Thermal power phase change energy storage peak load regulation

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 phase change material (PCM) based thermal energy storage?

Bayon, A. ∙ Bader, R. ∙ Jafarian, M. 86. Phase change material (PCM)-based thermal energy storage significantly affects emerging applications, with recent advancements in enhancing heat capacity and cooling power.

What is a dynamic thermal storage strategy?

For example, combined heat and power (CHP) systems for recovering and using waste heat can synchronously generate electricity and heat.86 To regulate the heat load from the CHP system, a dynamic thermal storage strategy is desired to enable an enhancement by considering the transient waste heat and dy-namic electricity generation.

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 optimize energy storage & release?

First, the charging or discharging rate for ther-mal energy storage or release should be maximized to enhance efficiency and avoid superheat.

What is a composite phase change material thermal buffer?
