Abstract:

Packed-bed latent thermal energy storage (PLTES) systems enable the reuse of thermal energy and efficient collection of renewable energy, making significant contributions toward achieving carbon neutrality. Considering the intricate transient nature of PLTES systems, this report begins by summarizing the numerical models employed for predicting the thermal performance of these systems. Subsequently, the performance evaluation of PLTES systems is addressed and presented together with the methodology, highlighting the advantages and distinctions between exergy efficiency analysis and energy efficiency analysis. In addition, by analyzing and summarizing the performance optimization methods applied to PLTES systems, cylindrical tanks with an aspect ratio greater than 1 are shown to be usually preferred. According to the selection of practical application scenarios, thermal oil, molten salt, and air are generally used as heat transfer fluids, and shape-stabilized phase-change materials are more promising for application. Subsequently, the report introduces the application of the PLTES system in heat recovery from industrial waste and efficient use of solar energy. Finally, prospects for the future development of PLTES systems are discussed, including areas such as tank design, heat storage unit design, operational strategies, high-temperature environments, and system cost-effectiveness. This discussion aims to provide insights and guidance to promote the development and practical application of PLTES systems.
