Breakthrough catalyst could transform turquoise hydrogen production
Researchers from the Korea Institute of Energy Research, led by Dr. Woohyun Kim, have created a composite catalyst using nickel and cobalt. This innovation significantly reduces the energy required to produce turquoise hydrogen making it more sustainable and commercially viable.
Understanding turquoise hydrogen
Hydrogen, though colourless, is classified into categories based on its production methods. Green hydrogen, the cleanest form, is generated through electrolysis using renewable energy. Blue hydrogen, created through steam methane reforming, produces carbon dioxide as a byproduct that is then captured.
Turquoise hydrogen uses methane pyrolysis to split methane into hydrogen and solid carbon at lower temperatures, avoiding carbon dioxide emissions. However, the high energy demand of traditional methods has hindered its widespread adoption until now.
Game-changing catalyst technology
Dr. Kim's team has developed a nickel-cobalt catalyst that lowers the temperature needed for turquoise hydrogen production by 300°C, reducing energy consumption while boosting efficiency. This innovation has demonstrated over 50% higher hydrogen yields and extended activity duration by 60% compared to conventional nickel or iron catalysts.
Dr. Kim described the findings as a "groundbreaking outcome," and the catalyst has the potential to make turquoise hydrogen production more cost-effective, enabling governments, cities, and industries to invest in this cleaner energy source. Dr. Kim stated:
We aim to secure core material technology and optimise reaction systems to support the transition to a more sustainable hydrogen economy.
As hydrogen technology continues to evolve, breakthroughs like this catalyst pave the way for a cleaner, more energy-efficient future.
