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.

How to maximize the performance of a phase change heat storage device?

Hence, to maximize the performance of the phase change heat storage device, coupling the multistage PCM package with other enhanced heat transfer methods is often necessary. Li37introduced a novel thermal energy storage approach that utilizes CLHS to mitigate thermal energy losses in an adiabatic compressed air energy storage system.

Why is enhanced heat transfer important in phase change thermal storage devices?

However, there are also issues such as the small thermal conductivity of phase change materials (PCMs) and poor efficiencyin heat storage and release, and in recent years, enhanced heat transfer in phase change thermal storage devices has become one of the research hotspots for optimizing thermal storage devices.

What are heat storage methods for solar-driven cross-seasonal heating?

Heat storage methods for solar-driven cross-seasonal heating include tank thermal energy storage (TTES), pit thermal energy storage (PTES), borehole thermal energy storage (BTES), and aquifer thermal energy storage (ATES) 14, 15, 16. As heat storage volume increases, hot water preparation costs and heat loss per unit volume decrease.

Are phase change thermal storage devices better than sensible heat storage devices?

ABSTRACT: In comparison with sensible heat storage devices, phase change thermal storage devices have advantages such as high heat storage density, low heat dissipation loss, and good cyclic performance, which have great potential for solving the problem of temporal and spatial imbalances in the transfer and utilization of heat energy.

What are the different types of thermal energy storage systems?

Thermal energy storage (TES) systems store heat or cold for later use and are classified into sensible heat storage, latent heat storage, and thermochemical heat storage. Sensible heat storage systems raise the temperature of a material to store heat. Latent heat storage systems use PCMs to store heat through melting or solidifying.
