Work package 2 goes to the heart of the project as it involves the implementation of the innovative biomethane pathways in 5 demonstrators (in France, Greece, Italy, Sweden, and Ukraine). All activities are aimed at increasing the efficiency of biomethane production through the application of innovative technologies in demonstration and industrial scale. As such, the main tasks carried out in this WP are the preparation, planning, design and implementation of the demonstration activities in the 5 sites, including a final ‘wrap-up’, at the end of the project, to account for the findings of each pilot demo. The development of a ‘legacy’ blueprint showcasing the final results and the transferable working principles of the technologies is this WP’s conclusive task.
