For low-temperature areas such as refrigeration, cold-chain logistics, and specific medical applications, phase change materials (PCM) are particularly valuable due to their high latent heat capacity and reversible phase transitions. However, finding PCM that are not only efficient and reliable, but also environmentally safe, remains a challenge. In this work we present the work done with several adipates and alkanes towards their use as PCM for low-temperature thermal energy storage.engThermal Energy Storare (TES)AlkanesAdipatesPhase diagramPhase-change materialsPCMA thermodynamic journey: unlocking cold thermal energy storage with phase equilibrium studiesconference object
