Researchers from the Korea Institute of Energy Research have developed a groundbreaking nickel-cobalt composite catalyst that enhances turquoise hydrogen production efficiency. This innovation allows hydrogen to be produced at 300°C lower temperatures compared to traditional methods, increasing productivity by 50%. The process also yields carbon nanotubes as a valuable byproduct, contributing to various sectors like solar cells and batteries. Turquoise hydrogen is a cleaner alternative to gray hydrogen as it produces hydrogen and solid carbon without emitting carbon dioxide. South Korea's focus on sustainable hydrogen production aligns with global carbon neutrality goals. The new catalyst, composed of 8% nickel and 2% cobalt, demonstrates over 50% greater hydrogen productivity and a longer active phase lasting approximately 150 minutes, making it suitable for industrial applications. Dr. Kim's emphasis on economic efficiency and productivity through simultaneous hydrogen and carbon nanotube production signifies a milestone in sustainable energy systems development. This research signifies a significant step toward achieving cleaner hydrogen production methods, supporting South Korea's clean energy goals and contributing to a sustainable future.
