The Kirkman Project

About the project

The Kirkman renewable natural gas (RNG) project is in rural Shelby County, Iowa. The manure from this farm will produce renewable natural gas each year. After the anaerobic digestion project is operational, the biogas generated by this manure will be captured, cleaned, and converted into RNG, which can be used as transportation fuel, industrial heating, and a host of other applications. Developed in the third tranche of RNG projects from Brightmark and Chevron’s joint venture, Kirkman is expected to begin producing RNG in 2022.

“At Kirkman farms, we strive to do right by our employees, animals, customers, neighbors, environment, and our overall community. Brightmark has been a great partner working together with us to become a carbon-neutral dairy farm by converting methane from cow manure into a renewable natural gas in an environmentally sustainable and continuous process.”

– Matt Van Baale, Owner/Partner Kirkman Farms


In October 2020, Brightmark LLC and Chevron U.S.A. Inc. originally announced the formation of the Brightmark RNG Holdings LLC joint venture to own projects across the United States to produce and market dairy biomethane, a renewable natural gas. Equity investments by each company in the new venture fund construction of infrastructure and commercial operation of dairy biomethane projects in multiple states. Chevron purchases RNG produced from these projects and markets the volumes for use in vehicles operating on compressed natural gas.
