6 FAQs about [Energy storage capacity of phase change thermal storage]

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 the thermal storage behavior of a PCM?

Thermal storage behavior of the PCM is compared with pure Cu for (D) heat source temperature (Tsource), (E) stored heat flux (q″stored), and (F) stored energy (E). The temperatures and zones at which melting or solidification occur are key parameters for PCMs. Superheating rarely occurs in PCMs.

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.

How to improve thermal capacity and power in latent heat storage systems?

To improve the trade-off between thermal capacity and power in conventional latent heat storage systems, additives (e.g., nanoparticles, carbon nanotubes, etc.) and extended surfaces (e.g., fins, aerogels, metal matrix, etc.) are typically used, 10 but this comes at an additional cost to the system.

How does a PCM control the temperature of phase transition?

By controlling the temperature of phase transition, thermal energy can be stored in or released from the PCM efficiently. Figure 1 B is a schematic of a PCM storing heat from a heat source and transferring heat to a heat sink.

Can spatiotemporal phase change materials be used for solar thermal fuels?

In a recent issue of Angewandte Chemie, Chen et al. proposed a new concept of spatiotemporal phase change materials with high super-cooling to realize long-duration storage and intelligent release of latent heat, inspiring the design of advanced solar thermal fuels.
