For solar power generation technologies, when water serves as the HTM, it is mainly used in the direct steam generation CSP systems 99 or some solar-based multi-energy hybrid systems (e.g., integrated solar-gas combined cycle systems 100, 101). In these CSP systems, water serves as the HTM and working fluid for the steam turbine simultaneously. It

Binary salt or solar salt is the most common material used in thermal solar plant energy storage systems. Binary salt is a mixture of 60% NaNO 3 and 40% KNO 3, which has a melting point of 222 °C; first time it was used in the two solar projects [1, 2].This project operated from 1995 to 1999 and consisted of two tanks, one cold (290 °C) and another hot (565 °C)

Molten salt in the receiver is heated by solar energy and directed to thermal energy storage or a power cycle. A more negative free energy indicates that a metal is more prone to attack, and a more positive free energy indicates a metal is less prone. From this information, it has been determined that structural alloy components are increasingly prone to
