Abstract

Thermal energy storage (TES) using phase change materials (PCM) is very promising to meet future energy needs because of its high storage capacity and low cost. This study aims to develop Jatropha oil as a new candidate for solid-liquid latent heat energy storage for cold storage applications. The characteristics of Jatropha oil as a candidate for PCM were tested experimentally using T-history methods. The test results show that Jatropha oil as a PCM candidate does not undergo super-cooling or super-cooling is very small compared to tap water and mineral water of 10 K and 15 K. The phase transition temperature of Jatropha oil ranges from -14 ºC to -16 ºC, lower than with tap freezing point and mineral water at 0 ºC. Thus, the candidate PCM has good thermal properties that can meet the thermal energy storage requirements for cold storage applications.
