Abstract

Nowadays, as global warming is becoming one of the world's most urgent problems, we need to find a better way to use energy, particularly in the energy storage are. Thermal energy storage is one of the recommended ways to improve energy recovery from solar energy, off-peak electricity and industrial waste heat recovery. In this paper, an overview of the Phase Change Material (PCM) experimental procedure is explored to improve its thermal conductivity. Enhancing PCM involves the use of nanoparticles that would influence the thermo-physical properties. Hence, the best candidate material as Nano fluids is preferred in order to maximize the thermal conductivity of the PCMs properties. The degree of super cooling of PCM affected by nanoparticle dispersion that can be regulated by the nanoparticle nucleation agent. In addition, the tiny structure can cause a large surface area of nanoparticles to correlate with their physical and chemical properties which lead with PCM's thermal-physical properties. Nanoparticles based on graphene are discussed in this study. The graphene surface area is the main characteristics used to determine the best thermal physical properties of material for Nanoenhanced phase change (NEPCM). Due to the best characteristics as base phase change material, inorganic salt hydrates material is reviewed in this paper. However, the use of graphene nanoparticles synthesis, characterization and modification process of nanoparticle itself to improve the thermal physical properties of inorganic PCM has been performed with limited research. The experiments in this paper are based on previous researchers by using different material of Nano fluids. The expected result of the study might be that the increasing percentage of thermal conductivity of the PCMs associated with its properties using systematic and numerical methods.
