The goal of this integrated system is to reduce power consumption associated with the work of compression and hence augment power plant performance. The proposed system is compared with a conventional evaporative intercooled recuperated gas turbine (EIc-RGT). Both energetic and exergetic performance of the systems were carried out. A range of sustainability indexes were evaluated for each component of both configurations. The sustainability index helps to identify the impact on the environment. A novel entropy generation number, a dimensionless number, was proposed to identify “the ratio of component's irreversibility to the heat supplied.” The maximum energy and exergy efficiencies for SOFC-EIc-RGT were nearly double that of the EIc-RGT. A novel performance map and emission map were plotted for power plant design engineers and researchers to analyse CO and NOx emissions with various operating parameters for EIc-RGT and SOFC-EIc-RGT. This economic analysis makes the system more reliable, which includes environmental and fuel cost rates. © 2024 The Institution of Chemical Engineerseninfo:eu-repo/semantics/closedAccessEnergyEvaporative CoolingExergy AnalysisSofcSustainability IndicatorArticle185118912042-s2.0-8518909029410.1016/j.psep.2024.03.040N/A
