The threshold value for sustainability certification of 2 MW remains in place.As an outlook on the political situation for 2024, Dr Rauh pointed out that Berlin is now also focusing on biogas and wants to expand 6 GW of biomass, including 3 GW of biomethane.Whether NABIS will be a signalling device, however, remained open.

Among other things, the German Biogas Association is calling for balance sheet divisibility to be made possible again and for endogenous volume control to be abolished.If politicians do not create incentives now, there is a risk of a net dismantling of biogas plants in the coming years.

Mr Höckner from the Austrian company BioG presented his farm filling station as an economically interesting addition to existing and new biogas plants. A membrane is integrated into the fuelling station, making it an option for locations where no biogas upgrading plant is installed.

Martin Laß from BioEnergie Gettorf GmbH spoke on the subject of biogas as a nucleus for large heating projects and described the path from a biogas plant to a CO2-neutral neighbourhood. He gave an impressive description of sector coupling as a future solution for the energy transition.

Werner Schleupen from the Schleupen biogas plant spoke on the subject of green hydrogen. He described the production of hydrogen from biogas with steam reformation using the practical example of BtX energy.

Maximilian Schmitt, Reverion GmbH, then presented their system. This is a plug&play solution that works with an efficiency of 80%, CO2-negative.In reversible operation, the plant can generate electricity from biogas with an electrical efficiency of 80% as well as water and CO2. Through electrolysis, the plant can absorb excess electricity and generate CH4 or H2.Finally, Prof. Weinrich spoke on the topic of automated process management of biogas plants and Roland Schulze Lefert from the NRW Chamber of Agriculture spoke on the economic viability of biogas in the KWKG and in the innovation tender.
