Abstract
In this study, a detailed thermodynamic and CO₂ emission analysis was carried out for an integrated biomass-fueled tri-generation system that simultaneously produces electricity, desalinated water, and cooling. The main novelty of the new proposed configuration lies in its combined use of urban solid waste as fuel to generate three useful energy outputs, improving overall efficiency and reducing CO₂ emissions compared with previous studies. According to the baseline simulation, the system can generate 4,994 kW of net electrical power, 1,034 kW of cooling, and 11,960 kg/h of desalinated water with a 33.28% recovery rate. The overall energy and electrical efficiencies are 73.82 and 39.92%, respectively, with a CO₂ footprint of only 0.2 kg CO₂/kWh. Parametric analyses indicate that optimizing the gas turbine inlet temperature and the Organic Rankine Cycle pressure further enhances performance. Overall, the system offers a sustainable and practical solution for coastal, island, and small industrial or residential applications.
