A breakthrough in hydrogen production has been achieved by a Japanese research team, reducing the need for iridium by 95% without compromising efficiency, paving the way for sustainable, large-scale hydrogen energy solutions.
As the world is transitioning from a fossil fuel-based energy economy, many are betting on hydrogen to become the dominant energy currency. But producing “green” hydrogen without using fossil fuels is not yet possible on the scale we need because it requires iridium, a metal that is extremely rare.
In a study published today (May 9) in the journal Science, researchers led by Ryuhei Nakamura at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan report a new method that reduces the amount of iridium needed for the reaction by 95%, without altering the rate of hydrogen production. This breakthrough could revolutionize our ability to produce ecologically friendly hydrogen and help usher in a carbon-neutral hydrogen economy.
