Project Goals 1)technical and economical assessment of CCS technologies (based on post- a pre-combustion) integration into IGCC power plant in Czech Republic IGCC. Considered CO2 capture technologies are: Rectisol wash(pre-combustion) Polymeric membranes(pre-combustion) Cryogenic/Low temperature capture(pre-combustion) Ca-Looping (post-combustion) 2)technical and economical study of captured CO2 transport (gas/liquid) to storage in Czech Republic (on-shore) and in North sea (off-shore) transprotu 3)comparison with results from FR-TI/379 project which analysed the integration of oxyfuel and post combustion (ammonia scrubbing) CCS technologies into 250 MWe coal power plant with subcritical parameters in Czech Republic

new power plant location: Power plant Prunerov II. area power plant design output => 250 MWe czech lignite focus on using of proven technologies (gasification, gas turbine etc.), except for CO 2 separation technologies. power plant (based case) is based on similar realizations in the world and according to the recommendations derived from the operational experience of IGCC Vresova power plant Input data for design case

Models

Steam cycle models for Ca-looping (CVUT x SINTEF) complete all rest models (the end of June 2016) determine the number of cases for optimization (this meeting) first economic results for pre-combustion base cases (the end of May 2016) determine the work schedule for the next two months.
