Are phase change materials suitable for thermal energy storage?

Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.

Does a phase change material improve the performance of a solar still?

The use of a phase change material (PCM) as a heat storage medium enhanced the performance of a solar still. Two solar stills were developed, built, and tested in order to assess the productivity of solar desalination systems ( Fig. 6 ).

What are the benefits of phase change materials in solid-liquid form?

Phase change materials (PCMs) in solid-liquid form have the benefits of minimal volume alteration, high energy storage capacity, and appropriate phase transition temperature. They are capable of releasing and storing latent heat in a reversible manner to facilitate the storage and use of thermal energy during the transition process.

What is a PCM in energy storage?

PCMs represent a novel form of energy storage materials capable of utilizing latent heat in the phase change process for thermal energy storage and utilization , . Solid-liquid PCMs are now the most practical PCMs due to their small volume change, high energy storage density and suitable phase transition temperature.

What is a phase change material (PCM)?

A phase change material (PCM) is a substance with a high heat of fusion that, by melting and solidifying at a particular temperature, may store and release enormous amounts of energy. Because heat is either retained or released as a substance changes from solid to liquid, PCMs fall under the category of latent heat storage (LHS) units.

How do heat sources affect the heat storage power of PCMS?

Different heat sources have a large impact on the heat storage power of PCMs, and the general trend is to increase the contact area between the heat source and the solid–liquid interface to effectively improve the heat storage power.
