The global push toward sustainability and decarbonization has led to increasing interest in renewable energy sources. Among these, green methane has emerged as a promising fuel due to its ability to serve as a low-carbon substitute for natural gas. Derived primarily through power-to-gas (PtG) processes or anaerobic digestion of organic matter, green methane provides a pathway to utilize existing gas infrastructure while lowering greenhouse gas emissions.
According to recent market data, the global green methane market size was valued at USD 2820.2 million in 2023 and is projected to grow from USD 3253.9 million in 2024 to USD 9059.7 million by 2031, exhibiting a CAGR of 15.75 percent during the forecast period. This sharp growth reflects expanding government support, technological advancements, and increasing corporate commitments to net-zero goals.
Market Overview
Green methane, often referred to as renewable natural gas (RNG) or synthetic methane, is produced by upgrading biogas or synthesizing methane from hydrogen and captured carbon dioxide. It has applications in power generation, heating, transportation, and industrial processes.
Key market dynamics include:
- Rising demand for renewable energy to replace fossil fuels
- Supportive policies and subsidies for clean energy projects
- Advancements in electrolysis and methanation technologies
- Growing interest in decarbonizing hard-to-abate sectors such as heavy transport and industry
The current valuation of over USD 2.8 billion highlights the early momentum of this market. With projections exceeding USD 9 billion by 2031, green methane is set to play a critical role in the future energy mix.
Drivers of Market Growth
Decarbonization Goals
Global climate agreements and national commitments to reduce emissions have created strong incentives for renewable energy development. Green methane aligns with these targets by providing a carbon-neutral alternative that can be injected into existing natural gas grids without major infrastructure overhauls.
Energy Security
Geopolitical tensions and volatility in fossil fuel prices have pushed governments and corporations to diversify their energy sources. Locally produced green methane can strengthen energy independence and reduce reliance on imported natural gas.
Technological Advancements
Electrolyzers, carbon capture systems, and methanation reactors are becoming more efficient and cost-effective. This has lowered production costs, making green methane more competitive with conventional fuels.
Circular Economy and Waste Management
Green methane production often uses organic waste, agricultural residues, and municipal solid waste. This not only provides a renewable fuel but also helps in waste management and the reduction of methane emissions from landfills.
Market Challenges
Despite strong growth prospects, the green methane industry faces several challenges:
- High production costs compared to fossil-based natural gas
- Limited large-scale infrastructure for renewable gas injection in certain regions
- Competition from other renewable energy sources, such as hydrogen and direct electrification
- Policy uncertainty in some countries, where incentives for renewable gases are still under development
Overcoming these challenges will require coordinated efforts from policymakers, technology developers, and energy companies.
Regional Insights
The global market for green methane exhibits strong regional variation, shaped by energy policies, infrastructure readiness, and technological adoption.
Europe
Europe currently leads the market, driven by the European Union’s aggressive decarbonization agenda. Countries such as Germany, Denmark, and France have established supportive frameworks for renewable gas injection and carbon-neutral energy. The EU’s “Fit for 55” package and REPowerEU plan further incentivize investment in green methane projects.
North America
The United States and Canada are emerging as significant markets due to policies like the Renewable Fuel Standard and Low Carbon Fuel Standard. RNG is particularly gaining momentum in the transportation sector, where it qualifies for carbon credits.
Asia-Pacific
The Asia-Pacific region, led by China, Japan, and India, is expected to witness substantial growth. Rapid industrialization, urbanization, and rising energy demand are pushing governments to adopt cleaner energy solutions. Japan’s hydrogen and synthetic methane projects and India’s National Bio-Energy Mission illustrate this trend.
Rest of the World
Latin America, the Middle East, and Africa are in the early stages but show potential. Brazil’s strong bioenergy sector and Africa’s abundant biomass resources can support future growth in green methane production.
