This report presents an environmental life cycle assessment of a STAG (STeam And Gas turbine) and an ICGCC (lntegrated Coal Gasification Combined Cycle) power plant. The aim of this investigation is to determine environmental aspects of carbon dioxide removal and storage. Shortcomings of the followed procedure for life cycle assessments are pinpointed in the field of the software package, the inventory and the normalization of effect scores for classification as well as evaluation. Application of carbon dioxide removal and storage results in a considerable decrease (average 80%) of the contribution to the greenhouse effect caused by STAG or ICGCC. In contrast, the remaining environmental impacts increase, varying from about 15 to 115% for STAG and 10 to 70% for ICGCC. After normalization of effectscores the increase in fuel use per TWh electricity production appeared tobe the main factor.
