Materials compatibility for the next generation of Concentrated Solar Power plants

The use of molten salts based on fluorides/chlorides/nitrates/sulfates or carbonates is now an accepted practice in energy conversion technologies and many other industrial processes. However, compatibility of molten salts with the structural alloys and materials corrosion has been of real concern at such temperatures (600–900°C). Hence, the material development and corrosion studies turn out to be an essential part of research. The results of recent studies are reviewed to understand the developments that have occurred in the latter part of the last decade. The corrosion kinetics of modern materials in variety of molten salts with focus on reaction mechanisms and corrosion products is investigated by scientists around the globe. Emphasis has also been given on the composition of the oxide films/corrosion products on alloys of interest in wide a range of melts. By and large, molten salt corrosion has been predominantly studied by gravimetric, electrochemical techniques and, morphology and chemical...

High-Temperature Corrosion Behavior of Superalloys in Molten Salts – A Review

High temperature corrosion of molten salt containment materials is of great interest for thermal energy storage systems used with concentrating solar power. Mitigating this corrosion is critical for the design, life cycle and economics of these systems and requires understanding the mechanisms which drive corrosion. In molten salts these mechanisms are complex, and heavily influenced by factors such as impurities, atmosphere, temperature and metal composition. This review aims to illustrate the mechanisms of molten salt corrosion in thermal energy storage systems and the primary factors which affect them. As these factors are so important for corrosion mechanisms, much of the published corrosion rate data will be not be applicable to many thermal energy storage systems. This means that controlling these conditions and corrosion testing will be an indispensable part of developing cost-effective thermal energy storage systems.
