Common thermal fluids include oils and molten salts, each with distinct attributes that make them suitable for specific applications. The selection of an appropriate thermal medium is critical, as it directly impacts the efficiency and effectiveness of the solar energy conversion process.

In CSP systems utilizing thermal fluids, heat is collected through large mirrors or lens systems that concentrate sunlight onto a receiver containing the thermal medium. This concentrated heat raises the temperature of the thermal fluid, which then circulates through a heat exchanger where it transfers thermal energy to water, generating steam to drive turbines. This indirect approach not only enhances efficiency but also allows for thermal storage solutions. With molten salts, for instance, heated salt can be stored in insulated tanks, enabling energy production even during the night or cloudy conditions. This level of energy storage capability represents a significant advance, facilitating a more stable energy output.
