Applications and technological challenges for heat recovery, storage and utilisation with latent thermal energy storage

Thermal energy storage (TES) technology is considered to have the greatest potential balance demand and supply overcoming intermittency fluctuation nature of real-world heat sources, making a more flexible, highly efficient reliable thermal system. This article provides comprehensive state-of-the-art review latent (LTES) with particular focus on medium-high temperature phase change materials for recovery, utilisation. aims identify methods design optimise LTES exchangers recovery storage, bridging knowledge gap between present studies future technological developments. The key focuses current work can be described as follows: (1) Insight into moderate-high conductivity enhancement methods. (2) Various configurations relevant transfer techniques (3) Applications different including solar energy, industrial waste engine heat, are discussed in detail.
