Development of novel engineering solutions for explosion free in any fire self-venting (TPRD-less) composite hydrogen storage tanks

Summary

This PhD project aims to develop scientifically robust safety strategies and engineering solutions to bridge key knowledge gaps in the safety of compressed gaseous hydrogen (CGH2) storage tanks reinforced with polymer composites. It will focus on fire safety, particularly exploring the polymers for self-venting tanks and examining their behaviour under various fire scenarios. The limitations of current fire testing protocols should be addressed by development of new comprehensive fire test series for GTR#13 and 3D CFD design(s). The ultimate aim is to design and simulate composite self-venting tanks capable of withstanding extreme fire scenarios, such as jet fire exposure, without rupturing.

Beyond fire safety, the project aims to develop faster, safer refuelling protocols to meet the demand for efficient hydrogen refuelling processes. Selecting polymers for the tank liner and composite will consider the temperature fluctuations encountered in defuelling and fuelling, from -40°C to 85°C. The research will assess environmental factors, exploring materials that facilitate recycling, such as reduced carbon fibres and matrices that are easier to separate.

Expected outcomes include optimised tank designs using thermoset and thermoplastic matrices, adaptable to a range of applications, a globally applicable fire testing protocol, practical tank performance demonstrations under realistic fire conditions, and more efficient refuelling times for hydrogen storage systems. The project will also consider permeation, buckling, and controlled hydrogen release across the tank surface when exposed to fire.

The successful candidate will have a solid foundation in disciplines such as mathematics, physics, chemistry, fluid dynamics, heat and mass transfer, or combustion, with experience in theoretical analysis or numerical simulations. Research will be conducted at the HySAFER Centre, using cutting-edge computational tools such as ANSYS Fluent, FieldView, LSDYNA, etc. on high-performance workstations and HPC facilities. Results will be presented at international conferences and published in peer-reviewed journals.

Essential criteria

Applicants should hold, or expect to obtain, a First or Upper Second Class Honours Degree in a subject relevant to the proposed area of study.

We may also consider applications from those who hold equivalent qualifications, for example, a Lower Second Class Honours Degree plus a Master’s Degree with Distinction.

In exceptional circumstances, the University may consider a portfolio of evidence from applicants who have appropriate professional experience which is equivalent to the learning outcomes of an Honours degree in lieu of academic qualifications.

• Research proposal of 2000 words detailing aims, objectives, milestones and methodology of the project

Equal Opportunities

The University is an equal opportunities employer and welcomes applicants from all sections of the community, particularly from those with disabilities.

Appointment will be made on merit.

Funding and eligibility

This project is funded by:

• Department for the Economy (DfE)
• Vice Chancellor's Research Scholarship (VCRS)

Our fully funded PhD scholarships will cover tuition fees and provide a maintenance allowance of £19,237 (tbc) per annum for three years (subject to satisfactory academic performance).  A Research Training Support Grant (RTSG) of £900 per annum is also available.

These scholarships, funded via the Department for the Economy (DfE) and the Vice Chancellor’s Research Scholarships (VCRS), are open to applicants worldwide, regardless of residency or domicile.

Applicants who already hold a doctoral degree or who have been registered on a programme of research leading to the award of a doctoral degree on a full-time basis for more than one year (or part-time equivalent) are NOT eligible to apply for an award.

Due consideration should be given to financing your studies.
