Abstract: Hybrid power plants which combine a micro gas turbine with solid oxide fuel cells, are projected to reach very high electric efficiencies. Powered by biogas, they have the potential to become an important pillar for a future CO2-neutral energy mix. However, to compensate the fluctuating energy yield of wind turbines and photovoltaic power plants, they should also provide a wide operating range. While previous numerical studies show that this is the case for natural gas powered hybrid power plants, the impact of biogas utilization on the operating range is still unknown.
