Criteria of design of heat exchangers for various thermal energy storage applications along with their various components are being elaborated.

What is a heat exchanger in thermal energy storage?

On the other hand, the heat exchanger in thermal energy storage corresponds to the structure obtained after morphing through which energy flows from a source, usually the thermal fluid, to the storage material (e.g. a solid or a phase-change material, PCM).

Why are heat exchangers a problem in thermal energy storage?

Still, the main challenge is the design of heat exchangers, as the engineering system that enables the flow of energy from the sources (renewable and non-renewable) to the TSM, disregarded in recent comprehensive reviews on thermal energy storage [ 6, 7 ].
