[Voiceover] Researchers from Fudan University in Shanghai have developed a breakthrough in green hydrogen production. Green hydrogen made with renewable energies like wind or solar is expensive because of the amount of power required, but also because one of the key catalysts of the process uses iridium, a scarce and expensive metal. The breakthrough involves a novel catalyst that uses less of the metal, significantly cutting costs while maintaining efficiency. [Soundbite] Zhang Bo, Professor, Department of Macromolecular Science, Fudan University： "For the same catalyst, the conventional technology would use 20 grams of iridium oxide for every square meter of the equipment, but using our new technology, every square meter needs just 3 grams." [Voiceover] The research team's findings were published in the journal Science in mid-February. [Restrictions: No access Chinese mainland]
