Chevron Logo The human energy company

Chevron U.S.A. Inc.

Chevron partnered with CalBio and California dairy farmers to produce and market dairy biomethane, a renewable natural gas (RNG). The company is funding infrastructure for dairy biomethane projects in California’s San Joaquin Valley and providing marketing services to bring RNG into the California fuels market. Chevron is working to produce and market dairy biomethane as a cost-effective solution to comply with California’s Low Carbon Fuel Standard.


4Creeks and CalBio have been partners in the dairy digester industry for multiple years, providing Engineering Design Services and permitting for digesters built across the Central Valley. 4Creeks works with dairymen to understand their needs and assess the value of a digester. The 4Creeks team offers start to finish services, beginning with conceptual site plans, assistance with grant preparation and permitting and works closely with the Water Board, Air District, and Counties to ensure the permitting process goes smoothly. Throughout the design process, 4Creeks works with the farmer to ensure dairy operations benefit from the design of the digester, and that it works seamlessly with current and future dairy management needs.

4CG Construction

4CG Construction is a construction management company and the sister company to 4Creeks. 4CG oversees building the dairy digester and the integration, per the engineering plans, of the digester into the dairy’s manure management system. 4CG works with leading manufacturers and local contractors including earth movers, cement and electrical trades. A long-standing partner to 4CG and CalBio is Environmental Fabrics Inc (EFI).

Bloom Energy, Inc. logo

Bloom Energy, Inc.

Bloom Energy has formed a joint technology collaboration with CalBio to deploy Bloom fuel cell “Energy Servers” for the efficient and clean conversion of dairy waste into renewable electricity without combustion. CalBio’s dairy digester technology, combined with Bloom Energy’s solid oxide fuel cell technology, delivers an end-to-end solution for the capture of methane and generation of renewable electricity to power electric vehicles (EVs) throughout California.  Integrating Calbio’s and Bloom’s proven technologies creates the world’s first commercial solution to directly generate electricity from dairy waste without combustion, to power EVs.

Land O'Lakes, Inc. logo

Land O’Lakes, Inc.

Land O’Lakes launched a first-of-its-kind collaboration with CalBio to support the financing, installation and management of on-farm methane digesters to generate renewable compressed natural gas (“R-CNG”) fuel in California. Land O’Lakes promotes CalBio’s innovative farmer-led model for “barn to biogas” to help shape solutions to agricultural methane emissions reduction and unlock new revenue streams for dairy farmers.  As one of the nation’s largest agricultural cooperatives, Land O’Lakes is uniquely positioned to tap into the potential power of California dairy farmers to generate renewable energy from farm waste.

PCL Industrial Services, Inc.

PCL Industrial Services, Inc.

PCL is CalBio’s engineering procurement and construction partner for deploying biogas processing equipment and gathering lines throughout the San Joaquin Valley.  PCL’s extended group of construction companies with an annual construction volume of more than $8 billion, make PCL one of the largest contracting organizations in North America.  PCL was selected by CalBio based on its: capabilities, experience, track record, local California team, substantial Bakersfield manufacturing and fabrication facilities, strong balance sheet and its financial capability to successfully implement large complex gas processing construction projects in California’s San Joaquin Valley.

Government Agencies/Funding Partners

California Air Resources Board logo

California Air Resources Board (CARB)

The California Air Resources Board (CARB) partners with air districts, community groups and members, environmental organizations, and regulated industries across California to reduce exposure in communities most impacted by air pollution. According to CARB’s statewide GHG inventory, dairy and livestock are responsible for over half of California’s methane emissions. It is recognized that improved dairy manure management offers significant, near-term potential to achieve reductions in the State’s methane emissions. CalBio works closely with CARB to identify barriers to dairy emissions reduction projects and increase the utilization of methane, which would otherwise be emitted into the atmosphere, to create renewable biogas.

California Department of Food and Agriculture (CDFA) logo

California Department of Food and Agriculture (CDFA)

CDFA has been a significant supporter of CalBio and its dairy farmer partners.  CDFA grants provide important funding for a small but significant portion of a dairy farmer’s digester project.  The CDFA grant funds help lower project risks and are substantially leveraged with other partner, CalBio and bank capital.  CDFA grant funding is provided through California’s cap and trade program.

The California Energy Commission logo

California Energy Commission (CEC)

The California Energy Commission (CEC) offers grants that advance the state’s transition to clean energy and transportation through innovation, efficiency, and the development and deployment of advanced technologies.  CalBio’s implementations of innovative clean energy and transportation technology in the dairy sector have been greatly assisted by the CEC’s support over the years.

California Public Utilities Commission (CPUC) logo

California Public Utilities Commission (CPUC)

The California Public Utilities Commission (CPUC) awarded CalBio and its dairy farm partners three of the six Dairy Pilot Project awards.  These three awards fund a portion of CalBio’s dairy digester clusters in North Visalia, South Tulare and Buttonwillow areas of the San Joaquin Valley.  Over thirty large dairies will soon be contributing their biogas into systems which will upgrade it to renewable natural gas for vehicle fuel use in California.

Natural Resources Conservation Service (NRCS)

The Natural Resources Conservation Service (NRCS) of the USDA helps protect natural resources by working with farmers and ranchers to assist them in boosting agricultural productivity. NRCS is on a mission to “deliver conservation solutions so agricultural producers can protect natural resources and feed a growing world.” In its projects CalBio and the dairy partner with NRCS in reducing methane emissions while also benefiting the farm and the herd and protecting our natural resources.
