A team at the University of Hong Kong has developed a new “super steel” that can survive the harsh conditions needed to make green hydrogen from seawater. The material uses an unexpected double-protection mechanism that resists corrosion far better than conventional stainless steel. Even more impressive, it could replace costly titanium parts used in today’s hydrogen systems.
If you’re aware of electrocorrosion issues in salty electrolytes and ever looked into platinated titanium electrodes it is a very neat result. Hydrogen directly from seawater in a cheap stable cell is huge.
