Chevron will tap sunlight to help it get more oil out of the ground in California. The company will partner with BrightSource Energy—a solar start-up that Chevron helps fund—to develop 29 megawatts of thermal power from the sun's rays.
The idea is simple (and ancient): use mirrors to concentrate the sun's rays onto a water tank, turning said water to steam. The steam can then be used to turn a turbine and produce electricity or, in this case, pumped down a well to loosen heavy oils.
The plant slated for the Coalinga Oil Field near Fresno will employ at least 3,000 mirrors to concentrate light on a more than 300-foot tower with water inside. Chevron hopes it will be fully operational by the end of next year. "The only problem we have is when it's cloudy," said Sergio Hoyos, a business developer at Chevron Technology Ventures, at the city council meeting last week where the plan was unveiled, according to Reuters.
