Biogas and Biomethane in France: Market Growth, Policy and 2030 Outlook

Biogas and biomethane production in France has moved from an emerging renewable-energy opportunity to a substantial national industry. France now operates one of Europe’s largest fleets of biomethane-to-grid plants, supported by agricultural feedstocks, municipal and industrial organic wastes, established gas infrastructure and government-backed market mechanisms.

When we last reviewed the French market in 2022, we said that biomethane injection was expanding rapidly and that France could become one of Europe’s most important renewable-gas producers. That central prediction was correct.

However, the route taken by the industry has been less straightforward than our earlier article suggested. The energy crisis following Russia’s invasion of Ukraine strengthened the strategic case for domestic renewable gas, but it did not permanently guarantee exceptional project profitability. Construction inflation, higher interest rates, changing tariffs, planning delays, feedstock competition and public opposition have all complicated development.

The result is a French biomethane sector that is much larger and more mature than it was in 2022, but which must now make another difficult transition: from rapid early deployment supported mainly by feed-in tariffs to a much larger market combining regulated support, biogas production certificates, guarantees of origin and commercial biomethane purchase agreements.

Latest position at a glance:

• France had 823 biomethane injection installations in operation by 31 March 2026.
• Their combined maximum injection capacity was approximately 15.9 TWh per year.
• France injected approximately 13.5 to 13.6 TWh of biomethane during 2025.
• Biomethane supplied approximately 3.9% of French gas consumption in 2025.
• A further 1,227 projects, representing about 20.8 TWh per year of capacity, were in the development queue at the end of March 2026.
• France’s third Multiannual Energy Programme, known as PPE3, sets a target of 44 TWh of injected biomethane in 2030.

Key Takeaways

How Much Has the French Biomethane Market Grown?

France’s progress since the late 2010s has been remarkable. Biomethane injection was still a relatively small activity in 2017, but the number of commissioned plants increased rapidly through the early 2020s.

By the end of 2024, France had 731 operational injection installations with a combined capacity of approximately 13.9 TWh per year. During 2024, 11.6 TWh of biomethane was injected into the gas networks, an increase of 27% compared with the previous year.

Growth continued during 2025. Official and gas-industry figures indicate that just over 800 sites were injecting by the end of that year, producing approximately 13.5 to 13.6 TWh. This was equivalent to about 3.9% of French gas consumption.

By 31 March 2026, the official government dashboard recorded 823 operational installations and 15.9 TWh per year of maximum injection capacity.

Were Our 2022 Predictions Correct?

The original article made several broad predictions about the direction of the French market. Some have aged well. Others require qualification.

Prediction 1: France would become one of Europe’s major biomethane markets

Verdict: Correct.

France is now among Europe’s leading biomethane markets, particularly when measured by its number of injection installations. Its growth has been driven by a distributed model involving many agricultural and territorial projects rather than relying solely on a small number of very large plants.

This has created a geographically dispersed industry that links renewable-gas production with farming, manure management, crop residues, food-processing wastes, municipal biowaste and local gas networks.

Prediction 2: Grid injection would become the dominant development route

Verdict: Largely correct.

France has clearly prioritised upgrading biogas to biomethane and injecting it into existing gas infrastructure. This route allows renewable gas to serve homes, commercial users, industry, district energy systems and transport without requiring each production plant to be located beside the final consumer.

Biogas-fired combined heat and power remains part of the French market, especially at older installations and sites with a reliable local heat demand. Nevertheless, grid injection has become the leading growth segment.

Prediction 3: The Ukraine energy crisis would assure strong profitability

Verdict: Only partly correct.

The crisis dramatically improved the strategic value of domestic gas production and temporarily raised wholesale gas prices. It also reinforced political interest in energy sovereignty.

However, it was too optimistic to imply that profitability would therefore be assured. Biomethane project economics are influenced by much more than the wholesale gas price. They depend on:

• the applicable purchase tariff or commercial gas-sale price;
• eligibility for guarantees of origin or biogas production certificates;
• capital cost and financing terms;
• the cost and security of feedstock supplies;
• grid connection and reinforcement expenditure;
• plant availability and methane yield;
• digestate storage, transport and spreading costs;
• planning conditions and environmental controls;
• the cost of odour, noise and traffic mitigation;
• and the plant’s long-term maintenance requirements.

