Opportunities of lithium nitrate as TES material in CSP plants: Thermal characterization and LCOE projection

摘要

In recent years, lithium based salts have been studied for thermal energy storage (TES) applications due to their excellent thermophysical properties. The addition of lithium nitrate is assumed to improve the performance of molten salts, extending the work temperature range. This paper presents a comprehensive review of the thermal properties reported as well as the influence of the different additions of LiNO_3 impurity grades, including a Chilean mixture obtained from the Atacama Desert brines.
