With decreasing underground resources and increasing carbon dioxide levels, human beings are forced to use renewable energies and new methods for power generation and CO₂ elimination. In this paper, an integrated structure is developed for generating power and liquefying CO₂ using parabolic solar collectors, solid oxide fuel cell, CO₂ power generation cycle, separation unit, and CO₂ liquefaction. This integrated structure generates 346.5 kW power, 82.2 kW heat and 158.7 kg/h liquid CO₂. The hot flow outlet of the solid oxide fuel cell is used to supply the CO₂ power generation cycle and enter the post-combustion CO₂ separation unit. The parabolic solar collectors with climatic conditions in Tehran, Iran, are used to supply the heat of integrated structure and the ammonia-water absorption refrigeration cycle is employed to supply cooling for CO₂ liquefaction. This integrated structure has a total thermal energy efficiency of 40.81% and SOFC electrical efficiency of 61.71%. Economic analysis is illustrated that the period of return and the prime cost of product are 6.26 years and 0.0855 US$/kWh, respectively. To simulate the developed integrated structure, the TRNSYS, HYSYS, and MATLAB software are used. Then, using the sensitivity analysis, the effects of fuel utilization coefficient, inlet flow temperature on gas turbine and fuel cell temperature on the performance of the integrated structure are investigated.
