In this work, we describe the characterization of Erythritol as a phase change material by adding 0.5% and 1% mass fraction of Alumina as a nanoparticle. First, we examined the effect of thermal cycling on the chemical stability of erythritol by adding nanoparticle in FT-IR and XRD. Second, we investigated the thermal stability of erythritol by adding nanoparticle in DSC. In this experiment we performed 50 cycle’s test of melting and solidification on erythritol with 0.5 % and 1.0 % mass fraction of alumina nanoparticles. Erythritol has a melting temp 117℃ and heat of fusion 340 J/g, and, thus it is more attractive PCM in a medium Temperature Range Thermal energy storage system. The experimental result in FT-IR indicated that the mixture of Erythritol and alumina composition is stable in 0.5wt % and 1% of mass fraction. In DSC we found that After 50 cycles Erythritol with alumina nanoparticles with 0.5 and 1.0 wt. % it was showing decrease of 5.97 and 9.8% in heat of fusion respectively.
