19th International Bioenergy Congress
"Renewable Gases: Local energy for a more sustainable, competitive and resilient economy"
Valladolid Fair, September 29-30, 2026

The 19th International Bioenergy Congress receives 118 applications, a record number of proposals for its technical program
The 19th International Bioenergy Congress has highlighted that the development of biomethane is entering a stage where there is talk of consolidating the market, facilitating investments and moving towards a more stable and harmonized regulatory framework.
The Congress has addressed this evolution from the entire value chain, with sessions dedicated to market policies, grid connection and guarantees of origin, potential of the Spanish sector, production and upgrading technologies , valorization of digestate and biogenic CO₂, international experiences and social acceptance.
Three round tables have completed the analysis by bringing together companies and administrations to discuss the role of the public sector, the situation of biomethane in Spain with a 2030 horizon and the relationship of the projects with local communities.
Finally, in this edition, AVEBIOM has organized the World Café “Let’s Talk About Biomethane” to open a space for dialogue that directly addresses some of the concerns that accompany the implementation of new plants.
The Spanish Biomass Association, organizer of the 2026 International Bioenergy Congress, invites researchers, academics, and professionals in the sector to submit their papers for the next edition of the congress.
This year, under the theme "Renewable Gases: Local Energy for a More Sustainable, Competitive, and Resilient Economy," we are focusing on the role of biomethane and other renewable gases in the energy transition. We will analyze their real impact on business competitiveness, energy security, and the decarbonization of industry, with concrete examples of their implementation in various sectors. Are we ready to harness their full potential and reduce our dependence on fossil fuels? The 19th International Bioenergy Congress is the place to discuss this.
The selection of presentations will seek to foster discussion on the potential of renewable gases in the Spanish market ; renewable gas technologies ; the use of by-products from biogas generation ; international experiences; and social acceptance.
