After nearly 6 years of research, HKU scientists created steel that survives 1,700 mV in seawater, potentially replacing titanium parts and cutting structural material costs 40 times for green hydrogen
Green hydrogen has a costly weakness. Its equipment can depend on expensive titanium to survive harsh electrochemical conditions. Scientists at the University of Hong Kong have developed SS-H₂ stainless steel for hydrogen production. It resists severe corrosion in saltwater environments. The materia... Green hydrogen has a costly weakness. Its equipment can depend on expensive titanium to survive harsh electrochemical conditions. Scientists at the University of Hong Kong have developed SS-H₂ stainless steel for hydrogen production. It resists severe corrosion in saltwater environments. The material uses two protective surface layers. Researchers say it could cut structural material costs by about 40
