Scientists at the University of Hong Kong developed a special stainless steel that can withstand harsh conditions and produce green hydrogen. This breakthrough could make clean energy more affordable.

Green hydrogen is an important step towards a sustainable future. To produce it, we need strong and durable materials that can handle seawater and other harsh environments. A team led by Professor Mingxin Huang at the University of Hong Kong has made a significant discovery in this area. They created a special stainless steel called SS-H2 that resists corrosion even under extreme conditions.

This new material is crucial for large-scale clean energy production. Currently, electrolyzers are expensive and prone to damage from seawater. The HKU team's breakthrough could reduce the cost of structural materials by 40 times. This would make green hydrogen more affordable and accessible.

The secret to SS-H2 lies in its unique properties. Unlike ordinary stainless steel, it forms a second protective layer on top of the usual chromium oxide barrier. This additional shield helps protect the steel from damage up to an ultra-high potential of 1700 mV.

This research builds upon Professor Huang's long-running 'Super Steel' project, which has already produced anti-COVID-19 stainless steel and ultra-strong and ultra-tough Super Steel.
