The climate crisis requires ramping up usage of renewable energy sources like solar and wind, but with intermittent availability, scalable energy storage is a challenge.
Hydrogen —especially carbon-free green hydrogen—has emerged as a promising clean energy carrier and storage option for renewable energy such as solar and wind. It adds no carbon emissions to the atmosphere, but currently is costly and complex to create.
One way to produce green hydrogen is electrochemical water splitting. This process involves running electricity through water in the …
