The Korea Institute of Energy Research has made significant strides in hydrogen production with the creation of a novel nickel-cobalt composite catalyst. This catalyst aims to accelerate the commercialization of turquoise hydrogen, a clean technique that produces hydrogen and solid carbon without emitting carbon dioxide during production. The innovative catalyst, containing 8% nickel and 2% cobalt, has demonstrated remarkable efficiency in hydrogen production, surpassing traditional catalysts and extending endurance by 60%. The research team also observed the formation of carbon nanotubes during the process, showcasing the potential for valuable by-products. This breakthrough paves the way for simultaneous hydrogen and carbon nanotube production, emphasizing productivity and economic efficiency. Future plans involve further research into mass-production technology, performance evaluations, and the enhancement of core material technology and reaction system design capabilities. With the Korean government's focus on hydrogen production and the potential applications of turquoise hydrogen, this research holds promise for advancing clean energy and sustainability efforts.
