Biogas and Biomethane

Certain businesses produce organic waste that can be repurposed into a clean, renewable fuel source called biogas. When biogas is conditioned to pipeline-quality natural gas, it becomes biomethane. Here are some types of businesses that tend to have their own supplies of the waste needed to make biomethane:

  • Dairies
  • Food processing companies
  • Waste water treatment plants

Benefits of Biomethane

You can use biomethane to power equipment that uses natural gas or generate your own electricity on-site. This is a great way to save money and energy overall:

  • Lower emissions of unused "waste" methane
  • Reduce the need for conventional fossil fuel
  • Cut production and waste disposal costs

Unlike other sources of renewable energy—such as solar and wind—biomethane doesn’t need the sun to shine or the wind to blow. Waste material can be converted into deliverable, renewable energy 24/7!

Selling Biomethane on the Open Market

When biogas is conditioned into biomethane, it potentially sells at a higher price than natural gas. For example, Southern California Gas Company (SoCalGas®) had an average gas price of $3.89 per MMBTU in 2013, while biomethane could have been sold for in the range between $10 to $13 per MMBTU.

SoCalGas has an existing infrastructure of pipelines which can be used to transport biomethane almost anywhere. Are you interested in learning more about how to interconnect with SoCalGas' open access system?
