Three renewable natural gas projects — in Hartford and Greenville, on the west side of the state, and Morenci, near the Ohio border — have broken ground and are expected to be completed next year by San Francisco-based Brightmark.
“Michigan has been a great partner and we are excited to further expand our renewable natural gas project footprint here and break ground on these lifecycle carbon negative projects,” says Bob Powell, founder and CEO of Brightmark.
“Transitioning to a lower carbon energy economy creates significant opportunities for Michigan to put people to work in good-paying jobs in industries that are key to addressing climate change. We are proud to be a leader in supporting more sustainable farming practices, and these new RNG projects have the potential to deliver great financial and environmental benefits to the farmers and communities that we partner with.”
In October 2020, Brightmark and Chevron U.S.A. Inc. formed the Brightmark RNG Holdings LLC joint venture to own projects across the United States to produce and market dairy biomethane, a renewable natural gas.
The Red Arrow RNG project in Hartford will use anaerobic digestion systems to convert 200,000 gallons of manure per day from 5,750 dairy cows into about 128,000 MMBtu (or thousand British thermal units) of RNG each year.
“One of my favorite parts of the job is implementing new technologies here on the farm that enable us to run more efficiently and improve the sustainability of our operations,” says Rudolf de Jong, president of Red Arrow Dairy.
The SunRyz RNG project in Morenci will convert 133,000 gallons of manure per day from 3,250 dairy cows into about 76,000 MMBtu of RNG each year – enough fuel to enable a heavy-duty truck to circle the equator 77 times. The RNG generated at SunRyz will be injected into the nearby Rover pipeline.
The Meadow Rock Renewable Natural Gas project in Greenville will convert 75,000 gallons of manure per day from 3,020 dairy cows into nearly 67,000 MMBtu of RNG each year. The RNG produced at Meadow Rock will be injected into the ANR Pipeline.
“We’re proud to be partnering with Brightmark on anaerobic digestion projects at two of our Michigan dairy farms,” says Jordan den Dulk, manager of Meadow Rock Dairy. “The Brightmark team has been responsive to our needs from day one, and we’re looking forward to the sustainability and financial benefits of these projects.”
