RNG offloading station to receive first load of biogas at Dane County

May 12, 2020. The renewable natural gas (RNG) offloading station at Dane County, Wisconsin’s landfill is scheduled to receive its first load of biogas. The biogas will be brought from a Wisconsin digester that collects the methane from manure which reduces greenhouse gas emissions and harmful runoff to lakes and streams. The digester’s biogas will be injected through the county’s equipment into the interstate transmission pipeline so it can be used as renewable fuel, powering fleets of RNG vehicles locally and across the U.S.

“We are thrilled to reach this milestone at the Dane County landfill,” said County Executive Joe Parisi. “It took a lot of hard work and dedication from our staff and industry partners to see this through to the end. It is exciting to see this effort shape the industry. We look forward to the positive impact it will have on our clean lakes efforts, as well as the local economy.”

Agriculture accounts for 30% of the total emissions of methane, a naturally occurring greenhouse gas (GHG), which is 25 times more potent to the atmosphere than carbon dioxide. When used as renewable vehicle fuel, every trailer that comes through Dane County’s offloading station will reduce GHG emissions equivalent to that of burning 24,000 pounds of coal.

The RNG offloading station, the first-of-its-kind in the nation, was part of a larger project to process the county’s landfill biogas for pipeline injection. Traditionally, each biogas producer is required to make a physical connection to the pipeline which can cost millions of dollars for piping installation, equipment, and connection fees. Since the county was already making that connection for the landfill biogas project, an offloading station was added for other biogas producers to use. This revolutionary project reduces the barriers for biogas producers to gain access to the pipeline, renewable energy markets, and the U.S. Environmental Protection Agency’s (EPA) and state issued renewable fuel credits.
