Over time, the water shortage crisis will have irreparable effects on the lives of many organisms, including humans. As a small contribution to alleviate the problem, the present work presents an innovative cogeneration system based on solar and wind renewable energies for sustainable production of freshwater, power, and wastewater treatment. To produce freshwater and treat wastewater in this system, the integration of a Microbial Desalination Cell with a Humidification-Dehumidification and Reverse Osmosis water desalination unit has been used. These systems obtain the required heat from solar energy to produce freshwater, and when solar radiation is unable to provide this heat, a hydrogen internal combustion engine driven with wind energy is used. Excess heat from the internal combustion engine is fed into the organic Rankine cycle with the working fluid R141B to generate power, to reduce the system waste heat and to increase the efficiency. To check the performance of the proposed system, energy, exergy, exergeoeconomic, and exergoenvironmental (4E) analyses have been carried out. The results of the analysis of the integrated system show that this system can produce 720 kW of electricity and 5.36 m 3 /h of freshwater. The energy efficiency of the system is 22.09%, and its overall cost rate and overall environmental impact rate are 540.33 $/h and 17.37 Pts/h, respectively.

“…observed the positive impact of using renewable energy sources on reducing the economic costs of energy production. Khani et al [15]. demonstrated a multi-technology solar-based energy production system, which integrates gas and steam turbine cycles, organic Rankine cycle (ORC), and carbon dioxide capture, Humidification-dehumidification (HDH), showing that electricity production can be increased from 37.3% (in winter) to 59.41% (in summer) by integrating solar energy.…”

Global warming has increased the use of renewable energy in energy systems. In this regard, the present work presents an innovative polygeneration system to produce power, ammonia, and process steam using solar, biomass, wind, and geothermal energies. By using a solar-syngas hybrid boiler, steam has been created in two high-pressure (HP) and low-pressure (LP) levels, and the HP steam is used for the gasification process. Syngas produced from biomass gasification process produces ammonia with the nitrogen obtained from an air separation unit by going through water gas shifting and carbon capture processes. Power consumption in the mentioned sections is produced by wind turbines. A Brayton cycle with ammonia and hydrogen hybrid fuel has been used to produce power and heat. The integration of supercritical CO2 and organic Rankine cycles with the hot flue gas output from the Brayton cycle has reduced heat losses and increased power generation. The presented renewable system has been analysed from the point of view of energy, exergy, exergeoeconomic, and exergoenvironmental (4E) methods. The overall results indicate that the total energy and exergy efficiencies are 31.33% and 38.53%, respectively. Also, the cost rate and environmental impacts of the whole system are calculated as 3222.35 $/h and 53.16 Pts/h, respectively. Meanwhile, the levelized cost and environmental impacts of electricity are equal to 0.18 $/kWh and 0.003 Pts/kWh, and the presented system is capable of producing 297.86 ton/day of ammonia.
