U.S. Gain, a leader in the development, procurement and distribution of renewable natural gas (RNG), proudly announces that after only eight months their digester at S&S Jerseyland Dairy in Sturgeon Bay, Wis., is now transforming animal waste to clean, low carbon fuel for the transportation market.
“We’re pleased to add this project to our RNG development portfolio and in such a short amount of time,” said Mike Koel, president of U.S. Gain. “As organizations continue the shift from fossil-based products to renewables, the demand for RNG as an alternative fuel and thermal energy continues to climb. We’re excited to be involved in so many dairy-based RNG development projects because of the multitude of benefits brought to rural and urban communities across the nation.”
The anaerobic digester at S&S Jerseyland Dairy has been operational since 2011, initially converting waste from the farm’s 4,000 herd of Jersey cows to renewable power. U.S. Gain purchased the farm’s digester in September of 2019 and made the upgrades needed for fuel production. Gas collected at the facility is taken through a complex processing system that results in RNG comprised of 99.5 per cent methane. The facility recently obtained project certification from the California Air Resources Board, Oregon Department of Environmental Quality and the Environmental Protection Agency. Typically, projects like these take 12 to 18 months to bring online. “We are proud to announce its completion much sooner than anticipated,” Koel said.
A key partner to U.S. Gain throughout the project was Nacelle Solutions, a leader in developing gas clean-up equipment specifically designed for the RNG industry. “We are pleased to announce this project maximizes methane recovery and speed to market – two key goals initially outlined by U.S. Gain and Nacelle,” said Nacelle’s co-founder Gov Graney.
“Methane recovery was maximized through additional processing capabilities in the upgrade portion of the plant, specifically a third stage membrane process. The more plants we do, the more efficient and streamlined we become, enabling speed to market with reliable results,” explained Graney.
RNG produced at S&S Jerseyland Dairy is transported to U.S. Gain’s new decant facility, then injected into the pipeline and transmitted to organizations throughout the nation seeking low carbon solutions to satisfy their sustainability targets.
