Biogas Upgrading Market: Renewable Gas Demand and Biomethane Infrastructure Expansion

The Global Biogas Upgrading Market was valued at USD 1.05 billion in 2025 and is projected to reach USD 2.32 billion by 2032, expanding at a CAGR of 12.0% during 2026–2032, according to Strategic Market Research.

 

Biogas upgrading converts variable-quality waste gas into standardized renewable fuel. Raw biogas contains methane, carbon dioxide, hydrogen sulfide, moisture and other contaminants. Upgrading systems remove these impurities and increase methane concentration so the gas can meet pipeline, transportation and industrial fuel standards.

 

The process increases the revenue potential of anaerobic digestion, landfill-gas and wastewater projects. Raw biogas is generally used close to the production site for heat or electricity. Biomethane can be injected into gas networks, compressed or liquefied for transportation, supplied to industrial facilities or traded through renewable-gas certification programs.

 

Europe had 1,975 biomethane-producing facilities across 26 countries by mid-Q2 2026, compared with 1,678 in the previous map edition. At least 86% were connected to gas grids, showing the importance of grid injection within the market. European biomethane production reached 5.2 billion cubic metres in 2024, while annual production capacity stood at approximately 7 billion cubic metres in Q1 2025.

 

Position Within the Renewable Energy Value Chain

Waste-management companies use upgrading to recover value from landfill gas and collected organic waste. Agricultural operators convert manure and crop residues into renewable fuel while reducing methane emissions. Wastewater treatment facilities produce biomethane from sewage sludge. Utilities and renewable-energy developers combine feedstock supply, gas treatment, interconnection and fuel offtake into financeable projects.

Project viability depends on the complete value chain. Efficient equipment alone cannot compensate for uncertain feedstock, limited pipeline access or weak fuel pricing. Projects with reliable organic inputs, stable gas output and contracted customers are better positioned to secure financing and long-term service agreements.

Some facilities also recover the biogenic carbon dioxide removed during upgrading. This can create an additional income stream and improve overall project returns.

 

Technology Segment Analysis

Water Scrubbing

Water scrubbing removes carbon dioxide and hydrogen sulfide by dissolving them in water, leaving methane-rich gas. It is a well-established method used in medium- and large-scale projects with steady gas supply, especially in wastewater, municipal, and agricultural applications.

The technology holds about 30–35% of the global market and is expected to grow at around 11% CAGR through 2032. Its main drawbacks include high water use, energy needs for pumping, and some methane loss.

 

Pressure Swing Adsorption

Pressure swing adsorption (PSA) uses materials such as activated carbon or zeolites to remove carbon dioxide and impurities from biogas under high pressure. The system is then regenerated by lowering the pressure.

PSA is widely used in medium and large plants, especially landfill and municipal projects, due to its reliable performance and ability to produce high-quality methane. It accounts for roughly 20–25% of the market and is expected to grow at around 12% CAGR. Proper pretreatment is important, as moisture and contaminants can affect efficiency.

Ongoing improvements focus on better materials, reduced methane loss and more efficient operation.

 

Membrane Separation

Membrane systems separate gases using selective materials, allowing carbon dioxide and impurities to pass through while retaining methane.

This technology is gaining traction due to its compact design and scalability, making it suitable for agricultural and smaller projects. It accounts for roughly 25–30% of the market and is expected to grow at a CAGR of 14%.

Challenges include energy use for compression and sensitivity to gas quality, though improved designs are enhancing efficiency and methane recovery.

 

Chemical Scrubbing

Chemical scrubbing typically uses amine-based solvents that react with carbon dioxide. The solvent is then regenerated and returned to the process.

The technology can achieve high methane purity and low methane losses. It is suitable for projects with strict pipeline specifications or carbon dioxide recovery plans. Chemical scrubbing accounts for roughly 10–15% of the market and is expected to grow at a CAGR of around 10%. However, thermal demand, solvent handling and operating complexity can make it less attractive for smaller facilities.

