Hormozgan Province, as one of the most energy-intensive regions in Iran, faces significant challenges in ensuring the sustainable supply of electricity an‎d freshwater. This study aims to design an integrated hybrid renewable energy system for the Soru region of Ban‎dar Abbas to simultaneously provide electricity, desalinated water, cooling, heating, an‎d domestic hot water for a 500-household township. The proposed system utilizes solar, wind, geothermal, an‎d microalgae-based biomass energy sources through an innovative technological integration approach. In this configuration, microalgae cultivation ponds harness wave an‎d photovoltaic energy to capture carbon dioxide emissions from a molten carbonate fuel cell an‎d convert it into biomethane. Desalinated water is produced using solar-assisted thermal recovery processes. Simulation results indicate that the system can generate 570 kWh of electricity with a fuel cell efficiency of approximately 56% an‎d meet thermal deman‎ds through a 20 kWh geothermal heat pump system. Furthermore, the system is capable of producing up to 300 cubic meters of freshwater per day during the hot season an‎d achieving a reduction of approximately 1,747 tons of CO₂ emissions, alongside eliminating six major air pollutants compared to conventional fossil-fuel power plants. The economic analysis reveals a levelized cost of 2.17 USD per cubic meter of freshwater an‎d 0.06 USD per kilowatt-hour of electricity, making the system significantly more cost-effective an‎d competitive than conventional methods. Multi-objective optimization using the NSGA-II algorithm identified an optimal configuration among 57 water an‎d power subsystems, yielding an estimated annual profit of around 460,000 USD through electricity an‎d water sales, compost production, an‎d complete independence from the national natural gas grid. This research represents a substantial step toward the realization of smart, clean-energy townships, promoting reduced grid dependence an‎d enhanced economic viability of renewable energy projects through supportive policy frameworks.
