CO2 Mitigation Options for Retrofitting Greek Low-Quality Coal-Fired Power Plants
We consider possible application of the state-of-the-art in technological concepts of CO2 capture and sequestration to retrofitting of low-quality coal-fired power plants. The most promising options, namely the oxy-fuel combustion and the flue gases treatment by amine scrubbing, were evaluated as retrofit options for a typical modern lignite-fired power plant. Results from thermodynamic simulations of the examined cases were used to demonstrate the potential for emissions reduction and evaluate the associated power output and efficiency penalties. Furthermore, an economic assessment of electricity production cost was carried out, in relation to the application of different existing and near future technologies. The economical impact related to fuel prices and CO2 emission risks was assessed.
