This study aimed to access the possibilities of reducing energy penalty by carbon capture. Process simulation was performed for the three main carbon capture technologies, namely, oxy‐fuel combustion, postcombustion, and integrated gasification combined cycle with carbon capture, by using both current and near future parameters. The results showed that the enhanced parameters of the power generation devices slightly increased the work output. Energy penalty was significantly reduced by the pressurized oxy‐fuel combustion system with a self‐pressurized process compared with the oxy‐fuel combustion at atmospheric pressure. The co‐firing of biomass and coal and the reduction of the unit heat consumption of regeneration enhanced efficiency of carbon capture systems with chemical absorbing. © 2013 American Institute of Chemical Engineers Environ Prog, 33: 993–999, 2014
