Are solid-to-solid phase transformations good for thermal energy storage?

A numerical analysis (using an experimentally validated numerical model) has revealed that some materials with solid-to-solid phase transformations offer an excellent capacity-power trade-off for thermal energy storage applications compared to the corresponding conventional phase change materials.

How can a PCM store thermal energy efficiently?

By controlling the temperature of phase transition, thermal energy can be stored in or released from the PCM efficiently. Figure 1B is a sche-matic of a PCM storing heat from a heat source and transferring heat to a heat sink.

How can thermal energy storage be achieved?

Thermal energy storage can be achieved through 3 distinct ways: sensible; latent or thermochemical heat storage. Sensible heat storage relies on the material’s specific heat capacity.
