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.

Are hnepcms effective thermal energy storage materials?

Thus, HNePCMs are demonstrated to be more efficient materials and are emerging as potential materials to augment the performance of TES applications. The authors declare no conflict of interest. The disparity between the supply and demand for thermal energy has encouraged scientists to develop effective thermal energy storage (TES) technologies.

Are hybrid nano-enhanced phase-change materials suitable for thermal energy storage?

The disparity between the supply and demand for thermal energy has encouraged scientists to develop effective thermal energy storage (TES) technologies. In this regard, hybrid nano-enhanced phase-change materials (HNePCMs) are integrated into a square enclosure for TES system analysis.

Why are phase-change materials important for energy storage?

When a phase-change material (PCM) undergoes a transition between solid and liquid states, or when its internal structure changes, it either absorbs or releases significantly more energy compared to sensible heat storage. As a result, PCMs are invaluable for energy storage.

Why is graphene a good energy storage material?

The reduction in supercooling increased the composite material’s energy storage capacity by 157.6 kJ/kg, which is 101.4% higher than expected. Graphene, with its high thermal conductivity and photothermal responsiveness, effectively controls thermal radiation and absorbs solar light from visible to near-infrared.
