Gas turbine cycles (GTC), internal combustion engines (ICE), and solid oxide fuel cells (SOFC) are three important sources of waste energy, although some studies have been done about their heat recovery (WHR) systems individually, there is a lack study comparing them to select the best solution. In present research, steam Rankine cycle, CO2 supercritical Brayton cycle (SBC), inverse (IBC), air bottoming used for WHR high-temperature exhausted gas 500 kW natural gas-fueled GTC ICE. Furthermore, organic (ORC), trilateral flash Kalina SBC utilized SOFC-gas (GT). The performance 13 proposed configurations compared through 4E (energy, exergy, exergy-economic, environmental) three-objective optimizations. Considering exergy efficiency, total cost rate, unit products as target functions, SOFC-GT-ORC system has with 64.74%, 92.51 $/h, 19.03 $/GJ. GTC-IBC ICE-IBC in respective categories.
