Description: Das Projekt "Innovative CO2-Abtrennung" wird vom Umweltbundesamt gefördert und von Technische Universität Hamburg-Harburg, Institut für Energietechnik M-5 durchgeführt. A main bottleneck in post-combustion CO2 capture causing significant reduction in power plant efficiency and preventing cost effectiveness is the low flue gas CO2 partial pressure, limiting membrane flux, solvent selection and capacity. In pre-combustion CO2 capture instead, key bottlenecks are the number of processing steps, the possible low hydrogen pressure and the high hydrogen fraction in the fuel. Global deployment of CO2 capture is restrained by a general need for prior removal of SO2. iCap seeks to remove these barriers by developing new technologies with potential for reducing the current energy penalty to 4-5Prozent points in power plant efficiency, to combine SO2 and CO2 removal and thus reduce the avoidance cost down to 15 €/tonne CO2. iCap will develop solvents forming CO2 hydrates or two liquid phases enabling drastically increased liquid phase CO2 capacity, radically decreasing solvent circulation rates, introducing a new regime in desorption energy requirement and allowing CO2 desorption at elevated pressures. Furthermore, it will develop combined SO2 and CO2 capture systems increasing dramatically the potential for large scale deployment of CCS in the BRIC countries and for retrofitting in Europe. It will also develop high permeability/high selectivity low temperature polymer membranes, by designing ultra-thin composite membranes from a polymeric matrix containing ceramic nano-particles. Another target is to develop mixed proton-electron conducting dense ceramic-based H2 membranes offering the combined advantages of theoretically infinite selectivity, high mechanical strength and good stability. On the basis of these developments novel coal and gas-based power cycles will be evaluated that allow post-combustion CO2 capture at elevated pressures, thus reducing the separation costs radically. These technologies will integrate improved separation technologies into brownfield and greenfield power plants and will yield novel power cycles, in order to meet the performance and cost targets of the project. In carrying out its research in iCap the Institute of Energy Systems has also undertaken the leadership of Work Package 5: Technology evaluation, cost and efficiency estimations.
