Technologies for Gas Turbine Power Generation with CO2 Mitigation (GTCO2)
Conceptual superstructure for future gas turbine power plants with CO2 mitigation.
Scope of project
The world primary energy demand is expected to double by 2050. It is assumed that this increased
demand cannot be solely covered by renewable energy sources (such as hydro, wind, or solar), or by
nuclear energy. Thus, an increased number of fossil-fuel-powered gas turbine systems for electricity
generation will be implemented in the coming decades.
The current project addresses specifically the challenge of developing a gas turbine with reduced CO2
emission. Advanced technologies in various fields (fuel conversion, membrane systems, enhanced heat management) will impact future gas
turbine concepts. Thermo-economic process modeling will be applied to select promising technology
pathways toward a zero emissions, fossil-fuel powered gas turbine. The overall goal is a commercially
viable process for mitigation of CO2
at a cost of <20 €/ton CO2
avoided. The modeling effort will
establish quantitative targets for process components (e.g. sequential combustor, turbomachinery
and membrane-based air separation).
