Biomethane Market Size & Share Analysis - Growth Trends and Forecast (2027 - 2032)

Market Trends and Insights

Decarbonization Of Hard-To-Electrify Sectors

High-temperature industrial heat, maritime transport, and chemical processing have limited direct electrification options. These users can use biomethane as a substitute for fossil gas without replacing all existing gas assets. This makes the global biomethane market relevant to buyers seeking lower operational emissions while retaining familiar fuel systems. Shipping, steel, cement, and heavy chemicals still need scalable decarbonization routes, according to the World Economic Forum’s 2025 assessment. Food and beverage manufacturers and pharmaceutical producers are increasingly specifying renewable gas in supply contracts as their 2030 commitments approach. IEA Bioenergy documented biogas adoption across food and beverage and paper operations in Austria, Denmark, France, and Sweden, where biodegradable by-products can support co-located supply.^[1]

Renewable Gas And Energy-Security Policies

European policy combines support for gas injection, transport use, and maritime decarbonization. The global biomethane market benefits where policy creates a durable demand signal instead of a short-lived capital incentive. France had 803 grid-injecting installations with 15.5 TWh of annual capacity in 2025, and its capacity was expected to reach 44 TWh by 2030 under the third multi-annual energy plan. France’s production certificates became operational in January 2026 and require gas suppliers to meet renewable-gas quotas. The European Commission reaffirmed biomethane’s role in its May 2025 REPowerEU update, supporting policy amendments in Poland, Spain, and Italy.^[2] The strength of these measures will depend on national implementation, especially permitting and access to distribution networks.

Waste-To-Energy And Methane-Abatement Mandates

Waste diversion rules and agricultural methane programs convert organic residuals into more secure inputs for producers. This expands the global biomethane market by linking waste management obligations with fuel production. The American Biogas Council reported USD 2.1 billion of investment in new United States biogas systems in 2025. Investment in food waste systems more than doubled to USD 325 million, while food waste capture capacity rose 18% to 28 bcf per year. Industrial processors and retailers can reduce landfill costs while meeting internal waste targets through long-term feedstock agreements. Agricultural renewable natural gas facilities in the United States rose from 90 in 2020 to 414 at the end of 2025, supported by Renewable Fuel Standard pathways and United States Department of Agriculture programs.

Transport Fuel Credit And Certification Stacking

Multiple revenue streams can improve project economics for transport-focused biomethane plants. Renewable fuel credits, greenhouse gas quota payments, and carbon instruments are most material where certification systems are established. In the United States, 68 of 70 biogas projects commissioned in 2025 were designed to upgrade output to renewable natural gas. Those projects contributed to a 24% increase in renewable natural gas production to 225.6 million MMBtu. FuelEU Maritime and EU emissions trading requirements are also encouraging bio-LNG use in shipping. Gasum’s biomethane share of its maritime sales rose from 0.8% in 2024 to 12.3% in 2025, showing the role of compliance-based demand in the global biomethane market.

High Upfront Capital And Feedstock Logistics Costs

Capital costs are a material barrier where projects are small, remote, or dependent on specialized upgrading and liquefaction equipment. The global biomethane market faces a scale challenge because many agricultural feedstocks are dispersed across rural locations. France’s energy regulator reported anaerobic digestion biomethane costs of EUR 54/MWh at plants above 1,200 Nm³/h and EUR 130/MWh at smaller plants. Grid injection added EUR 5/MWh, while liquefaction added EUR 20-25/MWh for bio-LNG routes. Long transport distances can raise feedstock costs and reduce the lifecycle emissions benefit of centralized digestion. Financing is more difficult in Brazil and Vietnam, where long-term offtake structures are less established.

Limited Sustainable Feedstock Accessibility

The theoretical volume of organic waste is much larger than the commercially available and certified supply. Sustainability criteria can restrict energy crops and require stronger evidence that agricultural residues meet the additionality requirements. In the United Kingdom, the Green Gas Task Force found that policy, permitting, and grid access were more limiting than basic feedstock availability. Mandatory food waste collection reforms can still create more secure organic feedstock supply chains. Feedstock price volatility adds uncertainty for plant operators and contracted buyers. These pressures can slow capacity additions in the global biomethane market, even where physical waste volumes appear sufficient.

Biomethane Market Segment Analysis

Agricultural waste held 38.4% of the global biomethane market size in 2026. Its position reflects established co-digestion systems in Germany, France, Denmark, and North America, along with the need for manure management on farms. Farmers can benefit when digesters reduce handling needs for animal waste. In the United States, dairy manure represented 87% of farm-based biogas capture capacity in December 2025. Manure-only systems have a lower energy yield per tonne than food-processing waste. Developers are therefore using co-digestion models where local conditions permit.

