Corumlu V.Ozturk M.2024-07-222024-07-2220210363907Xhttp://akademikarsiv.cbu.edu.tr:4000/handle/123456789/13151This paper proposes the design of a new solar power-based multigeneration system for generating hydrogen, ammonia, methane, and other beneficial outputs. This combined plant consists of the solar plant, Rankine cycle, organic Rankine cycle, single-effect absorption with ejector, carbon dioxide capture, hydrogen, ammonia, methane, drying, hot, and freshwater generation plants. The overall plant is investigated utilizing the Engineering Equation Solver software. The energy and exergy efficiencies of the integrated plant are computed as 0.6689 and 0.6227. In addition, the largest exergy destructions in the system are 6924 and 4037 kW, which occur at the Rankine cycle and solar power cycle, respectively. Moreover, the thermodynamic performance of the combined plant is investigated through parametric works and the impacts of plant working conditions on the plant efficiencies are evaluated. © 2021 John Wiley & Sons Ltd.EnglishAll Open Access; Gold Open AccessAlternative fuelsAmmoniaCarbon dioxideExergyHydrogenMethaneRankine cycleSolar energySolar power plantsCarbon dioxide captureEnergy and exergy efficiencyEngineering equation solversExergy destructionsIntegrated plantsOrganic Rankine cyclesPerformance analysisThermodynamic performanceSolar power generationArticle10.1002/er.7019
