Phase change storage stores more heat in less material than sensible thermal storage systems, making it an attractive option for CSP. Phase change materials (PCM) undergo melting and so store heat in the molten material.
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.
Phase Change Material (PCM); Thermal Energy Storage (TES). Thermal energy storage (TES) is defined as the temporary holding of thermal energy in the form of hot or cold substances for later utilization . Energy demands vary on daily, weekly and seasonal bases.
The phase change temperature of PCMs usually varies between 18 °C and 30 °C, but there are some applications with higher temperatures, between 37 °C and 43 °C, according to climate changes and particular needs.
Phase change materials (PCM) are “Latent” heat storage materials. The thermal energy transfer occurs when a material changes from solid to liquid, or liquid to solid. This is called a change in state, or “Phase.” Initially, these solid–liquid PCMs perform like conventional storage materials, their temperature rises as they absorb heat.
We also identify future research opportunities for PCM in thermal energy storage. Solid-liquid phase change materials (PCMs) have been studied for decades, with application to thermal management and energy storage due to the large latent heat with a relatively low temperature or volume change.
