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.
Are phase change thermal storage systems better than sensible heat storage methods?
Phase change thermal storage systems offer distinct advantages compared to sensible heat storage methods. An area that is now being extensively studied is the improvement of heat transmission in thermal storage systems that involve phase shift . Phase shift energy storage technology enhances energy efficiency by using RESs.
Materials with phase changes effectively store energy. Solar energy is used for air-conditioning and cooking, among other things. Latent energy storage is dependent on the storage medium's phase transition. Acetate of metal or nonmetal, melting point 150–500°C, is used as a storage medium.
1. Introduction Phase change energy storage materials (PCESM) refer to compounds capable of efficiently storing and releasing a substantial quantity of thermal energy during the phase transition process.
PCESM integration has demonstrated promise in reducing building energy consumption in materials like mortars, concrete, and solar thermal systems . Future prospects include the development of materials for heat storage with better thermal characteristics and microencapsulated PCESM optimization techniques.
PCESM provides substantial technological advancements in multiple solar energy methods, including SCs, solar stills, solar ponds, solar air warmers, and solar chimneys . Enhancing the low thermal conductivity of PCESM during phase shift is a significant obstacle.
