A review of solar chemical thermal energy storage technology

What are the latest advances in thermal energy storage systems?

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.

Why is thermal storage important in a solar system?

Thermal storage plays a crucial role in solar systems as it bridges the gap between resource availability and energy demand, thereby enhancing the economic viability of the system and ensuring energy continuity during periods of usage.

Can thermochemical solar energy be used for solar thermal energy storage?

The successful projects carried out by PROMES-CNRS, ETH, EPFL, NREL, CSIRO, IMDEA, U. de Sevilla, and PSA, among others, have shown that thermochemical solar energy can be used for solar thermal energy storage in a wide range of temperatures and produce sustainable fuels [ , , ].

Why is thermal energy storage important in a CSP system?

In that context, thermal energy storage technology has become an essential part of CSP systems, as it can be seen in Fig. 13, and has been highlighted over this review. Despite the total installed cost for CSP plants with TES tends to be higher than those without, storage also allows higher capacity factors.

Can solar energy be stored as chemical energy?

The solar energy from the solar field can be potentially stored as chemical energy, through the endothermic fuel oxidation reaction in a chemical process. Thermochemical systems commonly require higher temperatures to initiate the energy storage, but conversely provide higher temperatures on the release of that energy.

Can thermochemical materials be used for energy storage?

Establish selection criteria for thermochemical materials for energy storage in solar tower power generation systems. Effect on the chemical kinetics due to the thermophysical characteristics of the inert gas used. This work emphasizes the importance of thermal energy storage and the ways to do it: by sensible, latent, and thermochemical heat.
