Description: Zum Vergleich der in COORETEC betrachteten Kraftwerksprozesse (GuD-, DKW-, Oxyfuel- und Oxycoal-Prozess, IGCC mit CO2-Abtrennung, DKW mit MEA) werden einheitliche Annahmen und Randbedingungen aufgestellt und Prozessanalysen durchgeführt. Aussagen über die heute machbaren Technologien sowie deren CO2-Vermeidungspotential werden getroffen. Aufgrund der großen Unterschiede zwischen den zu betrachtenden Prozessen müssen die Anlagen- und Betriebsparameter miteinander vergleichbar gestaltet werden. Dies umfasst die Identifizierung aller Parameter und die Definition realitätsnaher, standardisierter Werte für alle Einflussgrößen. Mittels Modellierung und Simulation werden Aussagen über die heute erreichbaren Wirkungsgrade und das Wirkungsgradpotential einzelner Technologien gemacht. Wesentliches Ergebnis der Studie ist es, Aussagen zu treffen, welche Prozesse unter realitätsnahen und vergleichbaren Randbedingungen das größte technische und wirtschaftliche Potenzial besitzen, den Klimaschutz schnellstmöglich voranzutreiben. Die hierbei entwickelten standardisierten Annahmen und Randbedingungen sollen auch bei der zukünftigen Untersuchung von alternativen Prozessen Anwendung finden.

Title: Comparison of COORETEC-related power generation processes under unified realistic boundary conditions
Description: Reducing the anthropogenic Climate Change would require a global reduction in the emissions of carbon dioxide (CO2). In the case of electricity generation from fossil fuels, which constitutes the source of approx. 60Prozent of the electricity produced worldwide, this effort focusses in increasing efficiency, changing the fuel mix or separating downstream the CO2 produced. In the framework of the Research Programme COORETEC (CO2-REduction-TEChnologies) the most promising technologies for fossil-fuelled power plants were investigated, according to the current status of knowledge. In the COORETEC-Study 'Forschungs- und Entwicklungskonzept für emissionsarme fossil befeuerte Kraftwerke' (Research and Development Concept for fossil-fuelled Power Plants with reduced Emissions) the coefficient of electrical efficiency, for example, differ widely from one process to the other. Furthermore some calculations are based on boundary conditions and assumptions which sometimes render the resulting coefficients of efficiency, their comparison but also the technical feasibility of the whole process doubtful. The present research project focused on the key processes investigated currently in the COORETEC Programme (cf. below) and aimed at creating a reliable Database for reliable estimation of the process efficiencies under realistic operating conditions. Without CO2 Separation - Steam Process - Steam Power Plant (Hard Coal/Lignite fuelled) - Combined Process - Gas/Steam Plant. With CO2 Separation - Steam Process - Steam power plant with downstream separation - Oxyfuel process with flue gas recirculation and cryogenic Air Separation Unit or high-temperature membrane to supply the combustion oxygen - Combined Process - Integrated Gasification Combined Cycle with CO2 separation. By using the process data in a consistent way, so that all comparable components are described using comparable parameters, ensures that the obtained efficiency coefficients and the potential reductions in CO2 are rendered directly comparable. After describing the current state of the art in each particular technology, various scenaria for the future development of the efficiency potentials were determined and compared. Through consistent parameterisation it was possible to evaluate and compare the relevance and importance of the various developments envisaged in each specific process. Key deliverable out of this research project was to yield a conclusion on which one of the processes being studied in COORETEC shows the highest potential under technical and economical viewpoint, when developed under realistic and practically-relevant conditions, to efficiently contribute to Climate protection.
