Phase change thermal storage systems offer distinct advantages compared to sensible heat storage methods. An area that is now being extensively studied is the improvement of heat transmission in thermal storage systems that involve phase shift .

Phase change thermal energy storage technology utilizes phase change materials (PCMs) to store energy by absorbing or releasing a large amount of latent heat during the phase transition process. As shown in Fig. 4, the phase change process typically includes solid-solid phase change, solid-liquid phase change, and gas-liquid phase change.
Phase change materials (PCMs) included in building elements such as wall panels, blocks, panels or coatings, for heating and cooling applications have been shown, when heating, to increase the heat storage capacity by absorbing heat as latent heat.
