Phase change energy storage clean heating demonstration project

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 supercooling to realize long-duration storage and intelligent release of latent heat, inspiring the design of advanced solar thermal fuels.

How do heat sources affect the heat storage power of PCMS?

Different heat sources have a large impact on the heat storage power of PCMs, and the general trend is to increase the contact area between the heat source and the solid–liquid interface to effectively improve the heat storage power.

Can dynamic PCMS stabilize heat sources at 3 kW cm –2?

It has been verified that dynamic PCMs can stabilize the temperature of heat sources at heat fluxes approaching 3 kW cm –2 in the simulation, demonstrating their promising thermal management performance.

What is a heat source driven PCM?

In the heat-source-driven mode, the heat source moves in close proximity to the liquid–solid interface. These charging processes prevent overcharging of the PCM’s liquid phase while storing the majority of absorbed heat as latent heat. As a result, it is possible to swiftly melt the entire bulk of the PCM and produce significant power.

How does cutoff temperature affect energy storage density?

For the certain power, an increase in the cutoff temperature will effectively improve the energy storage density due to the higher average temperature difference between the heat source and PCM.

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.
