Dane County, Wis., officials unveiled a new BioCNG filling station located at a county landfill on August 23. BioCNG’s biogas conditioning system economically produces biogas-based fuel to power compressed natural gas (CNG) vehicles at the Rodefeld Landfill, in Dane County.

The fueling station will more than double the CNG generation of the county’s existing facilities at the landfill. The facilities will generate 250 gasoline gallon equivalents (GGEs) of CNG per day. The new station will also increase fuel storage more than six-fold. And, the landfill’s BioCNG vehicle fueling station operates in conjunction with an existing landfill gas electrical generation system.

The BioCNG system fuels Dane County parks and public works trucks. The station is an important component of Dane County Executive Joe Parisi's effort to expand the County’s use of CNG over the next 10 years.

The BioCNG generated at the landfill costs the County the gasoline equivalent of $1.25 per gallon to fill up its fleet. “The last time gas was a little over a buck a gallon was 30 years ago,” Parisi said.

The roughly $500,000 station was funded in part by a Wisconsin State Energy Office (SEO) grant totaling $150,000. An additional $28,800 was recently awarded to the County from the SEO to cover half the cost of five new CNG vehicles for the county, bringing the total CNG fleet to 30.

To further increase CNG use in the fleet, the county ordered four snow plows that would run on CNG generated at the County landfill. Dane County would be the first to use this innovative equipment on large snow plows that could hit the roads as soon as this winter, the release stated.
