Brightmark RNG delivers first gas from its Larson Project in Florida

In California, Brightmark RNG Holdings LLC, a joint venture partnership between Chevron U.S.A. and Brightmark Fund Holdings LLC, announced the delivery of the first renewable natural gas (RNG) from its Larson Project in Okeechobee County, Florida. The Larson Project is comprised of four lagoon anaerobic digesters located at Larson Family Farms. This marks the joint venture’s inaugural RNG project in the state and builds on the joint venture’s extensive network of projects across the U.S. to produce dairy RNG for lower carbon intensity transportation fuel.

The Larson Project captures methane from cow manure through the process of anaerobic digestion and converts it to renewable natural gas. Methane is a potent greenhouse gas (GHG), the second most abundant GHG, and is responsible for roughly 17.3% of global emissions.

The produced RNG is used as transportation fuel and the remaining solids are transformed into organic fertilizer. In addition, recaptured water returns directly to the farm or site where the digester is located for reuse. The project delivers several environmental benefits, such as odor mitigation and air quality, soil stabilization, and nutrient control, improves the economics of dairy farming, and reduces the carbon intensity of agricultural practices.