Projects with reliable feedstocks, good engineering, an accessible gas connection and strong operational management can perform well. Poorly located or over-leveraged schemes remain vulnerable.

Prediction 4: Technology improvements would substantially reduce costs

Verdict: Partly correct, but offset by wider inflation.

Biogas upgrading systems, gas-quality monitoring, biological desulphurisation, membrane separation and injection equipment have all become more established. Developers and network operators also have far more experience than they did a decade ago.

Against those improvements, the sector has faced major increases in civil-engineering prices, steel costs, electrical equipment prices, labour rates and borrowing costs. The cost-reduction story has therefore not been as simple as expected.

Prediction 5: Local opposition would remain an important constraint

Verdict: Correct.

Community concerns have not disappeared. The most common objections continue to involve odour, heavy-vehicle movements, road safety, landscape effects, noise, feedstock storage, digestate spreading and doubts about the types of material a plant may accept in future.

The strongest projects normally address these issues before submitting their planning applications. Developers who treat community engagement as a public-relations exercise after the design has been fixed are more likely to encounter opposition.

France’s New 44 TWh Biomethane Target

The most important change since the 2022 article is the publication of France’s third Multiannual Energy Programme, PPE3, in February 2026.

PPE3 establishes a target of 44 TWh of biomethane injected into the French gas networks in 2030. It also sets a wider range of approximately 47 to 82 TWh by 2035.

This is far more ambitious than the earlier target discussed in our 2022 article. It implies that France must increase injected biomethane production from about 13.6 TWh in 2025 to 44 TWh only five years later.

The development queue provides some grounds for confidence. At the end of March 2026, 1,227 projects representing 20.8 TWh per year of additional capacity were recorded in the connection queue.

Nevertheless, a project queue should not be confused with completed capacity. Some schemes will be delayed, resized or cancelled. Even if the entire queue were commissioned, additional capacity and higher utilisation would still be needed to achieve 44 TWh of actual annual injection.

Why France Has Been Successful

1. Extensive gas-distribution infrastructure

France already possesses a large gas-distribution and transmission network. This provides an established route to market for biomethane and allows production in rural areas to serve consumers elsewhere.

Network operators including GRDF, NaTran and regional operators have gained considerable experience in assessing connections, monitoring gas quality, managing capacity and introducing reverse-flow installations where local production exceeds local gas demand.

2. Strong agricultural participation

French agriculture has been central to the biomethane expansion. Agricultural installations can combine livestock manures, crop residues, catch crops, food-processing residues and other permitted organic materials.

For farmers, a well-planned anaerobic digestion plant can provide:

• an additional and more predictable income stream;
• improved manure management;
• renewable heat or gas for farm use;
• production of digestate fertiliser;
• reduced dependence on imported mineral fertilisers;
• and diversification away from volatile agricultural commodity prices.

These benefits should not be overstated. Anaerobic digestion is an industrial biological process that demands skilled management, preventive maintenance, feedstock control and careful nutrient planning. It is not a passive investment.

3. Long-term revenue support

France’s guaranteed biomethane purchase arrangements gave developers and lenders a long-term revenue framework. Qualifying installations have been able to sell injected biomethane under regulated contracts, with tariffs varying according to plant characteristics and capacity.

The tariff framework has been revised several times. The current structure is linked to the purchase-tariff order of 13 June 2023, with coefficients and degression factors reviewed periodically by the French Energy Regulatory Commission.

4. Growing importance of energy sovereignty

Before 2022, biomethane was promoted mainly as a climate, waste-management and rural-development measure. Following the disruption of European gas markets, it also became an energy-security measure.

Every unit of biomethane produced from French organic resources can displace some imported fossil gas. It cannot replace all conventional gas consumption, but it can contribute to a smaller, more resilient and progressively decarbonised gas system.

How French Biomethane Projects Are Supported

The market is moving towards a mixed support structure rather than relying on one mechanism.

Regulated biomethane purchase tariffs

Eligible smaller and medium-sized injection installations may obtain a long-term purchase contract under the regulated tariff framework. The detailed tariff depends on factors including plant size, commissioning date, feedstock category and the applicable indexation and degression coefficients.

Anyone assessing a new French project should use the current tariff order and the latest coefficients published by the Commission de régulation de l’énergie. Historic tariff values should not be used in a new financial model.

