Biomethane Market Set to Reach USD 8.96 Billion by 2032 as Renewable Gas Demand Accelerates

The Biomethane Market is entering a period of sustained expansion as governments, utilities, industries, and waste-management companies accelerate the transition toward low-carbon energy. According to Maximize Market Research, the Biomethane Market was valued at USD 5.93 Billion in 2025 and is expected to grow at a CAGR of 6.08% from 2026 to 2032, reaching nearly USD 8.96 Billion by 2032.

Market Estimation, Growth Drivers and Opportunities

The market is driven by the global push to reduce greenhouse-gas emissions and replace fossil fuels across transportation, industry, heating, and power generation. Biomethane can use existing gas infrastructure and is produced from feedstocks such as municipal waste, animal manure, wastewater sludge, and other organic materials. Advances in anaerobic digestion, gas purification, membrane separation, and upgrading technologies are improving production efficiency and helping lower operating costs.

Decentralized biomethane plants provide opportunities for rural economic development, local energy generation, waste treatment, and improved energy resilience. Converting food waste, agricultural residues, sewage, and manure into renewable gas creates additional value while reducing waste-related emissions. High upfront investment and reliable feedstock availability remain important considerations for developers.

U.S. Market Trends and Investment

The United States biomethane market showed notable project activity during 2025, particularly around landfill gas, agricultural waste, and renewable natural gas infrastructure. Air Liquide expanded biomethane capacity through facilities in Pennsylvania and Michigan that convert dairy manure into biogas and upgrade it into renewable natural gas using membrane technology, with combined production capacity of about 74 GWh annually. In May 2025, OPAL Fuels and a Republic Services affiliate announced a joint venture for an RNG facility at the Charlotte Motor Speedway Landfill in North Carolina, designed for approximately 1.4 million MMBtu of annual production.

Leading Market Segment

By feedstock, Municipal Waste held the largest share of the Biomethane Market in 2025. Municipal organic waste provides a consistent source of biodegradable material, including food scraps and garden waste, while biomethane production simultaneously supports waste diversion and renewable-energy generation.

By production method, Anaerobic Digestion dominated the market in 2025 because of its established technology, scalability, ability to process wet organic feedstocks, and mature commercial ecosystem. The process converts organic material into biogas, which can then be upgraded into biomethane.

Competitive Analysis

The competitive landscape includes major energy, gas, waste-to-energy, and biogas technology companies. Among the prominent companies identified in the Maximize Market Research report are Air Liquide, ENGIE, Nature Energy Biogass A/S, Teréga Solutions, and Waga Energy. These companies are strengthening the market through production capacity expansion, renewable-gas contracts, infrastructure development, and upgrading technologies.

Air Liquide is expanding biomethane production using proprietary membrane separation technology and manure-based feedstocks in the United States. ENGIE is developing renewable-gas capacity and has targeted substantial biomethane production expansion through 2030; in 2025, its innovation activities also included projects related to biomethane production units. Nature Energy continues to focus on large-scale biogas and biomethane production from organic waste and agricultural feedstocks. Teréga supports biomethane integration through gas infrastructure and injection stations, while continuing research and innovation activities around gas networks. Waga Energy is advancing landfill-gas-to-biomethane technology through its Wagabox systems; its 2025 investments supported additional unit construction and expansion of its production portfolio.

Regional Analysis: Germany, UK and France

Germany remains a major biomethane and biogas market, supported by established production infrastructure and renewable-energy policies. In 2025, Germany strengthened support for existing biogas facilities through measures increasing biomass tender volumes and flexibility incentives, encouraging investment in flexible renewable-energy generation.

The UK is expanding biomethane deployment as part of its low-carbon gas strategy. The Green Gas Support Scheme supports new biomethane production through anaerobic digestion and grid injection, while government energy policy recognizes biomethane as a domestically produced low-carbon gas that can reduce dependence on conventional natural gas and support hard-to-abate sectors.

European Commission approval of a €1.5 billion French state-aid scheme supports sustainable biomethane production in France. The country is also moving toward a biomethane blending mandate for grid injection, creating additional demand and improving the investment environment.

Key Players

Key companies covered in the Biomethane Market include Air Liquide, ENGIE, Nature Energy Biogass A/S, Teréga Solutions, Waga Energy, TotalEnergies, Archea Energy, EnviTec Biogas AG, Future Biogas, Gaz Métro (Énergir), Greenlane Renewables, VERBIO, Landwärme, PlanET Biogas, Schmack Biogas, BioConstruct, Scandinavian Biogas, BTS Biogas, Agraferm Technologies, Agrinz Technologies, and Puregas Solutions.

Why This Market Matters Now

Biomethane matters now because it connects three major priorities: renewable energy, waste management, and emissions reduction. Unlike energy sources requiring entirely new distribution systems, biomethane can be injected into existing gas networks and used in applications already dependent on gas. Europe’s target of 35 billion cubic metres of annual biomethane production by 2030 and continued investment in upgrading and grid infrastructure highlight the market’s strategic importance. As governments seek energy security, industries pursue lower-carbon operations, and cities look for productive uses for organic waste, biomethane is becoming an increasingly important component of the global energy transition.
