Hydrogen gas generated using renewable energy is a promising source of clean fuel. One of the most common existing technologies for electrolysis—the process of generating hydrogen gas from water using electricity—is proton exchange membrane (PEM) electrolysis. Governments and organizations like the International Renewable Energy Agency are pushing for initiatives to make hydrogen more mainstream, but PEM electrolysis depends on the rare and expensive catalyst iridium, which has been a bottleneck for the tech’s adoption.
