Dr. Woohyun Kim's team at the Korea Institute of Energy Research has made significant strides in the development of a nickel-cobalt composite catalyst for turquoise hydrogen production. Turquoise hydrogen, a clean energy technology, decomposes methane to produce hydrogen and solid carbon without emitting carbon dioxide. This innovation aligns with Korea's ambitious plan to supply 28 million tons of clean hydrogen domestically by 2050. The new catalyst overcomes limitations of existing catalysts by enabling efficient hydrogen production at lower temperatures. It achieved over 50% higher productivity at 600°C and extended its initial activity duration by 60%. Additionally, the catalyst resulted in the formation of carbon nanotubes, indicating potential for valuable by-products. Dr. Kim highlighted the economic efficiency of this simultaneous hydrogen and carbon nanotube production, emphasizing the implications for the industry. The research's publication in a prestigious journal underscores its significance and sets the stage for further advancements in turquoise hydrogen technology.
