A Solar-Powered Oil Field?

BrightSource Energy has broken ground on a 29-megawatt solar steam plant at a Chevron oil field in Coalinga, Calif. The 100-acre project’s 7,000 mirrors will focus sunlight on a water-filled boiler that sits atop a 323-foot tower to produce hot, high-pressure steam. In a conventional solar power plant, the steam drives a turbine to generate electricity. In this case, the steam will be injected into oil wells to enhance production by heating thick petroleum so it flows more freely. Oil companies typically rely on steam generated by natural gas or other fossil fuels to maximize oil recovery in places like the oil patch in California’s Fresno and Kern counties, where the petroleum is heavy and gooey. That part of California also has some of the state’s strongest sunshine and several large solar power plants are planned for the region...NYTimes
