Abstract
Thermal Energy Storage (TES) for Concentrated Solar Power (CSP) applications is a vital part of bringing green technologies to cost parity with traditional fuel-based power. Eutectic salt mixtures are highly suitable for use in TES. However, they contain impurities that can detrimentally impact their performance and corrosion characteristics when stored in a metallic container. This review will present a summary of findings that delve into the characterization, quantification, and, most importantly, the mitigation and control of these contaminants. Some of the common impurities discovered in commercially available salts include O-2, H+ and OH-, all of which highly accelerate corrosion. Other contaminants include chloride, fluoride, perchlorate, sulfate, carbonate and nitrite/nitrate compounds. Purification, monitoring, and control of impurities are presented; including heat processing, gas sparging, additives, acid consumption analysis, voltammetry methods, and physical filtration. Finally, recommendations are made for the most appropriate strategies for mitigating impurities for CSP applications.
