Should a latent thermal energy storage system be integrated?

Latent thermal energy storage systems using phase change materials are highly thought for such applications due to their high energy density as compared to their sensible heat counterparts. This review, therefore, gives a summary of major factors that need to be assessed before an integration of the latent thermal energy system is undertaken.

What are the challenges of latent thermal energy storage?

One of the main challenges for latent thermal energy storages is the phase change itself which requires a separation of the storage medium and HTF. Furthermore, PCMs usually have a low thermal conductivity, which limits the heat transfer and power of the storage.

What is latent heat thermal energy storage (lhtes)?

Latent heat thermal energy storage (LHTES) based on phase change material (PCM) plays a significant role in saving and efficient use of energy, dealing with mismatch between demand and supply, and increasing the efficiency of energy systems .

How to evaluate latent thermal energy storage performance?

Usually the latent thermal energy storage performance can be assessed with the energy analysis and exergy analysis as the following equations: The heat storage ratio, which is the ratio of the total energy stored in the system to the maximum energy stored in the system, and the heat release factor are used to evaluate energy performance.

What are sensible and latent thermal energy storage?

Sensible, latent, and thermochemical energy storages for different temperatures ranges are investigated with a current special focus on sensible and latent thermal energy storages. Thermochemical heat storage is a technology under development with potentially high-energy densities.

Which components are developed for latent thermal energy storage systems?

Furthermore, components for latent thermal energy storage systems are developed including macroencapsulated PCM and immersed heat exchanger configurations. For material development the following key points can be concluded.
