      abstract     = {Producing synthetic fuels via Power-to-Fuel processes
                      requires hydrogen and a carbon source. To attain a
                      sustainable fuel, both reactants must originate from a
                      renewable source. For the carbon source, biogas plants offer
                      substantial potential. Hence, this paper presents a new
                      biogas-oxyfuel process that couples a biogas plant with
                      Power-to-Fuel production and enables a decentralized and
                      economical supply of biogenic carbon dioxide for the
                      production of renewable methanol. By using the oxygen
                      byproduct of the Power-to-Fuel synthesis in the oxyfuel
                      combustion of a combined heat and power unit, a simple
                      separation of the CO2 in the flue gas is made possible. To
                      analyze the thermodynamic changes within the combustion
                      engine when switching from regular to oxyfuel combustion, an
                      AspenPlus model of the combined heat and power unit of a
                      biogas plant is built up herein. Due to the higher heat
                      capacity of the new working gas carbon dioxide in comparison
                      to nitrogen, the ideal Otto engine cycle’s mechanical
                      efficiency drops by percentage point. This drop in
                      efficiency leads to a loss in revenue for the operator of
                      the biogas plant. Together with the additional equipment
                      expenditures for the CO2 separation, this loss is defined as
                      the CO2 separation costs. For a retrofit of existing biogas
                      plants with an installed electric power of 75−1000 kW, the
                      CO2 separation costs are determined to be 88−33 €/t. The
                      process shown therefore offers a promising way to deliver
                      biogenic CO2 at low cost for decentralized Power-to-Fuel
                      systems.},
