Benefits of our biogas fuel cell systems


High efficiency
Runs directly off digester gas at high efficiency to produce renewable electricity and useful heat.


Remove contaminants
Our proprietary treatment system removes siloxanes and sulfur compounds to maximize useable biogas. 


Expedited permitting
Our platform's CARB certified emissions profile can expedite a project's air permitting process.


Experienced partner
We're a global leader in biogas fuel cell systems with two decades of proven biogas operations.

Biogas in. Renewable energy out.

Our systems are designed to thrive in applications that use anaerobic digester gas.
Heat from the fuel cells can be used for the anaerobic digestion process.

Expedited air permitting

Move swiftly through the air permitting process with our CARB certified distributed generation platforms.

Our carbonate fuel cells are certified to operate off natural gas and digester gas under the California Air Resources Board’s (CARB) standards, expediting the permitting process in certain clean air districts. Outside the state of California, the CARB 2007 certification independently validates the clean air profile of our plants.

Proven biogas experience

We are an established global leader in biogas fuel cell systems with two decades of successful operation.

In 2003, our first commercial shipment was a 250 kW system that operated on digester gas for a brewery in Japan. Our team has since deployed more than 20 MW of fuel cell systems operating on biogas at wastewater treatment facilities, agricultural facilities, and breweries.

Our global service organization provides 24/7 monitoring of all installed systems, and is able to dispatch service technicians rapidly to site. We stand behind our systems with long-term service agreements that cover all internal components.
