This study proposes and evaluates an innovative multi-generation cogeneration system that simultaneously produces electricity, cooling, freshwater, and captures CO₂, utilizing a highly efficient thermal cascade driven by chemical looping combustion (CLC). The system integrates one inverse Brayton cycle (IBC), three conventional Brayton cycles, two organic Rankine cycles (ORCs), and two steam Rankine cycles (SRCs), achieving a total power output of 2,500 kW at a methane fuel flow rate of 0.075 kg/s. Waste heat recovery enables the operation of an evaporative desalination system (EDS), producing 0.1789 kg/s of high-purity water, and an absorption refrigeration system delivering 13.68 kW of cooling. The CLC configuration inherently captures 0.2 kg/s of CO₂, contributing to integrated carbon management. Detailed thermodynamic and exergy analyses reveal energy and exergy efficiencies of 77.85% and 66.61%, respectively—figures that significantly outperform traditional cogeneration systems. Sankey diagram analysis indicates that 79.34% of the input exergy is converted into useful outputs, while 17.43% is destroyed, primarily in the CLC unit due to combustion irreversibilities. Parametric studies highlight operational trade-offs: increasing fuel flow or pressure improves power output but may reduce water and cooling yields or overall efficiency. This integrated design addresses four pressing global challenges—clean energy generation, water scarcity, climate change mitigation, and thermal comfort—within a single, compact system. The results demonstrate the system’s potential as an efficient solution for future energy infrastructure, offering enhanced resource utilization and minimal environmental impact.
