This article gives an overview of molten salt storage in CSP and new potential fields for decarbonization such as industrial processes, conventional power plants and electrical energy storage.
What are the advantages of molten salt solar power tower station?
The molten salt solar power tower station equipped with thermal energy storage can effectively compensate for the instability and periodic fluctuation of solar energy, and a reasonable operation control strategy is essential for its peak-regulating operation mode.
Can molten salts be used to generate concentrated solar power?
This book focuses on concentrated solar power (CSP) generation using molten salts in sensible and latent heat storage systems. Molten salts are used in various thermal energy storage (TES) processes, as shown in Table 20.1.
Can molten salt storage be used as a peaking power plant?
Drost proposed a coal fired peaking power plant using molten salt storage in 1990 112. Conventional power plant operation with a higher flexibility using TES was examined in research projects (e.g., BMWi funded projects FleGs 0327882 and FLEXI-TES 03ET7055).
Can molten salt be used for energy storage?
Large tracking mirrors, called heliostats, follow the sun throughout the day, reflecting and concentrating sunlight onto the top of Crescent Dunes' central tower. Molten salt’s physical and thermal properties make it a particularly good candidate for energy storage.
