With the 2030 and 2050 targets on the horizon, the biogas sector must strike a balance between acceleration and economic viability while controlling the impact on public finances. This inaugural round table, hosted by Biogaz Vallée, will take stock of the sector, regulatory developments (PPE, CPB, end of feed-in tariffs for cogeneration, etc.), innovations including hydrothermal gasification, and robust and sustainable models to be consolidated by project leaders, financiers, and public actors.

In a context of increasing litigation, Blue Broker is sharing a practical approach to anticipating litigation risk at ExpoBiogaz. As a specialized brokerage firm, we get involved right from the administrative phase to structure insurance solutions tailored to renewable energy projects, particularly in the field of methanization. The aim is to make schedules more reliable, secure financing, and strengthen the bankability of projects. Discussions can take place during the presentation or at our stand.

In response to developments in the anaerobic digestion market, project models and their financing are being reinvented. Mobilization of equity capital through participatory funds, public or private partnerships with appropriate capital contributions, bank financing, subsidized or unsubsidized tariffs: this round table, illustrated by testimonials from the field, deciphers the range of solutions available to each project leader to build financially sound and sustainable sites.

Clarke-Energy, with 36 years of expertise in gas recovery, offers turnkey solutions for biogas purification and CO2 recovery. With performance guarantees, optimal plant availability, and 24/7 local maintenance, Clarke-Energy supports each player locally to transform emissions into carbon-free opportunities in line with a sustainable circular economy approach.

As biogas projects grow in scale—with units representing investments of several million euros—the central question becomes: who is in charge, who makes the decisions, and who benefits? At OPALE, we have believed since we started our business in 2010 that biogas must remain an agricultural and regional energy source. It cannot be a simple rural version of centralized energy models. The strength of the biogas sector lies precisely in its agricultural roots, the proximity of resources, control over the return of digestate to the soil, detailed knowledge of the territories, and the direct involvement of farmers. This requires balanced partnerships, professional structuring, collective skills development, and governance that does not deprive farmers of their role. 👉 Biogas in France is happening now. 👉 And now is the time to decide who will take the reins.

Bureau Veritas supports your biogas/anaerobic digestion projects throughout their entire life cycle. We quantify methane emissions using cutting-edge technologies (IR cameras, laser spectrometers, drones), verify your regulatory compliance (ATEX, electrical, injection) and RED certify your facility. From design to operation, transform your project into a high-performance, sustainable asset with our integrated approach.

Since 2018, the Auvergne-Rhône-Alpes Region has been mobilizing key players in the sector with the Ambition Biogas 2028 Charter, led by Auvergne-Rhône-Alpes Energie Environnement. In 2025, the first TWh of biogas announced by GRDF will be achieved, proving the success of this initiative. There are many exemplary projects, both in terms of regional methanization with Bio Energies Beaujolaises, supported by a local authority, and in terms of the transition from cogeneration to injection with the Méthagora project.

Decarbonization is a complex challenge for road transport, which accounts for 30% of GHG emissions from mobility. In this context, BioNGV represents a sustainable, local, and mature solution that is highly valuable as a complement to electricity. Supported by a fairly dense network of sales outlets throughout the country and a comprehensive range of high-performance vehicles, the sector is demonstrating its operational robustness, despite the restrictive regulatory framework that is hampering its growth.

Damien Dhulst is a farmer and manages Enébio, an agricultural methanisation unit in Grand Est that recycles agricultural inputs and bio-waste to produce renewable energy (biogas/biomethane). Come and hear about his experience in the field: what really worked, points to watch out for, and the conditions for successfully integrating bio-waste into methanisation.

In 2025, players in the hydrothermal gasification (HTG) sector came together to form the HTG Cluster within Biogaz Vallée. The aim is to launch the first (pre-)industrial projects in 2026 and to develop a genuine market for this technology in France by 2028. Industrial waste is one of the first targets for the deployment of this technology: in the conference, key players set out their positions and explain the reasons for this choice.

Integrating locally produced biomethane into flat glass production: a successful European first that proves industrialization and decarbonization can go hand in hand. A round table discussion to understand the results, logistics, and prospects of a circular industry model that is already up and running.

In 2023, the first guide on the recovery of biogenic CO₂ from anaerobic digestion was published to support the development of the sector. An expanded version will be released in 2026. Discover the major new features, including: •   The conditions and requirements for producing food-grade biogenic CO₂; •   The costs associated with CO₂ recovery; •   Feedback from several projects already in operation; •   New recovery methods currently under development (CCUS) A conference organized by Biogaz Vallée in partnership with GECO₂ (Biogenic CO₂ Expert Group)

Switch to biogenic CO2 and gain independence! The rental model creates risks of disruption. Purchasing Cryolor tanks allows you to diversify your sources to green and local CO2, with a quick return on investment of 3 to 4 years. Our vacuum-insulated tanks, with a lifespan of over 35 years and no energy consumption, ensure maximum thermal efficiency for total autonomy.

The recovery of biogenic CO₂ produced by anaerobic digestion represents a source of additional revenue that strengthens the competitiveness of the sector. Its industrial use would reduce environmental impact and secure supply. The Southeast region offers favorable conditions: a dense and dynamic network of methanization units generating regular flows of CO₂, and a strong industrial presence, thus providing fertile ground for creating regional value.

Controlling the oxygen content in biomethane is now a key challenge for enabling the large-scale development of the sector. This round table will focus on the producer side and present promising solutions and initial conclusive tests.
