【 摘 要 】

In this review, we summarise the current status and new trends in concentrating solar power (CSP) technology, analysing the technology cost and their evolution during the last years, with special focus on thermal storage. Moreover, we have carried out a comprehensive review of the molten salts used and proposed in CSP commercial plants. Nitrates, nitrites, chlorides, and carbonates are presented, including their corrosion aspects with common alloys as well as the different possibilities available in the literature to replace them (ternary and quaternary nitrate molten salt) or improve them (addition of nano particles). Finally, we have proposed the key factors for a successful new generation of CSP plants, with special focus on high-temperature molten salts (carbonates and chloride blends) and the main important materials requirements for CSP system components.
