bp and Aria Energy to capture methane at California dairy farms as part of RNG project

In Texas, bp and Aria Energy are working together on a project to capture methane from waste at three California dairy farms and process it into renewable natural gas, which will then be supplied as fuel for the US transportation sector.

Digesters will be installed at three dairy farms in California’s Central Valley, producing biogas from farm waste rather than allowing it to decompose and release methane into the atmosphere.

RNG-fueled vehicles are estimated to result in up to 95 percent lower emissions than those fueled by gasoline or diesel on a lifecycle basis, according to a US Department of Energy study.

The project, called RNG Moovers, combines the expertise of three companies:

• Aria Energy providing expertise in capturing biogas released from organic waste and refining it to remove contaminants and increasing its heat content, resulting in RNG.
• Aligned Digesters contributing proven experience constructing and operating digesters along with decades-long relationships with nationwide dairy owners.
• bp delivering the RNG to the transportation sector through a 20-year offtake agreement executed by its low carbon trading business.
