BIOMETHAVERSE partners gathered online in mid-June 2025 for a dynamic two-day General Assembly and Technical Workshop, to discuss progress across five demonstration sites and outline priorities for the next project phase.
The meeting confirmed that all five demonstration sites — in France, Greece, Italy, Sweden, and Ukraine — are advancing steadily, each contributing unique insights into next-generation biomethane production. From hydrogen-enhanced digestion to thermochemical methanation, the pilots are turning innovation into tangible progress.
In Italy, the CAP – SIAD – POLIMI team continues to refine its multi-pilot setup at the Bresso-Niguarda wastewater treatment plant in Milan. The site integrates four complementary units — ozonolysis, biological upgrading, microalgae treatment, and co-digestion — to create a circular and efficient model for biomethane generation.
In France, following a site change, ENGIE is finalising the installation of its electro-methanogenesis unit in Evron, a technology that converts captured CO₂ into methane using renewable hydrogen.
The Greek team (CERTH and BLAG) is completing the assembly of its fixed-bed methanation reactor, with commissioning (the first operational testing phase) planned for autumn. Designed with a modular approach to enhance scalability and maintenance, the pilot aims to reach biomethane purity levels of up to 98% once operational.
In Sweden, RISE has relocated its activities to Kalmar, focusing efforts on hydrogen addition to biogas to boost methane yield and efficiency.
And in Ukraine, MHP, supported by DBFZ and Ellmann Engineering, successfully launched its in-situ biological methanation pilot in May. The 10 m³ reactor is already in its ramp-up phase, with hydrogen injection underway and initial results showing an encouraging 5% increase in methane concentration.
Beyond the technical milestones, the Assembly celebrated BIOMETHAVERSE’s growing visibility: over 1,000 visitors have explored the project website in the past six months, generating more than 3,000 page views. The site now hosts 75 published articles, while LinkedIn engagement continues to rise, supported by EBA’s network of more than 37,000 followers. A new series of short demo videos, filmed across pilot sites, will soon bring the project’s innovation story to life for a wider audience.
The meeting closed with a clear sense of direction: as BIOMETHAVERSE enters its next phase, partners remain focused on delivering results, validating technologies, and ensuring that project outcomes translate into practical, scalable solutions for Europe’s renewable gas sector.
