Cornerstone Environmental and its BioCNG, LLC unit are opening natural gas vehicle fueling stations based on waste methane – and delivering the fuel at bargain prices.
Cornerstone Environmental is tapping landfill gas to make up to 250 gasoline gallon equivalents of ‘BioCNG’ in St Landry Parish, La. The facility opened March 26.
A landfill gas-based facility in St Landry Parish, La. opened today (March 26) and another, using methane from a local wastewater treatment plant, opened in Janesville, Wisc. in mid-February.
Each has a BioCNG 50 purification unit and can produce 250 gasoline gallon equivalents of CNG per day.
Cornerstone’s first installation, at the Rodefeld Landfill, in Dane County outside Madison, Wisc. (F&F, Sept. 20, 2010) opened at 100 GGE per day in late 2010 and is being expanded to 250, says VP Mike Michels. “We’re making biofuel at all three of these projects at under $1 a gallon,” he told F&F – with the cost of compression included.
BioCNG units employ Air Liquide membrane technology for carbon dioxide removal and a scavenger system dubbed SulfaTreat to remove hydrogen sulfide, Michels says.
Cornerstone Environmental is using methane from a wastewater treatment plant to make up to 250 gasoline gallon equivalents of ‘BioCNG’ in Janesville, Wisc. – which happens to be the hometown of facility fueling equipment supplier ANGI. The facility opened February 15.
The first vehicle was BioCNG-filled at the Rodefeld landfill in Wisconsin on March 18, 2011
The Janesville facility has compression and dispensing equipment from ANGI Energy Systems – which happens to have recently relocated there. In Louisiana, Cornerstone installed equipment from New Jersey’s Air & Gas Technologies.
