Anaerobic fermentation
Provision of biogas and digestate from agricultural and municipal residues
A central technology of the pilot plant for renewable methane is biogas production through anaerobic fermentation. The new focus booklet "Anaerobic fermentation | Provision of biogas and digestate from agricultural and municipal residues" offers a compact insight into the conversion of biomass into biogas and digestate. Various reactor concepts are presented and categorised in terms of efficiency, sustainability and cost-effectiveness.

Example concept
for the provision of renewable LNG from biogenic residual and waste materials and renewable hydrogen on a commercial scale
Switching from fossil fuels to renewable energies such as biofuels and electric vehicles is crucial to reduce transportation emissions. Although battery electric vehicles are promising, the low energy density of current battery technologies is an obstacle to the electrification of long-distance, heavy-duty and shipping transportation. In Germany, the use of biogenic residues offers significant potential for the production of biofuels, whether through the established technology of anaerobic digestion or the innovative approach of producing advanced fuels using renewable electricity and electrolysis. Focusing on technical design and economic-ecological assessment, this focus issue transfers research results from pilot scale to commercial scale through process simulation. The design of industrial plant concepts forms the basis for the evaluation of a relevant commercial plant.

Infrastructure for renewable methane in transport
The expansion of an infrastructure for renewable LNG has already begun in the transport sector. In recent years, numerous LNG filling stations have been built along the most important European transport routes and refueling facilities for ships. However, these are currently mainly supplied with fossil LNG, as the expansion of liquefaction capacities for renewable methane has not progressed to the same extent. The focus booklet shows the current status of the development of an infrastructure for renewable LNG for road freight transport and shipping as well as the associated challenges in dealing with the greenhouse gas methane and the sensitivity of the LNG filling station price using the example of road freight transport.

Market analysis and greenhouse gas quota
for renewable methane in transportation
The focus booklet provides an overview of the greenhouse gas avoidance quota (GHG quota) in Germany. In the model presented, the compliance options described are ranked according to the lowest specific abatement costs. The determined ranking leads to a merit order, from which the composition of the GHG quota can be derived. Conclusions can be drawn for individual fuel options, e.g. renewable methane. In addition, further market prospects for biomethane in other areas of application are identified and decisive factors for market implementation are named.

Methanation
Provision of renewable methane from biogas and hydrogen
This focus booklet provides an insight into the process of methanation, which can be used, for example, to upgrade biogas to biomethane. Catalytic and biological methanation are described in detail and compared technically, economically and ecologically. CO2 capture from biogas, which is currently used as the standard technology for biogas upgrading, serves as a reference for the evaluation. In contrast to CO2 capture, methanation offers the possibility of using almost the entire available carbon of the carbon source (e.g. biomass) for energy and material purposes. The focus booklet lists sites where the technical feasibility of methanation technologies has already been demonstrated. It also discusses the conditions under which catalytic or biological methanation is more suitable.
