The BIOMETHAVERSE electromethanogenesis team led by ENGIE gathered in March 2023 to organize the demonstration on ENGIE BIOZ plant, in Eppeville (France). As an important first step, the sub-consortium analysed the properties of the digestate feedstock that will be used for biomethane production. Coming directly from the Eppeville plant, the digestate is being analysed in the laboratory by the project partner LEITAT, responsible for the design and optimisation of the 1 chamber bioelectrochemically assisted anaerobic digestor system (1c AD-BES).

Laboratory testing of 1c-AB-BES reactors

In parallel, the partner FAU investigates on the electrodes of the reactor that best comply with all economical, efficiency and quality criteria of the project. The partner DTU makes similar studies to develop the 2 chamber bioelectrochemically assisted anaerobic digestor system (2c AD-BES), that will be adopted for converting the biogas produced by 1c AD-BES to biomethane. First designs of the process and instrumentation diagrams (P&ID) of the 2 systems (1 chamber AD-BES and 2 chamber AD-BES) are being made by the partner AERIS and last details in terms of connections, storage tanks, energy and thermal balance and are being closely discussed with the demo site to avoid any unwanted surprises. Next steps? The next quarter of 2023 will be essential for the consortium to align with all security issues before agreeing on the pilot location and date.
