Parabolic trough solar collectors a two stages Rankine cycle two organic Rankine cycles two absorption cooling systems a gas turbine system a once-through (OT) multi stage flash (MSF) desalination unit a geothermal unit a heat pump an electrolyser and a thermal energy storage are used as sub-systems. The novelty of the system is to focus on novel sub-system design pattern for the proposed multi-generation system by using multiple energy inputs as there is a gap about those studies in the literature. The overall system performance is evaluated from energetic exergetic exergo-economic environmental (4E) and sustainability points of view by using the EES software package. The total installed power and hydrogen mass flow rates are 7.76 MW and 3.52 kg/h respectively. The energy and exergy efficiency values of the overall system are found to be 65.55% and 27.09%. Fresh water flow rate is calculated to be 6.16 kg/s with 10 stages. The overall unit product cost is determined to be 2179 $/GJ and the overall social ecologic factor is calculated to be 1.37.Englishinfo:eu-repo/semantics/closedAccessMulti-generation, Exergo-economics, Renewable energy, Hydrogen, DesalinationPERFORMANCE ASSESSMENT, INTEGRATED-SYSTEM, OPTIMIZATION, DRIVEN, DESALINATION, ELECTRICITY, GENERATION, PEMRenewable EnergyDesalinationHydrogenExergo-economicsMulti-generationArticle
