Exploring Novel Combinations of Quaternary and Ternary Salts

Abstract

The advancement of heat transfer fluids (HTFs) is crucial for improving the efficiency of solar thermal energy systems, particularly in concentrated solar power (CSP) plants. This short communication highlights recent research focused on novel quaternary and ternary nitrate-based salt mixtures as HTFs. These mixtures, characterized by enhanced thermophysical properties such as higher thermal conductivity, lower melting points, and increased specific heat capacity, represent a promising solution to the limitations of traditional binary salt systems. Experimental and comparative analyses reveal significant potential for these innovative HTFs to boost CSP system performance, aligning with sustainable energy goals and the UN’s SDGs.
