Greenlane Biogas Contracted by Promus Energy to 
Supply Biogas Upgrading Solution for Dairy Farm

Burnaby, BC – Greenlane Biogas has signed a contract with Promus Energy, a project development company focusing on renewable and sustainable technologies, to provide an integrated biogas upgrading solution for a dairy farm located in Yakima County, Washington. Included in the solution is the supply of a Totara+ biogas upgrading unit and additional process equipment to deliver pipeline quality renewable natural gas (RNG).

With the capacity to upgrade biogas at a rate of 1,500 SCFM, the Totara+ system will convert organic waste from a herd of 10,500 dairy cows into approximately 8,300 diesel gallon equivalents per day of pipeline grade RNG. Using an environmentally friendly process that removes impurities with water only and no chemicals, the RNG produced by the high efficiency Totara+ upgrading system has a purity > 97% methane. RNG produced at the farm will be sold to nearby transportation fleets and injected into the Williams Northwest Pipeline through a new 3.7 mile pipeline equipped with shared access points that will allow other dairies in the area to easily connect to the pipeline grid if they become RNG producers in the future.

“We see great potential to apply this technology and offtake model for hundreds of dairies across the country,” said Gary Coppedge, CEO for Promus Energy. “Greenlane has proven technology and expertise behind its solution, having supplied biogas upgrading systems for anaerobic digester projects such as Fair Oaks Dairy in Indiana. And with the success we have had carrying out contracts with RNG buyers, we have verified this model can work.”

Brent Jaklin, Managing Director for Greenlane Biogas North America said: “We are excited about being selected by Promus to work with them on this project which we believe can revolutionize the agricultural industry. This project further solidifies our leadership position in the biogas upgrading space and we are optimistic about the prospect of future projects with Promus in Yakima County and beyond.” 

Yakima County is one of the most active dairy centers in the United States and concerns about the dairies impacting water and air quality have farmers looking for ways to improve their waste management practices. In 2006, an anaerobic digester was installed at the dairy farm to convert manure from its herd to methane gas which was used for power generation. As production declined over the years, the farm partnered with Promus Energy to better utilize its organic waste by converting it into revenue generating products.
