PhD Studentship: Drive Innovation in Hydrogen Technology

Passionate about renewable energy and engineering? Want to tackle sustainable hydrogen challenges? The University of Sheffield’s Leonardo Centre, a global leader in tribology, invites a motivated, curious individual to join an exciting PhD. This opportunity is generously funded by John Crane Ltd, a world-renowned engineering technology leader.

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.

Project Overview

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. The project’s focus is to:

• 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.

What We Offer

• Full 4-year Funding for UK applicants: Includes UK-only tuition fees and a stipend at standard EPSRC rates (2025/2026: Bursary/Stipend: £19,795, Fees: £4,925). Please note that non-UK/EU students must cover additional fees from their own funds.
• Stipend top-up: An additional industrial top-up to the stipend is available for the right candidate.
• World-Class Research Environment: Be part of a vibrant and supportive research group with access to state-of-the-art facilities.
• Close Industry Collaboration: Gain invaluable industry insights working directly with John Crane engineers.
• Skill Development: Expand your expertise in tribology, advanced mechanical systems, and sustainable energy solutions.
• Start date: Flexible.

Who Are We Looking For?

We seek a proactive and enthusiastic individual with a first-class or upper second-class honours degree (or equivalent) in:

• Engineering (Mechanical, Materials, or related disciplines)
• Physics, Chemistry, or Applied Mathematics
