Dane County, Wisconsin – BioCNG Vehicle Fuel Project at Rodefeld Landfill

Award-winning project fuels county vehicles with cheaper, cleaner-burning compressed natural gas produced from landfill gas

 

Prev Prev

Cornerstone is implementing a landfill gas (LFG) to vehicle fuel project at the Dane County Rodefeld Landfill, in Madison, Wisconsin. The project is focused on producing a small but economically viable quantity of biogas based fuel using a new patent pending BioCNG™ fuel conditioning system to power compressed natural gas (CNG) vehicles. Valuable information is being gained regarding the small scale production and utilization of biogas as a vehicle fuel.

The county and partners were recently awarded the coveted Environmental Protection Agency’s 2011 Project of the Year Award for the project as part of EPA’s Landfill Methane Outreach Program (LMOP).

The project is being implemented in collaboration with partners and supporters from both the private and public sectors, including Dane County, Cornerstone Environmental Group, Alliant Energy, Madison Area Technical College, Unison Solutions, and ANGI Energy Systems. Together they implemented the BioCNG system, enabling the county to fuel converted parks and public works trucks with CNG fuel that costs a mere 20 cents per gallon of gasoline equivalents.

The Rodefeld Landfill BioCNG system was designed and fabricated in 2010 and was installed along with a CNG fueling station in December 2010. Fuel testing and use of the conditioned LFG as vehicle fuel has proceeded successfully.

Key Project Activities
