Scientists just synthesized ultra-stable 15-atom iridium nanoclusters that last 20 hours in air—a feat once deemed impossible. These outperform commercial catalysts by 1.5x, slashing costs for hydrogen fuel and pollution control.

15-atom clusters maintained 92% activity after 20 hours vs. 60% for commercial catalysts

Ambient-air synthesis cuts production costs by avoiding vacuum chambers

Team plans pilot tests with Toyota and BASF within 18 months

Could reduce iridium usage in electrolyzers by 30%, saving $150M/year industry-wide

At scale, these nanoclusters could drop green hydrogen production costs below $2/kg—the magic number to undercut fossil fuels.
