Thermodynamic and Environmental Performance Analysis of the Marib Integrated Power and Cooling Cycle

Meeting energy demands while ensuring sustainability is a critical challenge in underdeveloped regions like Yemen. The Marib Integrated Power and Cooling Cycle (MIPCC) is proposed as an innovative solution to enhance power generation efficiency and reduce environmental impact by utilizing waste heat from the Marib gas turbine plant. This study evaluates the thermodynamic, economic, and environmental performance of the MIPCC system, which integrates the Brayton, Rankine, and absorption refrigeration cycles for simultaneous power generation and cooling. The results indicate that the MIPCC system significantly improves performance, achieving a net power output of 226 MW with energy and exergy efficiencies of 47.91% and 46.26%, respectively. The system reduces CO₂ emissions to 403.5 kg/MWh and minimizes the cost of electricity to 70.55 $/MWh, demonstrating both environmental and economic viability. Additionally, it provides a cooling capacity of 53.5 MW, making it ideal for hot climates. The MIPCC offers a transformative energy solution by maximizing efficiency, lowering emissions, and reducing dependency on fossil fuels. Its application in energy-deprived areas can enhance energy security and economic growth, making it a scalable model for sustainable power generation in regions facing infrastructure and energy challenges.