 

Cryogenic Upgrading

Cryogenic systems use low-temperature condensation and phase separation to produce high-purity methane. They can support bio-LNG production and liquid carbon dioxide recovery.

Europe had 101 active bio-LNG plants in 2025, with another 153 expected by 2028. This development supports demand for upgrading systems linked to heavy transport and marine fuel. Cryogenic upgrading currently holds a smaller share of about 5–10% but is projected to grow at a CAGR of 13% due to increasing bio-LNG demand. Cryogenic facilities require higher capital investment, energy input and technical control than conventional systems.

 

Raw Biogas Source Analysis

Agricultural waste is a key driver of upgrading demand, with manure and crop residues providing steady feedstock. The U.S. had 191 operating manure-based RNG systems and 69 under construction as of June 2024, supporting demand for modular upgrading solutions.

Wastewater plants also present strong opportunities, as many already use anaerobic digestion and can add upgrading to produce pipeline gas or vehicle fuel.

Landfills remain another major source, with 102 active RNG projects in the U.S. in 2023 and 444 additional sites identified as potential candidates in 2024.

Industrial sectors such as food and beverage processing generate concentrated organic waste, where onsite upgrading can lower disposal costs and reduce reliance on fossil gas.

 

Application Analysis

Grid injection is the leading application in Europe, accounting for approximately 86% market share of biomethane facilities in 2026. This segment is expected to grow at a CAGR of around 11.5% through 2032, driven by strong pipeline infrastructure and renewable-gas policies. It allows gas to be sold through pipelines and supports utility contracts and renewable-gas programs. However, connection distance and permitting can increase costs and delay projects.

Biomethane used as transportation fuel in the form of bio-CNG and bio-LNG holds an estimated market share of about 8–10% and is projected to grow at a higher CAGR of nearly 13.5% during the forecast period. Demand is increasing from buses, trucks and marine transport, supported by low-carbon fuel policies.

Industrial use accounts for roughly 3–4% of the market and is expected to expand at a CAGR of around 10.5%. It remains important for heating processes that are difficult to electrify. Long-term contracts help improve project stability, such as ENGIE’s UK project supplying PepsiCo with 60 GWh annually.

Combined heat and power represents approximately 2–3% market share and is projected to grow at a slower CAGR of about 9.0%. It is still used where grid access is limited, but upgrading is becoming more attractive due to higher-value fuel markets.

 

Market Drivers

Renewable-gas policies are driving investment in biomethane production. The European Union targets 35 billion cubic metres of biomethane by 2030, up from 4.3 billion cubic metres in 2024, supported by around 900 planned plants and EUR 28 billion in investment.

Demand is also rising from industries seeking lower-emission fuel options without replacing existing gas systems. At the same time, stricter waste-management rules and energy-security concerns are increasing feedstock availability and supporting domestic biomethane production.

 

Market Restraints and Challenges

High capital costs remain a key barrier to project development. Expenses cover digestion or gas collection, upgrading, compression, storage, grid connection and permitting. Projects rely on stable revenue from fuel sales, waste fees and incentives to remain viable.

Feedstock quality and supply can vary, affecting plant efficiency and increasing operating costs. Differences in raw gas composition also raise pretreatment needs.

Limited pipeline access and long approval timelines—often two to five years for permits plus additional time for grid connection—can delay project completion and revenue generation.

Turnkey project risks, including design changes and construction delays, can impact profitability. As a result, companies are shifting toward standardized systems and service-based models to improve margins and reduce risk.

 

Technology Trends and Innovation

Modular systems are increasing adoption among farms, smaller wastewater facilities and distributed waste projects. Standardized units reduce onsite construction and allow capacity to expand with gas production.

Advanced membrane materials are improving methane recovery while reducing energy use and equipment size. Digital monitoring, automatic process control and predictive maintenance are supporting remote operation and higher plant availability.

Carbon capture integration is also strengthening project economics. Biogenic CO₂ removed during upgrading can be purified for industrial use or permanently stored. Projects that generate revenue from both biomethane and carbon dioxide are less dependent on one fuel market.
