PhD : Novel Sealing -Pressure H2 and Low-Carbon Storag

Why This PhD?

• Impact Clean Energy's Future: Develop next-generation mechanical seals for high-pressure hydrogen systems—key to renewable energy.
• Work with Industry Leaders
  :
  Collaborate with John Crane, a $1B global technology company driving sealing innovation.
• Gain Research/Industry Experience
  :
  Split your time between advanced laboratories at The University of Sheffield and John Crane’s Research Centre in Manchester and Manufacturing site in Slough.

The world is moving rapidly toward renewable energy. Hydrogen is at the forefront as a clean fuel, but its safe storage and use at high pressures require advanced, reliable technology. By joining this project, you’ll be developing innovations critical to a greener, more sustainable future. In hydrogen storage and transport, high-performance mechanical seals are essential. These seals prevent gas leakage by maintaining a sub-micron-thin layer of hydrogen between a rotating ceramic face and a stationary face.

• Conduct cutting-edge experiments to investigate how surface texture affects seal performance and explore the use of an ultrasonic sensor for real-time monitoring.
• Experiment with ultrasonic sensors for real-time seal gap measurement.
• Combine experimental research and mathematical modelling to pioneer innovative sealing solutions.