Certificats de Production de Biogaz

France has introduced Certificats de Production de Biogaz, usually abbreviated to CPB. This mechanism places obligations on gas suppliers and is intended to stimulate new injected biomethane production while reducing exclusive dependence on direct state-funded tariffs.

Eligible biomethane producers receive certificates for qualifying gas production. Obligated gas suppliers must acquire and surrender the required number of certificates.

The mechanism is important because France’s 44 TWh target would be difficult to finance solely through the traditional tariff model. However, the industry continues to seek long-term clarity over certificate volumes, values and the trajectory beyond the late 2020s.

Guarantees of origin

Guarantees of origin provide evidence that an equivalent quantity of renewable gas has been produced and injected into the network. They allow gas consumers to make renewable-gas purchasing claims under the applicable accounting and regulatory rules.

A guarantee of origin does not mean that the physical biomethane molecules are delivered through a dedicated pipe to the named customer. The gas is mixed within the network, while the certificate records the renewable attribute.

Biomethane purchase agreements

Direct commercial contracts, often described as Biomethane Purchase Agreements or BPAs, are beginning to supplement regulated support. Under these agreements, an industrial or energy buyer contracts for biomethane and its environmental attributes over an agreed period.

BPAs could become increasingly important for larger plants and corporate buyers seeking long-term renewable-gas supplies without relying entirely on a government purchase tariff.

Where Does French Biogas Come From?

French biogas and biomethane installations use several categories of biodegradable material:

• cattle, pig and poultry manures;
• slurries and other livestock effluents;
• crop residues;
• intermediate and catch crops grown within agricultural rotations;
• food and drink manufacturing residues;
• separately collected household and commercial food waste;
• sewage sludge;
• landfill gas;
• and other permitted biodegradable industrial wastes.

The environmental outcome depends heavily on the feedstock mix and the way it would otherwise have been managed.

Capturing methane from manure, sewage sludge, landfill gas and unavoidable organic wastes can deliver substantial greenhouse-gas benefits. By contrast, excessive dependence on purpose-grown energy crops may create competition for land, increase transport movements and weaken the overall sustainability case.

The Role of Intermediate Energy Crops

France has developed considerable interest in cultures intermédiaires à vocation énergétique, commonly known as CIVE. These are intermediate crops grown between principal food or forage crops and used as anaerobic-digestion feedstock.

Supporters argue that well-managed CIVE can:

• provide winter soil cover;
• reduce erosion and nutrient loss;
• produce additional farm biomass without directly displacing the principal crop;
• support crop rotations;
• and provide a stable feedstock for digesters.

Critics warn that poorly designed systems may increase irrigation, fertiliser use, soil pressure and competition for agricultural resources.

The correct conclusion is not that all intermediate crops are either good or bad. Their sustainability depends on local climate, water availability, rotation design, fertiliser use, crop yield, land management and the proportion of the digester feedstock they supply.

Digestate: Valuable Fertiliser, but Not Impact-Free

Anaerobic digestion produces digestate as well as biogas. Digestate retains most of the nitrogen, phosphorus, potassium and trace nutrients present in the input materials.

It can replace part of a farm’s purchased fertiliser requirement and may provide nutrients in a more immediately available form than untreated manure.

However, digestion does not remove nutrients. Poorly timed or excessive digestate application can cause nitrate leaching, ammonia emissions, odour and surface-water pollution.

Good practice requires:

• adequate covered storage capacity;
• a nutrient-management plan;
• analysis of digestate composition;
• application at agronomic rates;
• appropriate separation distances from watercourses and sensitive receptors;
• low-emission spreading equipment;
• and sufficient suitable land within an economic transport distance.

Methane Leakage Must Receive More Attention

Methane is the valuable product of an anaerobic digestion plant, but it is also a powerful greenhouse gas. Uncontrolled releases can significantly reduce the climate benefit of biomethane.

Potential emission points include:

• pressure-relief valves;
• digestate storage tanks;
• upgrading-system off-gas;
• poorly sealed digesters and pipework;
• condensate systems;
• compressors and valves;
• emergency flares;
• and maintenance activities.

Modern plants should incorporate leak-detection and repair procedures, routine gas-balancing, enclosed or covered digestate storage, effective flare management and suitable treatment of upgrading off-gas.

