For decades, researchers around the world have searched for alternatives to iridium, an extremely rare, incredibly expensive metal used in the production of clean hydrogen fuels.



Summary

For decades, scientists have sought replacements for iridium, a scarce and costly metal crucial for producing clean hydrogen fuels. Iridium acts as a catalyst in water electrolysis, but its rarity hinders large-scale hydrogen production. Researchers are exploring cheaper, more abundant materials like ruthenium oxides, perovskites, and metal alloys to replicate iridium’s catalytic properties. The goal is to find a cost-effective and scalable solution to unlock the potential of clean hydrogen energy without relying on limited iridium reserves. Success in this endeavor is critical for the widespread adoption of sustainable hydrogen fuel technologies.
