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.
Among the various non-equilibrium properties relevant to phase change materials, thermal conductivity and supercooling are the most important. Thermal conductivity determines the thermal energy charge/discharge rate or the power output, in addition to the storage system architecture and boundary conditions.
Phase change materials (PCMs), which are commonly used in thermal energy storage applications, are difficult to design because they require excellent energy density and thermal transport, both of which are difficult to predict from simple physics-based models.
At large times, the flux is especially dependent on the thermal conductivity and heat capacity of the liquid. To extract the heat from the phase change front, it must be propagated through the liquid phase to the boundary at which the heat is collected.
: Fatty acids are a distinguished category of phase change materials (PCM). However, their inferior thermal conductivity value restricts their potential for thermal energy storage system. Carbonaceous nanomaterials have emerged as promising thermal conductivity enhancer materials for organic PCMs.
The quantification of system-level costs and benefits using thermo-economic analysis has the potential to promote PCM thermal storage techniques to a variety of broad applications. Moreover, the investigation of energy and environment policy in a country or region has the potential to avoid risks or to cater to local thermal storage development.
