Biogas Market Size, Share and Outlook - Growth Analysis Report and Forecast Trends 2026-2030

The biogas market covers technologies and services that capture methane from decomposing organic matter and convert it into electricity, heat, vehicle fuel, or upgraded biomethane injected into natural-gas grids. The industry is in a phase of strong commercial scale-up, with the global installed base of biogas capacity expected to surpass 28 GW by 2031. Demand is reinforced by the parallel growth of digestate, a nutrient-rich byproduct increasingly valued as a substitute for synthetic fertilizers.

• •2025 market valuation stands at approximately $77.88 billion, with a compound annual growth rate near 7.08%.
• •Core feedstocks include biowaste, municipal solid waste, sewage sludge, and agricultural residues.
• •End products range from combined heat and power to upgraded biomethane and compressed/liquefied bio-methane transport fuels.

Decarbonization commitments from major economies, combined with subsidies and renewable-fuel mandates, are accelerating project pipelines across regions. The growing volume of organic waste from expanding urban populations and intensive agriculture is creating a reliable feedstock base, while energy-security concerns following recent fossil-fuel price volatility are pushing utilities and industrial gas users to diversify. Carbon-credit revenue streams and circular-economy regulations further improve project economics.

• •Net-zero and renewable-energy targets in the EU, North America, and Asia are driving policy support and feed-in tariffs for biogas.
• •Rising organic-waste volumes from cities, food processors, and livestock operations are increasing the available feedstock.
• •Demand for renewable natural gas as a drop-in substitute for pipeline gas is broadening the market beyond electricity generation.

By feedstock, agricultural waste and energy crops currently account for the largest share, though municipal biowaste and sewage-based applications are growing rapidly as cities modernize waste infrastructure. Europe holds the leading regional position due to long-standing feed-in tariffs, a mature biomethane grid-injection network, and stringent waste directives, while Asia-Pacific is the fastest-growing region on the back of large agricultural economies in China and India and aggressive waste-to-energy programs in Southeast Asia. North America is expanding through renewable natural gas (RNG) projects tied to landfill and dairy operations.

• •Europe leads in installed capacity and biomethane grid injection, with Germany, France, and the Nordics as anchor markets.
• •Asia-Pacific is the fastest-growing region, supported by agricultural waste availability and government-led clean-energy programs.
• •By application, electricity and heat generation remain dominant, while transportation fuel and grid biomethane are the highest-growth segments.

What are the recent trends and outlook?

The outlook through the 2030s points to continued double-digit expansion of renewable natural gas capacity, supported by binding climate targets and the scaling of carbon pricing. Upgrading of biogas to biomethane is the single most influential technical trend because it unlocks higher-value end markets including heavy transport, shipping, and industrial gas. Digital monitoring, co-digestion of multiple waste streams, and integration with green hydrogen and carbon-capture projects are emerging as the next frontier of value creation.

• •Biomethane grid injection and RNG for transport are expected to outpace traditional combined-heat-and-power growth.
• •Co-digestion of food waste, manure, and crop residues is improving plant economics and community acceptance.
• •Long-term offtake deals with utilities, fuel retailers, and industrial gas users are becoming the standard financing model for new projects.
