Developing carbon capture strategies is essential to prevent global warming. In this study, detailed introduction of conventional oxy-coal power plants is presented. New generation oxy-coal systems such as MILD oxy-combustion, SPOC, ALIVE, etc. are also introduced. These technologies ensure lower energy penalty than conventional systems. Retrofitting coal power plant with new generation oxy-coal systems is suggested. As carbon capturing policies are implemented, these power plants would be profitable and have the opportunity to stop global warming.
