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.

Can phase change materials reduce energy concerns?

Abstract Phase change materials (PCMs) can alleviate concerns over energy to some extent by reversibly storing a tremendous amount of renewable and sustainable thermal energy. However, the low ther...

How do phase change composites convert solar energy into thermal energy?

Traditional phase change composites for photo-thermal conversion absorb solar energy and transform it into thermal energy at the top layers. The middle and bottom layers are heated by long-distance thermal diffusion.

Are multifunctional composite PCMS the future of thermal storage and heat transfer?

In addition to the aforementioned thermal storage and heat transfer performance studies of EG-based composite PCMs, multifunctional composite PCMs are destined to be more popular for future applications. Integrating different functional materials is a feasible strategy.

How can dynamic PCMS achieve high-power and high-density thermal storage?

Dynamic PCMs can achieve high-power and high-density thermal storage by keeping the solid–liquid interface in close contact with the heat source and reducing the thickness of the solid–liquid interface, which is sluggish in thermal transfer.

Can thermo-economic analysis promote PCM thermal storage techniques?

The quantification of system-level costs and benefits using thermo-economic analysis has the potential to promote PCM thermal storage techniques to a variety of broad applications. Moreover, the investigation of energy and environment policy in a country or region has the potential to avoid risks or to cater to local thermal storage development.
