This article comprehensively analyses a novel multi-generation energy system designed to produce liquid hydrogen. The versatile plant is strategically engineered to generate electrical energy, produce liquid hydrogen, and extract fresh water. Its operational characteristics are systematically examined across a range of scenarios. The primary discovery of this study is the assessment of the entire plant's energetic efficiencies, which stand at 55.91 % and 49.19 %, resulting in a total exergy destruction rate of 14365 kW. The investigation delves into the impact of critical parameters, such as reference temperature, combustion chamber temperature, and gas turbine pressure ratio, on the overall efficiency and effectiveness of the system. The study reveals that variations in these parameters have a noticeable effect on increasing total electricity output and hydrogen generation rates, ultimately enhancing overall thermodynamic efficiencies. The findings underscore the importance of elevating the reference temperature, gas turbine pressure ratio, and combustion chamber temperature for optimizing the operational parameters and efficiency of the proposed integrated energy plant. This research provides valuable insights for guiding the optimal operation of the energy system and achieving efficiency optimization.
