using different PCMs with appropriate methods.
