000909831 520__ $$aThe indirect electrification of the sectors heating, mobility and chemical industry by power-to-X processes may play a significant role in transforming our energy system, because not all processes can easily use electrical power directly. The high-temperature co-electrolysis is particularly well suited to produce synthesis gas as feedstock for various power-to-fuel and power-to-chemicals processes.Besides the energy- and cost-intensive direct air capture, biogenic carbon dioxide emissions are promising candidate for supplying the CO2. Biogas contains between 30 - 50 vol. % of CO2 besides methane and trace impurities and is available in a significant amount in Europe. The biogas can be upgraded by separating the CO2 and methane. However, since the upgrade plants add additional costs and the combination is often not economically viable, biogas is in most cases directly burned in CHP plants.To harness the significant carbon potential of biogas, an oxyfuel combustion may be used, which avoids the dilution of CO2 with nitrogen from the air and emits a mixture of steam and CO2 that could be used directly in a co-electrolysis system for re-usage of CO2. Recent investigations show, that this mixture can be supplied for low costs by retrofitting existing biogas combustion to an oxyfuel combustion. This contribution will investigate the performance and operation of short-stacks containing Ni/YSZ-based solid-oxide cells with simulated flue gases from such a biogas-oxyfuel process.However, biogas also contains trace impurities originating from the biomass, foremost sulfuric species and siloxanes. Before combustion, these are partially removed from the gas, but some traces remain and are converted to oxidized combustion products. In particular, the impact of these oxidized contaminants on the degradation behavior of the cells will be considered and experimentally investigated.
