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.
It provides a detailed overview of thermal energy storage (TES) systems based on phase-change materials (PCMs), emphasizing their critical role in storing and releasing latent heat. Moreover, different types of PCMs and their selection criteria for electricity generation are also described.