Industrial food waste is projected to grow at an 8.7% CAGR between 2027 and 2032. Its appeal comes from high methane yields and corporate commitments to divert organics from landfill. The United States food waste-only biogas investment rose to USD 325 million in 2025. The country had 124 standalone food waste facilities operating at 27.6 bcf per year, compared with a theoretical potential of 192 bcf per year. European collection frameworks support a more organized supply of separated organics. Municipal solid waste, household organics, and sewage sludge remain relevant sources, although their growth depends on local collection systems and wastewater infrastructure.

Anaerobic digestion held 72.3% of the global biomethane market size in 2026. The process benefits from 40 years of operating experience, established suppliers, and a large installed base in Europe and North America. The IEA reported that anaerobic digestion routes produce more than 90% of current global biomethane volumes. Operators can generally bring anaerobic digestion plants online faster than newer alternatives. Better methane-to-carbon dioxide measurement can help operators improve yields and control fugitive methane. Fermentation and other processes remain limited to specialized, co-located applications.

Thermal gasification is forecast to grow at a 9.8% CAGR from 2027 to 2032. It can use dry lignocellulosic materials and solid waste that are less suitable for anaerobic digestion. The European Biogas Association describes the route as being between demonstration and early commercial deployment. It reported that thermal gasification could help expand the use of underutilized materials as projects progress toward commercial scale. The technology could provide more flexibility in regions with abundant straw, wood residues, or solid recovered fuel. It also carries a higher execution risk because commercial experience is less mature than for digestion.

Utilities commanded 34.7% of the global biomethane market size in 2026. They act as grid-injection counterparties and can aggregate supply from many small and mid-sized plants. This role gives utilities an advantage in managing gas quality, balancing, and network delivery. France’s renewable-gas certificate system creates direct demand from gas suppliers beginning in 2026. Commercial and residential users also receive biomethane through grid blending arrangements. Industrial buyers are using direct supply agreements to reduce operational emissions, while farms use biogas and biomethane in heat and machinery applications.

Transportation is projected to record a 9.2% CAGR from 2027 to 2032. Bio-CNG supports road freight, while bio-LNG can serve shipping and long-haul trucking. Renewable gas injected into European gas networks increased from 38.1 TWh in 2024 to 43.2 TWh in 2025, or 4.3 bcm, according to ENTSOG. Transport offtake represents a growing part of this activity. The global biomethane industry can benefit where fleet operators have clear fuel-credit rules and access to refueling or bunkering infrastructure. In the Asia-Pacific region, transport has become an important use case for renewable natural gas because of heavy freight and maritime demand.

Geography Analysis

Europe held an overall 35.1% share of the global biomethane market in 2026. The region has a long history of feedstock collection, gas injection, and policy support. Germany, France, Italy, Denmark, and the Netherlands accounted for 93% of European Union biomethane production. France overtook Germany as the leading grid-injection producer in 2025. Spain has EUR 4.8 billion of allocated investment intended to add 17.3 TWh of annual capacity by 2030. Poland, Ireland, and Italy are also expanding supply, and Axpo partnered on Poland’s first agricultural plant, injecting biomethane into the national grid in September 2026. National plans still need stronger execution to meet the European Union’s 35 bcm objective.

Asia-Pacific is forecast to grow at a 9.6% CAGR through 2032. India and China have large agricultural and organic waste bases that can support new projects. India’s SATAT program targets 5,000 compressed biogas plants and a 5% CBG blending mandate by 2028-29. Japan is developing its role as a potential bio-LNG import center through companies including Osaka Gas, Tokyo Gas, and Mitsui. In 2025, Asahi Kasei commissioned a biogas purification system at the Kojima Sewage Treatment Plant with a 99.5% recovery yield and 97% methane purity. Indonesia, Vietnam, and Thailand have distinct opportunities based on palm residues and rice straw.

North America holds a significant share of global volume because of the United States Renewable Fuel Standard and California’s Low Carbon Fuel Standard. Accumulated United States biogas investment reached USD 39.9 billion in December 2025. The country had 659 facilities converting biogas to renewable natural gas, compared with 217 in 2020. Canada and Mexico have less mature infrastructure and policy frameworks. Brazil leads development in South America, with BNDES approving BRL 180.7 million for 2 landfill-gas biomethane plants in 2026. The Middle East and Africa remain early-stage areas, with waste-to-energy initiatives in Saudi Arabia, the UAE, and South Africa creating possible demand.
