Abstract: This article reviewed the use of phase change materials (PCM) as thermal energy storages (TES) as they can be used to substitute large-scale energy demand and assist both economically and environmentally. The thermophysical properties of different phase change materials were studied to assess their viability for thermal storage systems. One of their most common problems with using PCMs is their poor heat transfer rates. This was seen when the transient plane source (TPS) technique was used to measure the thermal conductivity of pure eicosane with eight different fractions (0, 1, 2, 3.5, 5, 6.5, 8 and 10 wt%) of CuO nanoparticles. It was observed that the ice-water bath solidified eicosane–CuO samples consistently exhibited lower values of thermal conductivity, and the samples with oven solidification exhibit higher thermal conductivity values.
