8.6: Applications of Phase Change Materials for Sustainable Energy
Thermal energy can be stored as a change in the internal energy of certain materials as sensible heat, latent heat or both. The most commonly used method of thermal energy storage is the sensible heat method, although phase change materials (PCM), which effectively store and release latent heat energy, have been studied for more than 30 years.

How PCMs Work | Phase Energy Ltd
PCMs absorb and release thermal energy as they transition between solid and liquid states i.e. melting and freezing or crystallisation. (Transitions such as liquid-vapour-liquid also involve large thermal energy changes and are used in e.g. refrigeration circuits where vapour can be controlled.) The key to how they work is the phase change.
