The Black Soil Project

The Black Soil renewable natural gas (RNG) project in Granville, Iowa, includes the construction of a new anaerobic digester on the Black Soil Dairy Farm. The manure from this farm will produce renewable natural gas each year. After the project is complete, 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. Black Soil is part of the third tranche of projects developed under the Brightmark RNG Holdings LLC joint venture with Chevron U.S.A. Inc.

“This project is a win-win for our farm—we’re looking forward to the new value stream we’ll get from our manure, and Brightmark has been a solid partner from day one.”

– Nate Zuiderveen, Owner of Black Soil Farm

Project Benefits

GHG Reductions

The Black Soil project is anticipated to prevent greenhouse gas emissions each year.

Resource Recovery

Recovering and processing manure from the farms will prevent excess emissions from escaping into the local air and water.

Waste To New Products

The facility will generate renewable natural gas each year.

Partners

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 used in vehicles operating on compressed natural gas.
