Abstract—Thermal Energy Storage (TES) using Phase Change Material (PCM) features an innovative technology for a clean and renewable energy transition. PCM is a sophisticated medium that can store huge volumes of latent heat for TES. This study demonstrates a facile synthesis of Lauric Acid (LA) based PCM hybridized with 2D nanomaterials which are Graphene Nanoplatelets (GNP) and MXene. The results showed that inclusion of GNP increases the thermal conductivity of PCM nanocomposites by 13% at a mass fraction of 1 and 3%. Differential scanning calorimeter results showed that the latent heat enthalpy reduced with the increment of GNP and MXene mass fraction, due to the reduction of LA per unit mass area. There are insignificant changes of melting temperature for LA/GNP compared to LA/MXene which is evident that addition of GNP is capable to maintain and stable the PCM temperature. Based on this study, PCM with mass fraction of 3% GNP (LA/GNP
2) exhibited the best candidate for TES application due to its trade-off between thermal conductivity and energy storage efficiency, if compared with LA hybridized with MXene (LA/Mxene).
