Thermodynamic analysis of a tri-generation system using SOFC and HDH desalination unit

The lack of freshwater in many countries pushes authorities to utilize desalination units. Solid Oxide Fuel Cells (SOFC) have shown promising results provide the power establish a multi-generation system using hydrogen as renewable source. In this article, better improve efficiency suggested integrated system, waste heat SOFC is recovered through application Kalina cycle and Humidification-dehumidification (HDH) unit. Liquefied Natural Gas (LNG) cold stream also utilizes (KC) cooling simultaneously. As all considered cycles Kalina, LNG stream, can produce amount electricity would be higher than grid's demand, further Reverse Osmosis (RO) unit utilized increase output proposed system. main focus study perform thermodynamic analysis tri-generation which generate power, cooling, freshwater. Results indicate that exergy energy efficiencies current when density 550 (A/ m 2 ), around 55% 60%, respectively. • Suggesting novel freshwater, electricity, cooling. Thermodynamic Having 60% 55%, Parametric considering changes SOFC's density.
