A comprehensive review of different thermal energy storage materials for concentrated solar power has been conducted. Fifteen candidates were selected due to their nature, thermophysical properties, and economic
This review presents potential applications of molten salts in solar and nuclear TES and the factors influencing their performance. Ternary salts (Hitec salt, Hitec XL) are found to be best suited for concentrated solar
At the end of 2019 the worldwide power generation capacity from molten salt storage in concentrating solar power (CSP) plants was 21 GWh el. 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.
Since this book is devoted to molten salt technology, the present chapter focuses on concentrated solar power (CSP) generation using molten salts in sensible and latent heat storage systems ( Table 20.1, marked bold; Figure 20.1, marked by two ellipses). Table 20.1. Overview of Salts Utilized in TES Processes
Molten salt storage research topics on CSP system level. Molten salt storage sets the commercial standard in CSP plants at the time of writing. Major indicators to evaluate and compare storage systems are the capital cost of the TES system and the LCOE. Several other TES technologies are developed for CSP.
The maximum electrical power was 11 MW. The two-tank storage system with a total volume of about 1700 m 3 had an inventory of 1400 tons of molten “Solar Salt.” The thermal capacity of the storage system was 107 MW h and the operation temperature ranged from 290 to 565 °C. This allowed for a turbine operation time of 3 h [ 94 ]. Figure 20.10.
Solar Salt is an optimized mixture with regard to melting temperature, single salt costs and heat capacity. The minimum operation temperature of Solar Salt is typically set to 290 °C (limited by the liquidus temperature of about 250 °C plus a safety margin). The maximum operation temperature is about 560 °C, mainly defined by thermal stability.
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).
