The maturity of thermal management technology for energy storage power stations

What is thermal energy storage?

Thermal energy storage (TES) technologies in the forms of sensible, latent and thermochemical heat storage are developed for relieving the mismatched energy supply and demand. Diverse TES systems are developed in recent years with the superior features of large density, long-term, durable and low-cost.

Can high-temperature phase change materials be used for thermal energy storage?

High-temperature phase change materials (PCM) candidates for thermal energy storage (TES) applications, National Renewable Energy Lab. (NREL), Golden, CO (United States). NREL/TP-5500-51446 González-Roubaud E, Pérez-Osorio D, Prieto C (2017) Review of commercial thermal energy storage in concentrated solar power plants: Steam vs. molten salts.

What is heat storage technology (TES)?

TES is a heat storage technology that collects, stores and releases heat with relatively large capacity. This feature allows the feasible integration of TES with diverse energy systems such as solar energy, wind energy, geothermal energy and industrial waste heat. With the difference in storage mechanism, TES can be classified as SHS, LHS and TCHS.

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.

What is the Technology Strategy assessment on thermal energy storage?

This technology strategy assessment on thermal energy storage, released as part of the Long-Duration Storage Shot, contains the findings from the Storage Innovations (SI) 2030 strategic initiative.

Does a PV/T/PCM system provide thermal storage potential?

Islam et al., utilized a PV/T/PCM system to provide 33% thermal storage potential compared to conventional photovoltaic hot water systems (PV/T/W) with extended thermal availability 75–100%, heat production increased by about 9%, and the cooling effect of the PV/T/PCM is also better than that of the conventional PV/T/W system.
