A plate heat exchanger is a component of efficient and low-cost energy storage systems, in particular for thermal and mechanical solutions. Alfa Laval's proven and reliable plate heat exchangers are able to handle cyclical duties with reversible flows, across a wide range of different temperatures and pressures, as well as energy storage medias.
This review highlights the latest advancements in thermal energy storage systems for renewable energy, examining key technological breakthroughs in phase change materials (PCMs), sensible thermal storage, and hybrid storage systems. Practical applications in managing solar and wind energy in residential and industrial settings are analyzed.
The main approach is coupling external heat sources to elevate the energy level of the air, consequently boosting the system's output power. Shi et al. introduced an LAES system integrated with a coal-fired unit, utilizing heat exchange between water/steam in the coal-fired unit and compressed/expanded air in the LAES system.

Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and in industrial processes.
Thus, HNePCMs are demonstrated to be more efficient materials and are emerging as potential materials to augment the performance of TES applications. The authors declare no conflict of interest. The disparity between the supply and demand for thermal energy has encouraged scientists to develop effective thermal energy storage (TES) technologies.
1) For immersed heat exchanger configurations, the phase change behavior is more significant with a higher power during the phase change. 2) Due to the high HTF fraction, the mean thermal power of the macroencapsulated system can be higher than for immersed heat exchangers even for a lower heat transfer area within the storage volume.
