Advancements and Challenges in Thermal Energy Storage for Concentrated Solar Power Systems

Abstract

Thermal energy storage (TES) plays a critical role in enhancing the performance and reliability of Concentrated Solar Power (CSP) systems, offering solutions for energy supply during periods of low sunlight. This communication highlights recent advancements in TES materials, specifically focusing on molten salts, quaternary nitrate-based mixtures, and nanofluid-enhanced heat transfer fluids. We review the economic viability, environmental impacts, and the technical challenges faced in optimizing TES for CSP applications. Future prospects for improving energy storage efficiency and sustainability are also discussed.
