CalBio has over 100 dairy digester projects

Over 40 dairy digester projects are operational

Over 60 dairy digester projects are in development

When completed, this network of dairy biogas projects may be the largest system of its kind in the country.

CalBio develops three kinds of dairy digester projects:

  1. Biogas to a central facility where it is upgraded to nearly pure methane and injected into the utility pipeline, for use as Renewable Natural Gas (RNG) to fuel vehicles.
  2. Biogas to an on-dairy upgrading facility where it is upgraded to nearly pure methane and trucked offsite for use in vehicles.
  3. Biogas to a fuel cell or IC Engine to generate renewable electricity. It is then sold into the BioMAT or for use in electric vehicles, utilizing the LCFS program.
