A research team at the Korea Institute of Materials Science has developed a non-precious metal-based hydrogen evolution catalyst for direct electrolysis using waste alkaline water. This breakthrough allows clean hydrogen production from industrial waste water, reducing costs and environmental impact. The catalyst, based on nickel and cerium oxide, demonstrated high efficiency and durability in a commercial-scale electrolysis system. By utilizing anion exchange membranes and a novel catalyst, the team overcame impurity interference, enhancing hydrogen production. The technology eliminates the need for complex purification processes, making hydrogen production more sustainable and cost-effective. With this advancement, the team aims to promote self-sufficiency in clean hydrogen production and expand markets for renewable energy. Dr. Sung Mook Choi highlighted the potential of this technology to transform the future of hydrogen production, emphasizing its environmental benefits and cost-efficiency. This innovative approach not only improves the sustainability of hydrogen production but also opens new possibilities for utilizing diverse water sources, such as seawater, in electrolysis. Supported by Korean government grants, this research underscores the importance of materials science in advancing clean energy technologies. Published in Advanced Science, this research showcases South Korea's commitment to sustainable hydrogen production and environmental stewardship.
