UNITED STATES BIOGAS MARKET FORECAST 2026-2034

More recent data indicate a gradual shift toward biomethane upgrading, driven by policies supporting renewable fuels and decarbonization in hard-to-electrify sectors. Globally, biomethane production remains a smaller fraction of total biogas output, estimated at around 10-15% in recent years based on regional trends and IEA projections.

Nevertheless, the pace of biogas upgrading to biomethane is accelerating in key markets, most notably in Europe, where biomethane production reached 4.9 billion cubic meters in 2023 and continues to represent a rising share of total biogas output. This growth is further supported in North America by robust policy incentives promoting renewable natural gas for transportation fuel and pipeline injection, driving significant expansions in production capacity.

Agricultural biogas sector expansion accelerated dramatically, growing 24% year-over-year as farm-based digesters surpassed landfill projects in new facility additions for the first time. The American Biogas Council data reveals 615 agricultural digesters now operate nationwide, with 93 new projects commissioned in 2024 compared to 24 landfill facilities.

Further, dairy operations account for 86% of farm-based systems, leveraging consistent manure production that generates 120-150 pounds daily per cow to create predictable biogas yields. Rural agricultural projects represented billions in capital investment, bringing economic development and renewable energy infrastructure to farming communities while addressing methane emissions from livestock operations.

The United States biogas market is segmented into source type, application, end-user, and technology. The technology segment is further categorized into fixed dome, floating drum, balloon, other plant concepts, wet vs dry digestion, and single vs multi-stage.

Other plant concepts encompass advanced anaerobic digestion configurations and gas upgrading technologies that optimize renewable natural gas production economics. This segment includes membrane separation, pressure swing adsorption, and water wash systems that remove carbon dioxide, nitrogen, and oxygen from raw biogas to achieve pipeline-quality biomethane specifications.

Technology selection depends on feedstock characteristics, particularly for landfill gas applications, where variable oxygen and nitrogen concentrations require sophisticated separation capabilities. Membrane-based upgrading systems offer modular designs with lower capital costs, making renewable natural gas projects more accessible for mid-scale developers.

Meanwhile, pressure swing adsorption delivers high methane recovery rates exceeding 99% purity, critical for transportation fuel applications and grid injection compliance. The segment benefits from continuous innovation around cost reduction and performance enhancement, as equipment suppliers develop next-generation systems that maximize methane recovery while minimizing upfront capital expenditure.

Advanced biogas desulfurization technologies address hydrogen sulfide removal challenges that affect equipment longevity and operational reliability across all biogas projects. Furthermore, modular plant designs enable phased capacity expansion, allowing project developers to scale production incrementally as feedstock availability increases and offtake agreements mature.

Some of the top players operating in the United States biogas market include Greenlane Renewables Inc, DVO Inc, etc.

Greenlane Renewables Inc operates as a specialized provider of biogas upgrading and desulfurization systems serving renewable natural gas developers worldwide. The company supplies three main biogas upgrading technologies, including water wash, pressure swing adsorption, and membrane separation systems, alongside proprietary biogas desulfurization equipment that removes hydrogen sulfide from raw biogas streams.

Headquartered in British Columbia, Canada, Greenlane maintains significant operations serving the United States market through system installations at landfills, wastewater treatment plants, dairy farms, and food waste facilities. Greenlane’s technology portfolio transforms biogas into pipeline-quality renewable natural gas suitable for grid injection or direct use as commercial vehicle fuel, supporting decarbonization objectives in natural gas distribution and heavy transportation sectors.

The firm recently filed patent applications for next-generation landfill gas upgrading technology architected to maximize methane recovery performance while reducing capital costs, making renewable natural gas projects more economically accessible for developers. Strategic focus areas include expanding aftermarket parts and service offerings that optimize existing facility performance, alongside developing licensing arrangements that generate recurring royalty revenues from international markets experiencing biomethane growth.
