Abstract

Thermal energy storage is crucial for balancing energy demand and supply, maintaining system stability, and enhancing the utilization of intermittent renewable energy sources. Phase Change Material (PCM)-based thermal energy storage has significant potential to meet large-scale energy demands while providing economic and environmental benefits. This paper reviews research focused on improving heat transfer between PCM and hot fluid in shell and tube Latent Heat Thermal Energy Storage (LHTES) units. It concludes that in LTES systems with multiple Heat Transfer Fluid (HTF) tubes, heat transfer can be enhanced by orienting the tubes in an upward and downward V shape. Additionally, incorporating various fin shapes increases the PCM melting rate. Splitting a single inner tube into multiple tubes also improves heat transfer efficiency.
