Thermal energy storage development prospects

Why is thermal energy storage important?

Thermal energy storage (TES) can help to integrate high shares of renewable energy in power generation, industry and buildings. This outlook identifies priorities for research and development. Transforming the global energy system in line with global climate and sustainability goals calls for rapid uptake of renewables for all kinds of energy use.

What is the optimum design for thermal energy storage?

The optimum design was determined on the basis of combined objective function and it was concluded that the design with 24 fins, each of 1 mm thickness and 7 mm height is the optimum design. Kumar and Saha (2020) experimentally and numerically studied a shell and tube latent heat thermal energy storage using high porosity metal matrix as TCE.

Are Japan's research efforts in thermal energy storage a late start?

It was only in the period from 2019 to 2021 that Japan's research efforts in thermal energy storage slightly increased, indicating a relatively late start in the research of thermal energy storage, and research efforts from various economies are gradually entering this field.

How to design a thermal energy storage system?

Above all, an optimal design of thermal energy storage requires an assessment of operating temperature, optimum heat loss, thermal efficiency and insulation cost (Ward et al. 2016). Effective techniques of insulation and preventing radiative losses should be sought through further research.

Do thermal storage devices increase the value of CSP?

Furthermore, the authors claim that the addition of thermal storage devices considerably boosted the value of CSP since, under the correct operational conditions, this combination enables the installation to supply electricity 24 hours a day, meeting much higher energy demands. 1.3. TES Technologies in CSP

Which thermal storage technology has the greatest energy density?

TCES has the greatest energy density among the three thermal storage technologies, but it has a complicated control process in the application of heat storage. The main limitations of TCES materials are the low thermal conductivity, poor heat and mass transfer property, bad thermal cycling stability.
