Clean Methane Systems transforms complex biogas challenges into reliable, financeable energy assets through five core, value-engineered solutions:

CMS engineers a project from the ground up. We characterize your actual biogas, model the full process, and specify a system that integrates cleanly with your existing assets. You get conceptual design, sizing calculations, process flow and P&ID packages, and a defensible basis of design your engineer of record can build from.
CMS’ engineering and development services leverage more than 30 years of biogas project experience to highlight what will make your project predictable and successful. CMS will tailor the solutions to your specific needs. Do you want to maximize energy production, stay within a specific budget, or meet a tight delivery schedule? Those all drive important choices from technology to installation and operations.

Bad fuel can make a successful project challenging. Turbines, engines, fuel cells, linear generators, and RNG systems all share one vulnerability: contaminated gas. Hydrogen sulfide, siloxanes, VOCs, and moisture drive catalyst fouling, unplanned outages, and maintenance costs that seldom appear in the original project economics.
CMS builds automated conditioning systems, including IonPack, designed around your gas, your site, and your downstream equipment. Systems are engineered to meet guaranteed outlet specifications with lifecycle economics in mind—balancing performance, energy use, consumables, and maintenance rather than simply minimizing upfront cost.

Air quality rules tighten, feedstock changes, and a facility that was compliant at commissioning can drift into exposure without a single equipment failure. For a public agency, that exposure lands on the general manager and the board.
CMS can help identify where your operation is vulnerable, support air permit applications and agency correspondence, and can manage ongoing compliance as a service. We’ve supported facilities meeting grant conditions and regional air district requirements across regulatory regions and environments from Southern California to Western Australia.

Media exhausts. Gas composition shifts as feedstock changes. Instrumentation drifts. Performance degrades quietly, and the first clear signal is often damage to the generation equipment the system was installed to protect.
CMS provides field service, media change-outs, spare parts, operator training, performance evaluation and system optimization to keep systems matched to current conditions rather than original design assumptions. Our aftermarket support begins with systems we know firsthand: the systems CMS designed and built, including installations that have been operating for more than a decade.

Technically sound municipal biogas projects stall for one reason more than any other: no viable path to capital that fits a public agency’s timeline, balance sheet, debt capacity, and procurement rules.
CMS structures projects alongside financing and development partners who specialize in public infrastructure — including energy performance contracts, tax-exempt bonds, private financing, and project-level structures that can maximize your investment or even keep debt off the agency’s books. We work within the delivery model that fits your constraints, including design-build and design-build-own-operate-maintain.
