Researchers at the University of Sharjah in the UAE have unveiled a groundbreaking technique for producing clean hydrogen directly from seawater. The innovative approach involves a multi-layered electrode system that can operate without the need for desalination processes or added chemicals. This development addresses the common issues of corrosion and performance degradation caused by chloride ions in traditional seawater electrolysis. The prototype system created by the team has demonstrated remarkable efficiency, maintaining industrial-scale hydrogen production for more than 300 hours with an impressive Faradaic efficiency rate of 98%. This high conversion rate means that almost all the electrical input is effectively transformed into hydrogen gas. The potential applications of this technology are significant, particularly in arid coastal areas like the UAE, where freshwater resources are limited but abundant seawater and sunlight are available. By utilizing this method, it becomes feasible to establish solar-powered hydrogen farms that can produce 'green hydrogen' through electrolysis powered by renewable energy sources. In contrast to 'blue hydrogen' derived from natural gas, green hydrogen offers more substantial carbon reduction benefits and aligns better with sustainable energy practices. The team is now focused on advancing to pilot-scale tests and aims to develop a modular, solar-powered hydrogen generator that can operate effectively in real-world scenarios, especially in challenging environmental conditions. The lead author of the study emphasizes the scalability and efficiency of their approach, highlighting the transformative potential of seawater electrolysis for clean hydrogen production. The technology has already attracted interest from clean energy startups and regional innovation hubs, signaling a promising future for this sustainable energy solution.
