Solar + Salt = Energy
Nov-06-09
A Californian company, SolarReserve, is developing a solar power system that can store solar energy by focusing mirrors onto millions of gallons of molten salt, allowing the plant to provide electricity 24 hours a day.A massive circular array of mirrors focus the sun's energy on a receiver on top of a 100' tower in the center of the array. The receiver holds 4.4 million gallons of molten salt, which is heated to over 1,000 degrees.
The heat is released by passing the molten salt through a steam generator that drives a turbine to produce electricity. The cooled salt is then recirculated to the receiver for re-heating.
