Talk to one of our experts for innovative solutions that address your challenges.

Fueling Clean Hydrogen Efforts in Mission-Critical Sectors

Achieving ambitious net zero goals requires significant emissions reduction efforts in hard-to-abate markets such as refining, chemical, steel and heavy-duty transport. Low-carbon hydrogen has emerged as a key lever for decarbonizing these sectors. Yet according to International Energy Agency (IEA) estimates, less than 1% of global hydrogen in 2022 was produced using low-emissions methods.

Solidifying our industry’s sustainable future will require the rapid acceleration of scalable low-carbon hydrogen solutions. John Crane is meeting this challenge with market-ready hydrogen innovations that equip our customers to achieve mission-critical decarbonization goals. These solutions are actively enabling green and blue hydrogen operations around the globe, from Australia to Canada and key markets in between.

Accelerating Progress Across the New Hydrogen Value Chain

John Crane takes a comprehensive approach to scaling the new hydrogen ecosystem. We believe it is essential to deploy all sources of low-carbon hydrogen, including hydrogen produced through renewable- or nuclear-powered electrolysis and traditional natural gas reforming technologies retrofitted with carbon capture solutions. However, production is just one link in the new hydrogen value chain; to decarbonize hard-to-abate sectors, hydrogen transport and storage are just as critical. We are investing heavily in technologies that enable a safe, scalable hydrogen transport infrastructure, including alternative energy carriers such as ammonia.

As John Crane enters its 107th year, we are committed to developing the solutions that shape our industry’s next century. This includes the hydrogen sealing and filtration technologies of the future, leading-edge digital solutions and hydrogen-ready services that support our industry in achieving its ambitious decarbonization goals. Through collaborations with Hydrogen Europe and other hydrogen pioneers, we are actively accelerating and scaling the new hydrogen ecosystem pivotal to our industry’s future.
