Advancements in Hybrid Heat Transfer Fluids: Potential for Reduced Melting Points in CSP Applications

Abstract

This short communication explores recent advancements in hybrid heat transfer fluids (HTFs) for concentrated solar power (CSP) applications, focusing on their potential to reduce melting points. We examine the development of novel hybrid HTF formulations, including nanofluid-enhanced molten salts and multi-component mixtures, and their impact on thermophysical properties. The study highlights the benefits of reduced melting points for CSP system efficiency, operational flexibility, and cost reduction, while also addressing challenges in long-term stability and scalability.
