Economical and ecological evaluation of the advanced electricity production technologies adapted for carbon dioxide capture

Particularly interesting in ecological and environmental context, are two technologies: Integrated Gasification Combined Cycle (IGCC) systems and Supercritical Coal-fired Power Plant (SCPP). The main aim of the analysis was ecological and economical analysis of the selected technologies, both with and without CCS installation. The principal indicators of this evaluation was: breakeven price of electricity, unit emission and CO2 avoided cost. In the analysis the existing support mechanisms, mainly in the form of EU emission allowances trading scheme were, among other, taken in consideration. The results of the analysis show, that systems integrated with carbon capture installation can be competitive to the system without capture. Especially interesting in this light are IGCC systems. However, on the results of the analysis a lot of factors have influence, mainly fuel price, reliability of operation or auxiliary power rate. The evaluation of these parameters was qualitatively and quantitatively presented in the paper.
