A technical assessment of the CO2 capture modeling for GT/SOFC/CHP hybrid cycles

In GT/SOFC/CHP hybrid systems, to achieve green production, CO2 capturing pattern is essential. The use of CO2 capture system reduces emissions, but it reduces the total efficiency as a disadvantage. The aim of this study is to select the best technology as a goal for maximizing CO2 capturing with the minimum achievable energy penalty. In this research, by using an analytical approach, a novel categorization of CO2 capture technologies in GT/SOFC/CHP systems is presented. Six categories of various technologies are described by using Strength-Weakness (S-W) analysis. Then, with a comparative approach, an assessment in some selected cycles is conducted. By this mean, their modelling targets, type of CO2 capture systems, and technical and performance specifications are evaluated. By using this analysis, current areas of research, international research orientation and potential future research areas are identified. The results show that oxy-anode combustion technology is the best CO2 capture technology for GT/SOFC/CHP systems with respect to all research factors and the current feasibilities
