SolarReserve’s industry leading CSP technology features an integrated molten salt energy storage system, allowing firm, reliable electricity to be generated on-demand and delivered when the client requests the electricity. This energy storage capability provides a stable electricity product similar to that of conventional fuel-burning power facilities, but without the associated harmful emissions and price volatility.

Engineered and proven by Pratt & Whitney Rocketdyne, the technology generates power from sunlight by focusing energy from a field of sun-tracking mirrors called heliostats onto a central receiver. Liquid salt, which flows similarly to water when melted, is circulated through the receiver, collecting the energy gathered from the sun. The heated salt is then routed to an insulated storage tank where it is stored with minimal energy losses. When electricity is needed, the hot salt is routed to heat exchangers to produce steam that is then used to generate electricity in a conventional steam turbine cycle. Therefore, the system minimizes risk, time and cost, while providing high capacity storage that allows energy production on-demand, day or night.
