Carbon Tax vs. CO2 Sequestration Effects on Environomic Analysis of Existing Power Plants

The environomic analyses and optimization of three existing plants—steam cycle (320 MW), combined cycle (350 MW) and cogeneration gas turbine cycle (30 MW)—are here presented. The effects of the abatement devices of NOx and SOx emissions on the cost of electricity are evaluated. The effects of carbon dioxide emissions are also considered from two different points of view: CO2 sequestration and CO2 taxation (carbon tax).
