Breakthrough in Hydrogen Catalyst
Hydrogen is emerging as a clean fuel to power factories, vehicles, and cities without carbon emissions.
Producing hydrogen sustainably has faced a hurdle due to the high cost and scarcity of iridium, a rare metal.
Researchers at Rice University have developed a new catalyst that reduces iridium use in water electrolyzers by over 80%.
This breakthrough could make green hydrogen more affordable and scalable, with the catalyst maintaining top performance for over 1,500 hours.
The team's findings were published in Nature Nanotechnology.
