February 6 (Renewables Now) - US waste and energy developer Brightmark Energy LLC has signed an agreement with two dairy companies in South Dakota for the supply of cow manure to advance the development of the Athena renewable natural gas (RNG) project.

Thanks to the partnership with the two businesses, Boadwine Farms Inc and Mooody County Dairy LP, Brightmark will be able to capture methane produced by a close to 12,000-head cow and heifer herd and convert it to pipeline-quality RNG.

The waste and energy developer has said it plans to build anaerobic digesters at three dairy farms in Minnehaha County, which collectively leave behind a total of 55.6 million gallons of manure each year.

This amount of manure is expected to result in the estimated annual production of 217,000 MMBtu of RNG. According to Brightmark, this is equal to the amount of gas needed to drive 2,492 vehicles for a full year.

Besides developing the Athena RNG project, Brigthmark will also own and operate it once it is finalised. The resulting gas will be injected into the local interstate pipeline system for statewide use.
