Part A: Review and selection of promising conversion and capture technologies * ´ Kay Damen , Martijn van Troost, Andre Faaij, Wim Turkenburg Department of Science, Technology and Society, Copernicus Institute for Sustainable Development and Innovation, Utrecht University, 3584 CS Utrecht, The Netherlands Received 4 February 2005; accepted 30 November 2005 Available online 20 January 2006 Abstract We performed a consistent comparison of state-of-the-art and advanced electricity and hydrogen production technologies with CO2 capture using coal and natural gas, inspired by the large number of studies, of which the results can in fact not be compared due to specific assumptions made. After literature review, a standardisation and selection exercise has been performed to get figures on conversion efficiency, energy production costs and CO2 avoidance costs of different technologies, the main parameters for comparison. On the short term, electricity can be produced with 85–90% CO2 capture by means of NGCC and PC with chemical absorption and IGCC with physical absorption at 4.7–6.9 Vct/kWh, assuming a coal and natural gas price of 1.7 and 4.7 V/GJ. CO2 avoidance costs are between 15 and 50 V/t CO2 for IGCC and NGCC, respectively. On the longer term, both improvements in existing conversion and capture technologies ar
