Belgrade Phase Change Energy Storage Products

Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.

1. Introduction Phase change energy storage materials (PCESM) refer to compounds capable of efficiently storing and releasing a substantial quantity of thermal energy during the phase transition process.

Materials with phase changes effectively store energy. Solar energy is used for air-conditioning and cooking, among other things. Latent energy storage is dependent on the storage medium's phase transition. Acetate of metal or nonmetal, melting point 150–500°C, is used as a storage medium.

Phase Change Materials (PCMs) are ideal products for thermal management solutions. This is because they store and release thermal energy during the process of melting & freezing (changing from one phase to another). When such a material freezes, it releases large amounts of energy in the form of latent heat of fusion, or energy of crystallisation.

In phase change thermal energy storage technology, PCMs play a crucial role in determining the performance of the energy storage system. Researching and finding safe, reliable, high energy density, and high-performance PCMs is key to the advancement of phase change thermal energy storage technology. 2.2. Principles for selecting PCMs

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 shift energy storage technology enhances energy efficiency by using RESs.
