In the future renewable energy systems where hydrogen is used as secondary energy carrier, bearings, seals, and valves may operate in hydrogen. It is important in ensuring reliability and safety to know any deviation of their tribological behaviors from those in normal atmosphere. It is well known that hydrogen causes embrittlement in many of commercially available steels, and the bearing steels are not the exception.
