Chevron Testing Solar-Powered Oil Fields


In news that is both good and unsettling, Chevron has decided to add a slightly green tinge to their day-to-day dirty brown operations. How? By installing 7,700 solar panels generating about 740 kilowatts of electricity – to help power their oil refineries.

“By bringing together seven emerging solar technologies, Project Brightfield represents one of the most comprehensive solar energy tests of its kind and is an innovative approach to evaluating new technologies,” said Des King, president of Chevron Technology Ventures.

The power generated by the solar system at the site will be deployed to the local utility grid as well as to Chevron’s oil production complex at the company’s Kern River Field.

“Testing competing technologies side by side means that we can better understand their potential application at other Chevron facilities,” King said. Chevron Tech Ventures is the unit of Chevron U.S.A. Inc. that identifies, evaluates and demonstrates emerging technologies.

So is this an attempt to save money? Or is the oil giant actually trying to do it’s part?

“Chevron is mostly hedging its bets with these projects,” said Severin Borenstein, director of the Berkeley-based University of California Energy Institute. “The company sees it’s quite possible that the energy market might move away from fossil fuels.”

Chevron Using Solar Power To Pump Oil


Chevron will partner with BrightSource Energy to develop 29 megawatts of thermal power from the sun. The process uses mirrors to concentrate the solar rays onto a water tank, turning the water to steam. The steam can then be used to turn a turbine and produce electricity or 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.

Currently, oil companies like Chevron will usually burn natural gas to produce the steam necessary to get the oil going, and that method probably still be used at night and part of the day.
