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 energy storage (TES) with phase change materials (PCM)?

Thermal energy storage (TES) with phase change materials (PCM) was applied as useful engineering solution to reduce the gap between energy supply and energy demand in cooling or heating applications by storing extra energy generated during peak collection hours and dispatching it during off-peak hours .

Can PCM be used in thermal energy storage?

We also identify future research opportunities for PCM in thermal energy storage. Solid-liquid phase change materials (PCMs) have been studied for decades, with application to thermal management and energy storage due to the large latent heat with a relatively low temperature or volume change.

How to choose a PCM based on phase change temperature?

After the phase change temperature, the most suitable PCMs will be selected based on the melting enthalpy, and the thermal conductivity. The first property will indeed affect the energy density thus determining the compactness of the TES.

What is a phase change material (PCM)?

2. Phase change material (PCM) PCMs are types of material that may keep a massive quantity of heat at a nearly consistent temperature while transitioning from one step to the next. They have the ability to store heat energy in both sensible and latent forms.

What is a PCM & how does it work?

Recently PCMs are growing in the global market of smart materials at a considerable rate of 20% annually . As phase change phenomena happen in PCMs, they are used as thermal energy storage devices due to the high amount of energy that can be stored in the form of latent heat.
