Abstract In the development of renewable energies, thermal energy storage (TES) has become a key opportunity to relieve to some extent the increase in energy demand and supply. The past two decades have seen increasingly advances in the field of phase change materials (PCM) as latent heat storage systems, being one concern their containment when using solid to liquid PCM. The purpose of this paper is to review the state-of-the-art of shape-stabilization (SS-PCM) and encapsulation (CS-PCM) of organic PCMs for low thermal applications (
