Phase change material (PCM) with shaped stabilized method for thermal energy storage: A review

Abstract

Utilization of thermal energy storage (TES) is a solution that can be used to overcome the problem of increasing levels of energy consumption. TES is a technology to improve energy efficiency by using effective heat sources that utilize latent heat and sensible heat. Phase Change Material (PCM) is a TES material that is capable of storing large amounts of heat by using small volumes. But as a TES, PCM still has weaknesses such as low thermal conductivity and leakage during the phase change process. The solution to overcome this problem is with the Shape Stabilized Phase Change Material (SSPCM) consists of PCM and supporting materials. Based on various methods of SSPCM it is known that vacuum impregnation is a method that is capable of producing stable PCM by removing gas and moisture in the pores and then injecting PCM into its supporting material. The results obtained by treating vacuum impregnation for shape stabilized on PCM can increase the value of thermal conductivity and prevent leakage. This shows that the shape stabilized method is a very important process to produce PCM that is ready to be applied with optimal and stable characteristics.
