Utility Solar Thermal Plant Uses Molten Salt for Heat Storage

Solar Reserve to build utility-scale solar thermal plant in Nevada using molten salt for storage system.

SolarReserve has signed a deal to build a utility-scale solar thermal plant in Nevada with a molten salt storage system that will let it supply power when the sun isn’t shining.  Sounds pretty cool, huh?  So how does it work?  The solar thermal plant will use a field of heliostats–large mirrors that track the movement of the sun–to heat molten salt held in a tower. That liquid salt is heated to over 1,000 degrees Fahrenheit and transferred to storage tanks. It is then fed into a loop where it creates steam that turns a turbine to generate electricity.
