Global Cumulative Installed Concentrated Solar Power Capacity with Thermal Energy Storage System and Cost Trend

Abstract

Thermal Energy Storage (TES) is essential for enhancing the dispatchability and efficiency of Concentrated Solar Power (CSP) systems. This short communication reviews recent advancements in TES technologies for CSP, focusing on novel storage materials, system designs, and implementation challenges. We explore innovations in molten salt formulations, solid-state storage media, and thermochemical storage systems. Key practical aspects such as system integration, cost considerations, and operational challenges are also discussed. Significant progress has been made in high-temperature TES systems, with potential for further cost reductions and efficiency improvements in the coming years. This review provides insights into the current state of TES in CSP and outlines future research directions for performance enhancement and cost reduction
