Renewable Natural Gas Success Stories

Learn how biogas becomes renewable natural gas (RNG) and read about companies who are already doing this.

Where do biogas and biomethane come from? Here’s an overview of the process for converting biogas into renewable natural gas:

  1. Waste products, such as wastewater, food waste and manure are processed in a biodigester.
  2. The biodigester breaks down the organic material through an anaerobic process, creating biogas — a mixture of methane, carbon dioxide (CO2), and other gas constituents.
  3. Biogas is then conditioned and upgraded to remove the COand other gas constituents, leaving a high concentration of methane. This produces renewable natural gas, or RNG, which can be used interchangeably with traditional natural gas. Learn more about pipeline gas quality requirements here.
  4. RNG can be used where it is produced for purposes such as generating electricity or fueling vehicles, or it can be injected into the utility pipeline and transported to an end user.