As the French fleet expands, operational emissions monitoring will become at least as important as construction of new capacity.

Grid Capacity and Reverse Flow

Biomethane plants frequently connect to rural gas-distribution networks where demand varies greatly between winter and summer. A network may accept all available biomethane during cold weather but become constrained when local summer gas consumption falls.

Solutions include:

• reinforcement of the local network;
• connection to a higher-pressure pipeline;
• reverse-flow stations that transfer gas from the distribution system into the transmission network;
• coordination of several local producers;
• temporary production management;
• and, where practical, local transport-fuel or industrial use.

France has invested in network adaptation, but connection capacity remains a decisive project-development issue. Developers should obtain a realistic network study at an early stage rather than assuming that the nearest gas main can accept the proposed output.

Biomethane for Transport in France

French biomethane can also be used as BioGNV, the renewable equivalent of natural gas for vehicles. It may be supplied as compressed biomethane or, following liquefaction, as liquefied biomethane.

Potential applications include:

• buses;
• refuse-collection vehicles;
• regional delivery fleets;
• heavy goods vehicles;
• agricultural machinery;
• and captive commercial fleets.

Battery-electric vehicles are likely to dominate many light-duty applications. Biomethane may remain valuable where vehicles require long range, rapid refuelling, high payload or intensive daily operation.

Its strongest climate case usually arises when the gas is produced from manure, sewage, food waste or another residue that might otherwise release methane.

Food Waste and Municipal Biowaste

European requirements for separate biowaste collection are increasing the amount of source-separated food and garden waste available for biological treatment.

France’s implementation of source separation creates an opportunity for anaerobic digestion, particularly where food waste can be converted into biomethane before the digestate or fibre fraction receives further treatment.

Successful municipal and commercial food-waste digestion depends on:

• low contamination at the point of collection;
• effective depackaging without excessive fragmentation of plastics;
• removal of grit, glass and metals;
• appropriate hygienisation;
• stable digestion;
• and a reliable outlet for the resulting digestate.

Increasing food-waste quantities should not be treated simply as a source of cheap digester feedstock. Collection quality and contamination control will determine whether the material creates value or operational problems.

Public Opposition and Planning Risk

The expansion of French methanisation has prompted increasingly organised opposition in some regions. Concerns vary considerably between projects and should not all be dismissed as misunderstanding.

Legitimate planning questions include:

• How many vehicle movements will occur each day?
• Which roads will delivery vehicles use?
• Will feedstocks be stored in enclosed or open areas?
• How will odour be contained during reception and mixing?
• What materials will the permit allow the plant to accept?
• How will digestate be stored and spread?
• What happens during equipment failure?
• Will the plant use substantial quantities of purpose-grown crops?
• How will methane leakage be measured?
• What fire, explosion and gas-release controls will be provided?

Developers should answer these questions with site-specific evidence. General statements about renewable energy do not replace a credible traffic assessment, odour-management plan, nutrient plan or emergency-response procedure.

Can France Reach 44 TWh by 2030?

It is technically possible, but the timetable is demanding.

France has several advantages:

• a large agricultural resource base;
• mature gas networks;
• experienced network operators;
• hundreds of operating reference plants;
• a substantial project pipeline;
• established equipment and service companies;
• and a clear strategic need to replace imported fossil gas.

The barriers are equally real:

• planning and permitting timescales;
• uncertainty over future support mechanisms;
• high capital and financing costs;
• limited grid capacity in some areas;
• feedstock competition;
• construction-sector capacity;
• community opposition;
• and the need to maintain high environmental standards during very rapid growth.

Installed capacity would need to rise from 15.9 TWh per year in March 2026 to well over 44 TWh if actual annual injection is to reach the target. This is because plants do not normally operate at their theoretical maximum output every hour of the year.

Consequently, the 2030 target should be regarded as ambitious rather than assured.

Business Opportunities in the French Biogas Sector

France remains an attractive market for companies with relevant experience, but it is no longer an immature market in which generic technology can easily gain a foothold.

