Policy and transport decarbonization are central to the biomethane market. Polaris Market Research reports that the market was valued at USD 9.06 billion in 2025 and is projected to reach USD 28.15 billion by 2034, growing at a CAGR of 13.4% from 2026 to 2034. Governments worldwide are promoting production and use through financial incentives and favorable policies.

Incentives and Mandates Accelerate Deployment

Policy tools include subsidies, feed-in tariffs, tax rebates and grants, which lower the cost of production. In Europe, the Renewable Energy Directive II requires at least 14% of energy used in transportation to come from renewable sources by 2030. The US Renewable Fuel Standard and California’s Low Carbon Fuel Standard are driving investment in production facilities. Germany’s Renewable Energy Sources Act has propelled production and use, while France and the UK have robust policies such as feed-in tariffs and mandatory blending quotas. These frameworks help ensure a profitable market for producers.

Low-Carbon Transport Expands Bio-CNG and Bio-LNG

The transportation sector contributes significantly to global greenhouse gas emissions, creating demand for sustainable fuels. Germany, Sweden and the Netherlands are leading adoption of bio-CNG and bio-LNG as cleaner alternatives to diesel, particularly in heavy-duty trucking and public transportation. Fleet operators are interested because biomethane can reduce operating costs while meeting emission compliance standards, and advances in liquefaction technology and fueling infrastructure are making it viable for long-haul transport.

Maritime deals illustrate the shift. In September 2025, Shell Biogas and Hapag-Lloyd entered a long-term agreement to supply liquefied biogas, with Shell supplying bio-LNG at 22 global bunkering sites. In August 2025, Gasum signed a deal with Wasaline to supply the ferry Aurora Botnia with 100% bio-LNG, using waste-based fuel with about 90% lower lifecycle greenhouse gas emissions. The Gasum arrangement, enabled through FuelEU Maritime pooling with Stena Line, creates the first carbon-neutral shipping route across the Baltic Sea without added surcharges for passengers or cargo.

Grid Integration and Sustainability

Biomethane is fully compatible with existing natural gas infrastructure and pipelines and can be compressed or liquefied like natural gas. Technological advances in transportation and storage infrastructure make gas grid injection easier, supporting integration into existing energy systems. The fuel also fits the circular economy: it converts waste into high-quality renewable fuel compatible with net-zero goals, and growing emphasis on circular economy models strengthens demand worldwide.

In Asia Pacific, projected to grow at a CAGR of 15.72%, India’s SATAT initiative aims to establish 5,000 biomethane plants by 2025, while China’s carbon-neutrality goals also support growth.

Market Outlook and Applications

The report expects strong long-term growth, fueled by expanding renewable energy infrastructure and rising investment in low-carbon fuel alternatives. Biomethane is also used for industrial heating and power generation, and major end-use industries include transportation, utilities, manufacturing, food processing and municipal energy systems. Technological advances in purification and gas grid injection systems are improving production efficiency and commercial viability, while large-scale biomethane projects are expected to provide further opportunities.

High setup costs for production plants remain a restraint, and biomethane carries a higher production cost than natural gas because of upgrading technologies, even as natural gas faces finite reserves and increasing regulatory pressure on emissions.
