The European biomethane market is experiencing unprecedented growth. According to the latest “Biomethane Investment Outlook” report by the European Biogas Association (EBA) from June 2025, the total volume of planned investments in biomethane production has reached €28.4 billion. This highlights a powerful trend towards decarbonization and Europe’s push for energy self-sufficiency.
For companies in the agricultural and energy sectors, these are not just numbers—they are a direct call to action and a gateway to new opportunities.
The Scale of Growth: Hundreds of New Plants and Billions of Cubic Meters of Gas
The EBA report, based on data from leading investors and project developers, paints an impressive picture of the future. The planned investments are set to deliver an additional 7.3 billion cubic meters of biomethane annually, with 6.7 billion of that to be produced in Europe.
Most importantly, nearly 900 new biomethane plants are expected to be launched within the next five years. This means that the demand for reliable infrastructure—from raw material storage systems to digestate tanks—will grow exponentially.
Key Facts from the Report:
-
€28.4 billion – total volume of announced investments.
-
85% of investments (€24.2 billion) are allocated to “greenfield” projects, meaning entirely new plants built from scratch.
-
Nearly 900 new plants are planned for commissioning in the next 5 years.
Geography of Investments: Who is Leading the Biomethane Race?
Investments are spread across Europe, but there are clear leaders setting the pace. The largest capital investments are planned in the following countries:
-
Spain – €4.8 billion
-
Denmark – €3.14 billion
-
United Kingdom – €2.43 billion
-
France – €1.71 billion
-
Italy – €1.31 billion
-
Poland – €1.09 billion
Poland is particularly noteworthy, as Flexsol has a long-standing and successful manufacturing presence there. The planned investments of over €1 billion in the Polish biomethane market only confirm the huge potential of a region where we are already a reliable and proven partner. Our deep integration, extensive experience, and local presence allow us to offer the best solutions for ambitious new projects being implemented across the European Union.
What Does This Mean for Business?
Every new biomethane plant is a complex facility that requires dependable solutions at every stage of production. Since 85% of new projects are being built “from scratch,” the need for infrastructure is at its peak.
This is where solutions from Flexsol become crucial:
-
Raw Material Storage: Efficient operation of a biogas plant requires a constant supply of raw materials (silage, manure, waste). Large-volume flexible tanks are an ideal and cost-effective solution for their storage.
-
Digestate Storage: After fermentation, valuable organic fertilizers (digestate) are produced. Our flexible tanks and lagoon liners ensure hermetic and environmentally safe storage of these fertilizers before they are applied to the soil.
-
Gasholders: For the temporary storage of produced biogas before it is upgraded to biomethane, special membrane gasholders are used, which are also part of our product range.
The trend outlined in the EBA report clearly shows that the future belongs to sustainable energy. Investing in biomethane is not only a contribution to the environment but also an extremely promising business direction. Flexsol is ready to become a reliable partner for everyone planning to join this energy revolution, offering proven and effective storage solutions for every stage of biomethane production.
