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. And with the success we have had carrying out contracts with RNG buyers, we have verified this model can work.”
