A review on energy conservation in building applications with thermal storage by latent heat using phase change materials Energy Convers. Manag., 45 ( 2 ) ( 2004 ), pp. 263 - 275, 10.1016/s0196-8904(03)00131-6
Among the many energy storage technology options, thermal energy storage (TES) is very promising as more than 90% of the world''s primary energy generation is consumed or wasted as heat. 2 TES entails storing energy as either sensible heat through heating of a suitable material, as latent heat in a phase change material (PCM),

Each phase change absorbs energy from the surroundings, meaning, it makes the air cooler in the process. The principle behind phase change building materials is to take advantage of that process. So, if you have something in your home that changes phase at room temperature, you can to a degree, regulate the temperature of your home
Materials with solid-liquid phase change, which are suitable for heat or cold storage applications, are commonly referred to as phase change materials (PCMs). In this context, PCMs appear as a potential solution to increase the thermal regulation in buildings since they can storage more energy, in the latent form, than typical sensible

However, the tendency of organic phase change materials to leak out during the phase transition process, limits their practical applications in thermal energy storage. The shape-stabilization is an effective strategy to prevent the leakage and enhance the energy storage capacity of organic phase change materials.

Latent thermal energy storage using phase change materials (PCMs) could provide a solution to that problem. PCMs can store large amounts of energy in small volumes, however, the main issue is the low conductivity of PCMs, which limits the rate that energy can be stored due to the slow melting and solidification processes.
