PCM thermal energy storage has been put in focus in recent years because of its ability to store more thermal energy than sensible heat storage.

Thermal energy storage (TES) can be achieved by sensible, latent or thermo chemical heat storage. Sensible heat storage relies on the material’s specific heat capacity while latent heat storage relies on the material’s phase change enthalpy to store heat within a narrow temperature range. PCM as a latent heat storage material provides greater energy density than that achievable with sensible heat storage media over the same temperature gradient.

Compared to water, PCM can store 2.5~6 times more energy. To date, PCM has been used in many industry sectors for heat or cold storage. Shanghai Tempered Entropy provides PCM for thermal energy storage system.
