The choice of storage material significantly impacts the systems performance and cost. Water is readily available and inexpensive, but less efficient for high-temperature applications. Molten salts offer higher storage capacity at higher temperatures, making them suitable for CSP plants. Rocks are another option, particularly for lower-temperature applications where cost is a primary consideration.




• Latent Heat Storage: This method utilizes phase-change materials (PCMs) that absorb or release significant amounts of energy during phase transitions (e.g., solid to liquid). PCMs generally offer higher energy density than sensible heat storage, but can be more expensive and have shorter lifespans depending on the material used. Research continues to focus on developing more robust and cost-effective PCMs.




• Thermochemical Storage: This approach stores energy through reversible chemical reactions. While offering potentially very high energy density and long storage durations, thermochemical storage systems are currently less mature and often more complex and expensive. Ongoing research is aimed at improving their efficiency and cost-competitiveness.
