A novel hydrogen-based desalination system for a self-sustaining community

This work proposes a novel hydrogen-based desalination system to replace fossil fuelbased plants. The system has a water-hydrogen nexus framework to achieve an efficient operation, providing electricity, potable water, and green hydrogen. Through optimal planning, less operation cost is found by considering the variation in supply and demand. Results show that the system has an average efficiency of 43.3%, higher than other renewable desalination systems. Meanwhile, the lower water production cost of 0.15$/t makes it competitive compared to membrane-based systems. The system well presents the merits of the water-hydrogen nexus.
