Development of polymer materials and processes for conformable, recyclable, thermoplastic hydrogen storage containers (Roto-Form)
Hydrogen (H2) is increasingly being seen as the clean energy source of the future and the development of new technologies for its transportation and storage are going to be crucial. Currently the predominant designs of hydrogen storage tanks are based around a roto-moulded polymer liner that is reinforced by filament wound carbon-fibre composite. These high-pressure storage containers are typically the ‘classical’ tubular shaped cylinder with domed ends, but there is considerable scope for innovation in both their design and the materials used in their manufacture. The exploitation of novel thermoplastic polymer materials (for both liner and filament winding) has the potential to produce fully recyclable, hydrogen gas storage tanks in the future.
The aim of this project is to develop new polymer materials and manufacturing processes to produce future recyclable, thermoplastic Type IV hydrogen storage vessels. This will be achieved by systematically developing demonstrator prototypes from a range of tailored thermoplastic polymer liners and thermoplastic polymer fibres to showcase the potential to establish this cutting-edge hydrogen gas storage technology. This has the potential to fundamentally change, significantly improve and ultimately revolutionise rotomoulding and the manufacturing practices for Type IV hydrogen tanks. However, they need to be proven as technically and commercially viable. The proposed innovative approach will combine the practical experience of the PPRC in polymer processing with the world leading polymer design capabilities of TotalEnergies. It will allow the optimisation of the properties and processing of a range of polymer liner materials (monolayer, multi-layer, foamed) and thermoplastic filament windings utilising a range of thermoplastic polymer fibres in the process, ultimately improving efficiencies and reducing cost. The work will also facilitate a study of sustainability in terms of utilising recycled polymers, optimising energy consumption and cycle time against conventional rotomoulding operations. The main objectives are:
Objective 1: Complete Process Manufacturing Material audit – Thermoplastics - Liner (PA11 / PA6 / PE / recyclate) / Thermoplastic- Fibre (PA/PE) Objective 2: Moulding of a range of monolayer, multi-layer and foamed thermoplastic materials (liner), mould heating and mould cooling - heat transfer, process optimisation Objective 3: Optimisation of the polymer liner with the thermoplastic polymer filament winding Objective 4: Analysis and testing to determine mechanical properties – impact, tensile, flexural, shrinkage, warpage, wall thickness distribution
The project is a collaboration between the multinational energy company TotalEnergies and the Rotational Moulding research team at the Polymer Processing Research Centre (PPRC) at Queen’s. TotalEnergies are one of the world’s premier polymer material developers, and this collaboration will allow the project to exploit unique material technological know-how within the research work. It is planned that part of the work will be completed in Belgium/France at Total’s global research centres.

Mechanical Engineering overview
Our society needs exceptional engineers who can understand, create and harness technology to address our shared global challenges. Without these individuals our long-term success as technologically advanced societies and economies will be diminished. Undertaking a PhD in the School of Mechanical & Aerospace Engineering will enable you to make a real difference, positively impacting your career and through your research improving engineering methods and practice, and ultimately society.
Research undertaken by PhD students in the School of Mechanical & Aerospace Engineering forms a critical part of our research portfolio. Our research portfolio is ranked 24th in the UK with 96% of our Engineering research rated as world-leading or internationally excellent [REF 2021/ Times Higher Education]. What is more the REF2021 assessment, which is carried out by panels of academics and international experts, rated over 99% of the university research environment as world-leading or internationally excellent. Within this environment our PhD students research within the broad topics of design, materials, manufacturing, and energy.
Joining us as a PhD student you will be part of a dynamic environment and will study alongside students from many countries worldwide. It is a lively community of over 100 students, in which you will have the opportunity to develop both career and life skills, for example by participating in cohort training and mentoring programmes and student led social and cultural activities.
A PhD studentship is an investment in your personal development, worth over £100,000. Many of our PhD graduates take-up academic roles, while others go on to play leading roles in industry or become entrepreneurs. A PhD provides many benefits, among others it provides a range of “transferable skills”, such as independent and critical thinking, analytical and problem solving skills, leadership, and self-confidence. Because of these developed characteristics we see that many industry leaders hold a PhD. You will likely get a higher salary after graduation from a PhD than you do three years after an undergraduate degree. More importantly, you will get a different type of job and likely make progress faster through promotion and reward mechanisms. This, of course, depends on your ambition, but a PhD builds an exceptional career foundation.
