The clean hydrogen economy extends beyond hydrogen itself. It also involves numerous secondary processes involving gases such as oxygen, carbon dioxide, ammonia, nitrogen and syngas. Each of these gases presents unique challenges, and John Crane stands ready with a proven track record in delivering top-notch solutions for all these applications.

Our mechanical seals and seal support systems ensure optimal performance and safety in liquid-ring or screw compressors, which are common in small-scale hydrogen or oxygen services in green hydrogen plants. With a robust portfolio of dry gas seals, gas conditioning systems, high-performance couplings and filtration solutions, John Crane also provides seamless performance for large centrifugal and turbo compressors. As plant sizes increase, dry gas seals must reliably seal more cryogenic turboexpanders, which play a critical role in hydrogen liquefaction.  John Crane’s reliable solutions are a proven match for these high-capacity compressors.
