Abstract
The current study introduces a ground-breaking multi-generation plant utilizing solar and wind energy. This study proposes a hybrid system that combines wind and a steam Rankine cycle for power generation. This integrated system aims to address cooling needs through a dual-effect cooling system and heating requirements through a steam Rankine cycle heat exchanger. Additionally, the system intends to produce hydrogen through a proton exchange membrane electrolyzer and ammonia via a reactor. This comprehensive approach investigates the potential for a more versatile and efficient plant design. This innovative system goes beyond electricity generation, offering a comprehensive solution for power (44.8 MW), heating (20.64 MW), cooling (123.9 MW), hydrogen (263.1 kg/h), and ammonia (106.48 kg/h) production. A thermo-economic-environmental analysis reveals promising performance with high energetic (83.65%) and exergetic (17.97%) efficiencies, an exergo-environmental impact factor (0.91) as well as a total product cost rate of $1.44/s. The parabolic trough solar collector optimization is crucial as it contributes to the majority (57%) of exergy destruction. Amongst investigated parameters, an ambient temperature of 35°C yields the best exergo-environmental performance.
