On-Site Oxygen for the Renewable Energy Industry — ON2 Systems

Oxygen Microaeration for Biogas H2S Desulfurization

Biogas and Renewable Natural Gas (RNG) producers use controlled oxygen injection into anaerobic digesters to remove corrosive hydrogen sulfide (H2S) biologically — feeding sulfur-oxidizing bacteria that convert H2S into harmless elemental sulfur without affecting methane production. ON2 containerized PSA oxygen plants deliver the 90–95% purity this process requires, generated on site from ambient air.

Containerized Oxygen Plants Built for Biogas Sites

ON2 ROCS container systems arrive as complete plug-and-play oxygen plants — generator, compressors, dryers, and filtration in one compact container — engineered for year-round outdoor operation from −30°C to +38°C. ON2 has designed and manufactured on-site oxygen generation systems since 1984, with systems operating today at renewable fuels and RNG facilities in California and at renewable energy projects in Canada.
