BioCNG to design biogas conditioning system, pipeline

By BioCNG LLC | July 28, 2014

BioCNG LLC has announced that it has been selected to design and build a BioCNG biogas conditioning system and gas pipeline for the Persigo wastewater treatment plant, which is jointly owned by the City of Grand Junction and Mesa County, Colorado. The BioCNG system will produce about 500 gallons of gasoline equivalent per day from the WWTP digester gas, which will be piped about 6 miles to Grand Junction's existing compressed natural gas (CNG) fueling station. BioCNG will be supported locally by River City Consultants and other local vendors and sub-contractors.

The BioCNG will be used as fuel for a fleet of buses owned by Grand Valley Transit and fueled at the City of Grand Junction facility, as well as City refuse trucks, street sweepers, and general utility pickups. The City of Grand Junction and GVT continue to purchase additional CNG vehicles to increase the overall CNG fleet.

"We are excited about being able to produce our own fuel so we can have a better handle on what our fuel costs will be in the future," said Rich Englehart, city manager of Grand Junction. "This project will help control the city potential fuel price escalation."

BioCNG will engineer the system, obtain all necessary permits, manage the construction, and commission and start up the system. Future work may include investigation of an option to modify BioCNG system tail gas for use in the WWTP digester boiler, thereby saving on treatment plant operating costs.

Matt Davies, president of BioCNG LLC, said, "I am very excited to have been selected by the City of Grand Junction and Mesa County to help them expand the use of CNG for their fleet." There are currently five other BioCNG systems in operation around the United States, which vary from 250 to 500 gallons of gasoline equivalent (GGE) of CNG per day from about 50-100 standard cubic feet per minute (scfm) of biogas.
