The exciting technology in present days is storage of energy in a appropriate form and which can be conservatively converted in the required form. There is mismatch in supply and demand of energy which reduces by the energy storage and also improves the reliability and performance. When the substance change the form from one phase to another due to melting or freezing the energy stored in the substance is latent heat which is one form of thermal energy. Paraffin wax is widely used for latent heat thermal energy storage system uses because of the large latent heat and also desirable thermal properties. It has lower heat transfer rate during melting and freezing processes because of its inherent low thermal conductivity. In this work solidifications and melting performance of paraffin wax dispersed with alumina (AL2O3) and copper oxide (CuO) 100 um average size in latent heat storage system is investigate experimentally.
