One of the most promising technologies for capture of CO_2 from power generation plants based on fossil fuels is Integrated Gasification Combined Cycle (IGCC). This paper summarises the results of a study carried out by Foster Wheeler for the IEA Greenhouse Gas R&D Programme (IEA GHG). The study assesses the performance and costs of coal based IGCC with and without CO_2 capture, based on current technology, and the potential for improvements between now and 2020. The sensitivities to a variety of potentially significant parameters are assessed, to determine the way forward for IGCC with CO_2 capture, including the type of gasifier, the gasifier operating pressure, the type of CO-shift converter and co-separation of H_2S and CO_2.
