ABSTRACT
Solar energy is a vast renewable energy source, but uncertainty in the demand and supply of energy due to various geographical regions raises a question mark. Therefore, the present manuscript includes a review to overcome this uncertainty by utilizing various thermal energy storage systems. Phase change material is the most preferred thermal energy storage system because of its high-energy storage density. The low thermal conductivity is the critical problem in phase change material that can be overcome by integrating metallic foam, carbon fiber, and metallic fins in the phase change material container. The inclusion of metallic foam limited to 0.1-3% of the Phase change material (PCM) weight leads to a slight change in thermal conductivity but a high cost. It was also seen that the addition of carbon 0.1 to 9% of the PCM weight could improve the performance of PCM. The inclusion of a metallic fin improves the thermal conductivity with the various shapes and sizes of the fin. It is found that metallic foam composites have better performance than carbon composite and metallic fin inclusion.
