Abstract:
The Pilot-SBG (Pilot plant Synthesized BioGas) project supports amongst others the development of innovative and sustainable value chains for producing renewable methane, based on biogenic waste and residues streams from urban and rural areas and hydrogen as well within a circular economy. The focus of the investigations at the pilot plant and the accompanying feasibility and market analyses is on different value chains and scenarios for biogas-based methane and the integration of green hydrogen to increase the methane yield. Due to the core processes of the plant, anaerobic digestion with subsequent catalytic methanation, the product stream contains both methane from biogas (declared as advanced biofuel in RED II) and methane from the methanation of the CO2 from the biogas with green hydrogen (declared as RFNBO). Following the definitions and requirements for biofuels and RFNBOs defined in RED II, special attention lies on different approaches and perspectives to assess and declare the product stream. The assessed liquefied renewable methane will achieve the specific GHG reduction target regardless of the approach chosen. But the different methodologies lead to disadvantages on the part of the produced advanced biofuels.
