Title: Heat transfer/storage fluids and systems that utilize such fluids

Abstract

Heat transfer/storage fluids that are resistant to oxidation in air at elevated temperatures, and systems that utilize such heat transfer/storage fluids, for example, as part of a concentrating solar power (CSP) system or other electricity-generating systems. The heat transfer/storage fluid is a molten chloride solution comprising two or more chlorides selected from the group consisting of CaCl₂, SrCl₂, BaCl₂, NaCl, and KCl.
