Solar power generation around the clock

-snip-

A Californian company, SolarReserve, is developing a solar power system that can store seven hours' worth of solar energy by focusing mirrors onto millions of gallons of molten salt, allowing the plant to provide electricity 24 hours a day.

The salt used is a mixture of sodium and potassium nitrate (the same as that used in fertilizers), which is cheap, reliable, and environmentally friendly. It will be mixed on site with no additives. Apart from a few unique components such as the high heat flux hardware in the tower, the system uses existing technologies such as turbines and steam generators. This means SolarReserve can produce electricity at prices equivalent to or below fossil fuel burning plants.

The system was proven over a four-year period in the 1990s at the 10-megawatt Solar Two demonstration project near Barstow in California.
