Renewable energy-supported multigeneration plants and energy storage systems have important in reducing carbon emissions and also effective use of energy sources. In this study, both a renewable energy source-based energy storage process and a newly developed multigeneration plant are studied through detailed thermodynamic analysis. Here, the energy required for the compressed air storage unit is obtained from the hybrid system of solar and wind energy, and the stored compressed air reacts with natural gas in the Brayton cycle and goes to the multigeneration cycle. Furthermore, the key aim of this research is the examination of a multigeneration system for power, heating, cooling, hot water, and hydrogen generation using energy and exergy efficiency methods. The investigated model includes a thermoelectric generator, an organic Rankine cycle, a hydrogen production and liquefaction unit, a cooling system with an ejector, a Brayton cycle, a Rankine cycle with three turbines, and a compressed air energy storage unit with solar photovoltaic and wind turbines. Moreover, to observe the impact of some substantial design variables on the proposed subsystems and the entire plant's performance and irreversibility rate, thermodynamic analysis is applied parametrically. In light of assessment findings, the net power generation rate of the entire system is 31,308 kW at 25 °C reference condition. Also, the net hydrogen generation capacity, cooling capacity, and heating capacity of the total plant are 0.0499 kg/s, 3650 kW, and 4281 kW. In conclusion, the energetic and exergetic efficiencies of the entire model are determined as 0.5258 and 0.4867.
