Latent Heat Thermal Storage (LHTS) for Energy Sustainability
Materials with latent heat are named as latent heat storage material or simply PCM (Mehling and Cabeza 2007 ). These materials can be used for heat or cold storage. In order to use these materials to store thermal energy, the latent heat property of PCM is an important factor for suitable applications.

The operation process of the LHS tank includes two parts, which are the heat storage and heat release processes. During the heat storage process, the hot heat transfer fluid flows into the tank and pushes the cold heat transfer fluid out of the tank, thus allowing the hot heat transfer fluid and thermal energy to be stored in the tank.

Latent heat storage systems are often said to have higher storage densities than storage systems based on sensible heat storage. This is not generally true; for most PCMs, the phase change enthalpy Δh pc corresponds to the change in sensible heat with a temperature change between 100–200 K, so the storage density of sensible …
