By Reuters Staff Slideshow ( 3 images ) (Reuters) - Chevron Corp is partnering with Microsoft Corp, oilfield services firm Schlumberger NV and privately held Clean Energy Systems to build a carbon capture plant in California, as the U.S. oil major expands investments in renewable technology. Fossil fuel companies have faced increased pressure in recent years to reduce emissions, spend more on low-carbon energy and disclose the impact their production has on climate change. Chevron said on Thursday the plant, located in the city of Mendota, will convert agricultural biomass to electricity, and almost all the carbon captured in the conversion of agricultural waste would be stored underground.
