Renewable Energy - Dairy Farm

increase renewables in support of our business

We are increasing our use of renewables to power our operations. Efforts include renewable power purchase agreements for 65 megawatts of wind power in West Texas and 29 megawatts of solar power in Southern California. We work with partners like Novvi and San Francisco International Airport to deploy renewables to blend with our fuels and to develop renewable base oils for lubricants to reduce greenhouse gas emissions. We also collaborate with Pacific Ethanol, Waste Management and CalBio to provide renewable transport fuels. In addition, we evaluate potential feedstocks such as algae, woods, grasses and trees that can be used as cleaner sources of fuel in the future.

Chevron believes advanced biofuels can help meet the world’s future energy needs if they are scalable, sustainable and affordable for consumers. That is why Chevron is working to develop solutions that meet those criteria under an effective policy framework.

Chevron is actively evaluating options for biomass processing as part of our transportation fuels businesses, particularly in California. To date, our work, as well as that of others, to produce second-generation biofuels that are economical at scale without subsidies has not been successful. This included creating a joint venture with Weyerhaeuser, then the largest landowner in the United States, to try to commercialize cellulosic biofuels. We are exploring leveraging our current manufacturing facilities to produce biofuels along with our traditional petroleum products.

renewable diesel

Biofuels that complement conventional transportation fuels, such as renewable diesel, can play an important role in reducing the carbon intensity of transportation fuels while meeting the world’s growing energy needs. Renewable diesel, also known as biomass-based diesel, is a hydrocarbon diesel vehicle fuel produced from nonpetroleum renewable resources such as vegetable oils (soy, corn, canola, etc.), animal and poultry fat, used cooking oil, municipal solid waste, and wastewater sludges and oils. In 2017, Chevron began to distribute diesel fuel containing between 6 and 20 percent renewable diesel from some of our California fuel terminals.

Waste Management 

Already a leader in recycling, Waste Management (WM) now powers some of its trucks with gas emitted by its cargo. At Waste Management’s landfill gas-to-energy facilities, methane produced by decomposing trash is captured and used as an alternative fuel. More than half of the landfill gas collected at WM facilities goes to beneficial-use projects, making it North America’s leader in the space. Although much of WM’s landfill gas produces electricity, the Houston-based company is also a leader in converting landfill gas into natural gas fuels. Renewable natural gas (RNG) produced from processed landfill gas now fuels more than 33 percent of the company’s natural gas trucks. In 2018, Chevron and WM signed an agreement for Chevron to purchase gas produced by WM and ensure supply to WM’s trucks. “Chevron is a legacy supporter of our renewable natural gas program and recently increased that support by partnering with WM Renewable Energy to purchase the RNG produced at our American landfills,” said Randy Beck, senior director of renewable energy at WM. “This move furthers our commitment to each other, but more importantly, our commitment to sustainability initiatives.”

Chevron has applied and is evaluating emerging technologies that can be integrated into our businesses to reduce energy use, reduce carbon emissions and create new options for existing assets.

Chevron’s photovoltaic projects at Questa, New Mexico, and in the San Joaquin Valley, California, test and evaluate solar technologies. Project Brightfield, in Bakersfield, California, has evaluated seven photovoltaic technologies to determine the potential application of renewable power at other company-owned facilities. In 2019, Chevron signed a 20-year potential term power purchase agreement (PPA) in Southern California for 29 megawatt of solar energy to deliver to our Lost Hills oil field.

Our Casper Wind Farm, commissioned in 2009, has turned a former refinery site near Casper, Wyoming, into an 11-turbine, 16.5 megawatt–capacity wind farm that can produce enough electricity to power approximately 13,000 U.S. homes for a year. In May 2019, Chevron signed a 12-year green power purchase agreement to supply Chevron’s current West Texas Permian electricity load from a wind farm in West Texas. Through a separate transaction, Chevron has also purchased renewable energy credits (RECs) administered by the Electric Reliability Council of Texas to meet the state’s renewable energy program requirements.

In 2012, Chevron invested in a 49 megawatt–capacity joint venture geothermal facility in California that produces enough electricity to power approximately 40,000 U.S. homes for a year.
