Delivering Value Across Biogas Feedstocks
“We are excited to partner with Mainspring and continue to demonstrate production of renewable electricity using a new and innovative technology that has the potential to increase efficiency of electricity production and reduce air emissions.”

Director of Integrated Waste Management (former)
Yolo County, California
Significantly Lighter Cleanup Requirements When Compared With Fuel Cells
- Mainspring’s biogas input composition requirements are much lighter than those of RNG in all steps of the cleanup process
- As a result, depending on the project size, the cost of biogas cleanup can be up to 70% lower with Mainspring than with a typical fuel cell project.
Dispatchability Captures Value Across Seasons
The full dispatchability of Mainspring's technology allows the products to ramp up and down with biogas production levels. In contrast to baseload-only fuel cell technology, this maximizes production and revenue potential and reduces the need for flaring throughout the year.
Incentive Eligibility
Mainspring Linear Generators are ITC eligible
The Inflation Reduction Act of 2022 specifies linear generators as eligible for the 30% investment tax credit within the definition of fuel cells in Section 48 of the Federal Tax Code.
Self-Generation Incentive Program (SGIP)
California customers using biogas to power onsite operations through linear generators may qualify for state funding from the Self-Generation Incentive Program (SGIP).
