Molten salt corrosion mechanisms of nitrate based thermal energy storage materials for concentrated solar power plants: A review
MetadataShow full item record
Corrosion mechanisms for current heat transfer fluid and storage media used in CSP plants working at temperatures from 300°C to 600°C are reviewed in this paper. The studies found in the literature show that these mechanisms are influenced by the impurities present in the salt and the relation between Mg(NO3)2, moisture, CO2, perchlorates, and sulphates with the corrosion process. Corrosion mechanisms were identified along with a discussion of the corrosion products and their influence on the corrosion layers formed.

Cathodic Protection Using Aluminum Metal in Chloride Molten Salts as Thermal Energy Storage Material in Concentrating Solar Power Plants Fernández, Ángel G.; Cabeza, Luisa F. (MDPI, 2020)The new generation of concentrated solar power (CSP) plants to be developed presents a great challenge related to the increase in maximum operating temperature since molten salt CSP technologies require alternative salt ...
Prieto, Cristina; Cooper, Patrick; Fernández Renna, Ana Inés; Cabeza, Luisa F. (Elsevier, 2016)To be able to extend the operation of a solar power plant (CSP) up to 15 h, thermal energy storage (TES) is necessary. But TES also provides more versatility to the plant and makes its reliance during operation hours more ...
Embodied energy and cost of high temperature thermal energy storage systems for use with concentrated solar power plants Jacob, Rhys; Belusko, Martin; Fernández Renna, Ana Inés; Cabeza, Luisa F.; Saman, Wasim; Bruno, Frank (Elsevier, 2016)The intermittency of renewable energy systems remains one of the major hurdles preventing a large scale uptake of these technologies and concentrated solar power (CSP) systems are no different. However, CSP has the benefit ...
