CCS (carbon capture and storage) investment possibility in South East Europe : A case study for Croatia

In order to reduce carbon emissions, great efforts are required to optimise the processes and solve the main technical and economic problems which currently limit a large-scale diffusion of CCS (carbon capture and storage) technologies. In this paper, the main results of a techno-economic comparison between USCPC or USC plants (ultra supercritical pulverised coal combustion) with and without CCS are presented. In this study, a few related questions about the development of CCS and power generation technologies in SEE (South East Europe) are answered. The main questions considered are: (1) what are the current cost estimates for building a new entrant power plant with an installed CCS system compared to a typical USC power plant (2) what is the breakeven carbon- dioxide price to justify CCS investment for USCPC power plants. To answer these questions, a LCOE (levelised cost of electricity) model is built for the power plants in study, with assumptions best representing the current costs and technologies in the EU (European Union). Then, a sensitivity analysis of some of the key parameters of the LCOE to reveal their impact on the financial viability of the project is done. The technical model of the plant is implemented in the database of the SEE REM (South East Europe Regional Electricity Market) in order to evaluate its performance on the electricity market and results gained are analysed.