Opportunities are likely to include:

• biogas upgrading and compression systems;
• methane-slip reduction;
• gas-quality measurement;
• feedstock pre-treatment;
• food-waste depackaging and contaminant removal;
• digester mixing and pumping;
• biological and activated-carbon desulphurisation;
• digestate separation and nutrient recovery;
• covered digestate storage;
• reverse-flow and grid-injection infrastructure;
• carbon-dioxide recovery and liquefaction;
• plant optimisation and capacity expansion;
• conversion from combined heat and power to biomethane injection;
• leak-detection and repair services;
• and independent technical due diligence.

Suppliers entering the French market must understand French permitting, gas-quality standards, language requirements, agricultural practices and the expectations of network operators. A technically adequate product without local service and compliance support may struggle to compete.

What Has Changed Most Since 2022?

The greatest change is not simply the number of plants. It is the scale of France’s ambition.

In 2022, discussion focused on whether France could reach 14 to 22 TWh of biomethane injection by 2028 and obtain around 10% of its gas from renewable sources by 2030.

By early 2026, France already had 15.9 TWh per year of installed injection capacity. The new national programme now calls for 44 TWh of actual injected biomethane in 2030.

This confirms that our 2022 optimism about market growth was justified. It also shows that the industry’s next stage will be much harder than the first.

The early market could expand through hundreds of relatively conventional agricultural projects backed by regulated purchase tariffs. Reaching 44 TWh will demand larger volumes, faster connection, optimisation of existing assets, new commercial models and consistently high environmental performance.

Conclusion

France has transformed its biomethane sector in less than a decade.

The country progressed from almost negligible grid injection in the mid-2010s to more than 800 operating injection installations by early 2026. Annual output reached approximately 13.6 TWh in 2025, equivalent to about 3.9% of French gas consumption.

Our 2022 article was therefore correct to identify France as one of Europe’s fastest-growing and most promising biomethane markets.

It was less accurate to imply that high gas prices would make profitability straightforward or that falling technology costs would dominate project economics. In practice, successful biomethane development still depends on sound engineering, secure feedstocks, affordable finance, grid access, environmental compliance and competent long-term operation.

The new PPE3 target of 44 TWh in 2030 demonstrates strong political ambition. Whether France achieves it will depend on how effectively the country converts its substantial development pipeline into reliable operating production.

Whatever the precise 2030 outcome, biomethane has already secured a significant place in France’s energy, agricultural and circular-economy policies. It is no longer a speculative future technology. It is an established industry entering a more demanding phase of growth.

Frequently Asked Questions

How many biomethane plants are operating in France?

Official French statistics recorded 823 installations injecting biomethane into the gas networks on 31 March 2026.

How much biomethane does France produce?

France injected approximately 13.5 to 13.6 TWh of biomethane during 2025. Installed maximum injection capacity had risen to 15.9 TWh per year by March 2026.

Biomethane represented approximately 3.9% of French gas consumption in 2025, up from about 3.2% in 2024.

What is France’s biomethane target for 2030?

France’s PPE3 energy programme sets a target of 44 TWh of biomethane injected into the gas networks in 2030.

Is France likely to reach its 2030 biomethane target?

The target is technically achievable but highly ambitious. France has a large project pipeline, but it must commission capacity rapidly, overcome grid and planning constraints and ensure that plants achieve strong operational availability.

What are the main feedstocks for French anaerobic digestion plants?

Feedstocks include livestock manure, slurry, crop residues, intermediate energy crops, food-processing residues, municipal food waste, sewage sludge and other permitted biodegradable materials.

Does France subsidise biomethane?

Yes. Eligible projects may benefit from regulated purchase tariffs. France is also developing certificates of biogas production, guarantees of origin and private biomethane purchase agreements.

What are Certificats de Production de Biogaz?

They are certificates issued for qualifying injected biomethane production. Obligated gas suppliers must obtain certificates, creating an additional market-based support mechanism for new production.

Is biomethane carbon neutral?

Not automatically. Biomethane is renewable, but its lifecycle emissions depend on feedstock production, methane leakage, transport, plant energy use, digestate management and the fossil fuel or waste practice it replaces.

Why is biomethane important to French farmers?

It can provide income diversification, improved manure management, renewable energy and digestate fertiliser. However, a digester also creates substantial financial, operational and regulatory responsibilities.

Can biomethane replace all fossil natural gas in France?

Not at present. It can replace a growing proportion of fossil gas, especially in difficult-to-electrify industries, heavy transport and existing gas uses. Energy efficiency and electrification will also be necessary as total fossil-gas consumption declines.
