π¬ New "Super Steel" Could Cut Green Hydrogen Costs 40x β and Scientists Can't Fully Explain It
A team at Hong Kong University engineered SS-H2, a stainless steel alloy tough enough to survive the corrosive chaos of seawater electrolysis β conditions that quickly destroy ordinary steel. It could replace expensive titanium components, slashing structural material costs by roughly 40 times and making large-scale seawater-based hydrogen production genuinely competitive. The kicker: the material works through a "double-protection mechanism" that the researchers themselves say cannot yet be fully explained. Is this the materials breakthrough that finally unlocks affordable clean hydrogen?
