%X Carbon capture and storage is one technological option for reducing CO2 emissions. The oxyfuel process is based on the combustion of fossil fuels in an oxygen-flue gas atmosphere with the subsequent concentration of CO2. The oxygen is produced by cryogenic air separation with an energy demand of 245 kWhel/tO2. The application of ceramic membranes has the potential to reduce the specific energy demand of oxygen supply with consistently high-purity oxygen.This work focuses on • determining the efficiency of an advanced oxyfuel steam power plant that can be constructed today using membranes for oxygen production, • investigating and quantifying the potential for energy optimizing the overall process by changing its flow structure, • assessing the feasibility of individual optimization options based on their investment costs under market conditions.For this work, a method developed by Forschungszentrum Jülich and patented on 25 April 2012 under EP 2214806 is used. The Oxy-Vac-Jül concept is integrated into the oxyfuel steam power plant with simple process management using standardized power plant components. The net efficiency of the base power plant is 36.6 percentage points for an oxygen separation degree of 60
