Hydrogen is emerging as a powerful clean fuel to fight climate change, powering factories, vehicles, and cities without carbon emissions.
Producing hydrogen sustainably using water and renewable energy has faced a major hurdle: the high cost and scarcity of iridium.
Researchers at Rice University have developed a new catalyst that reduces iridium use in water electrolyzers by over 80% while maintaining top performance.
Their findings, published in Nature Nanotechnology, show the catalyst can operate for over 1,500 hours continuously.
No carbon emissions from hydrogen fuel.
