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.

What is thermal management using phase change materials (PCMs)?

Thermal management using phase change materials (PCMs) is a promising solution for cooling and energy storage 7, 8, where the PCM offers the ability to store or release the latent heat of the material.

How do phase change materials work?

The most common way this is done is with large batteries, however, it’s not the only game in town. Phase change materials are proving to be a useful tool to store excess energy and recover it later – storing energy not as electricity, but as heat. Let’s take a look at how the technology works, and some of its most useful applications.

How do phase change materials store energy?

Unlike batteries or capacitors, phase change materials don’t store energy as electricity, but heat. This is done by using the unique physical properties of phase changes – in the case of a material transitioning between solid and liquid phases, or liquid and gas. When heat energy is applied to a material, such as water, the temperature increases.

Can paraffin wax be used for thermal energy storage?

A paraffin wax with the melting temperature of 58–62°C was used as PCM and filled into evacuated tubes for thermal energy storage by Abokersh et al. . The heat transfer between the water and PCM was achieved by different U-tube heat exchangers with and without fins inside the evacuated tubes, respectively.

What is phase change heat storage?

By taking advantage of latent heat, large amounts of energy can be stored in a relatively small change in actual temperature, and accessed by manipulating the phase change of a material. Perhaps the most common form of phase change heat storage on the market is the sodium-acetate handwarmer.
