Projects

CalBio has over 60 California Dairy Digester projects operational or in development.

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

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 in partnership with Chevron and others.
  2. Biogas to an on dairy upgrading facility where it is upgraded to nearly pure methane and onloaded to a tube trailer and delivered offsite for use as Renewable Natural Gas (RNG) to fuel vehicles.
  3. Biogas to a fuel cell or IC Engine to generate renewable electricity utilizing the BioMAT feed in tariff or relationships with electric vehicle fleet operators or auto manufacturers.

Digester Projects

Typical large electric generation projects

Old River

The Old River project is a 2 MW, two cell, double-lined lagoon digester and is currently the largest in the state. It has been operating since 2013. Electricity from this project will be used to power electric vehicles.

West-Star North

Recipient of funding from CDFA and CEC, this two cell, double-lined, covered lagoon digester produces 1 MW of electricity. It is also an anchor for the Buttonwillow cluster which is currently in development.

Lakeview

Recipient of funding from CDFA and CEC, this double-lined, covered lagoon digester produces 1 MW of electricity.

CE&S

Recipient of funding from the California Department of Food and Agriculture (CDFA) and the California Energy Commission (CEC), this double-lined, covered lagoon digester generates 1 MW of electricity. Waste engine heat is used to cool milk and produce hot water.

Typical Large Fuel Cell Electric Fuel Projects

Stockdale

CalBio’s first project, this 600kW facility is located outside of Bakersfield. It was one of the first double-lined covered lagoon digester’s in the state. This project is being upgraded to accommodate a Bloom fuel cell generator.

Bar 20 Dairy Biogas and Southpoint Biogas

These two fuel cell projects are in development.
