Can phase change materials reduce intermittency in thermal energy storage?

Thermal energy storage technologies utilizing phase change materials (PCMs) that melt in the intermediate temperature range, between 100 and 220 °C, have the potential to mitigate the intermittency...

Can bio-sourced phase change materials be used for energy storage & thermal regulation?

In recent years intensive research has been conducted on phase change materials (PCMs) for both energy storage and thermal regulation of equipment and buildings. However, a great number of PCMs are derived from fossil fuel industry such as paraffin. Thus, bio-sourced PCM can be utilized and hence contribute to achieve the sustainability goals.

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.

Why do thermal energy storage materials have a high thermal conductivity?

While these materials generally have lower latent heat than materials with a solid-to-liquid phase transformation, their significantly higher thermal conductivity enables rapid thermal charging/discharging. Here, we show that this property makes them particularly promising for thermal energy storage applications requiring highly dynamic operation.
