Assessment and mitigation of Hydrogen fuelled vehicle hazards

Lead Research Organisation: University of Ulster
Department Name: Sch of Built Environment


Hydrogen Safety Engineering and Research Centre (HySAFER) at Ulster University is one of the key providers of high-quality hydrogen safety research, engineering and education globally. Main area of HySAFER research is development of models for hydrogen safety engineering.
This PhD research project will focus on closing knowledge gaps and addressing technological bottlenecks associated with safety of high-pressure hydrogen storage relevant to hydrogen-fuelled transport. HySAFER team draws on practical engineering needs from its collaboration in prestigious UK and European industry-driven research projects. Areas where novel engineering models are required include, but not limited to:
predicting thermal condition of tank structure across a wide range of tank volumes (car, LGV, HGV), tank construction materials (different composites, liners, thermal protection solutions), tank off-design conditions (fire, blowdown), etc.
safe fuelling and defueling of modelling onboard tanks fuelling and defueling, which is of particular interest to OEMs in safety context,
time to prevention of tank rupture in a fire due to pressure valve failure,
simulation of fireball size and fireball thermal hazards from tank rupture in a fire, both in open space and accounting vehicle structure;
modelling of blast wave propagation and assessment of pressure hazards associated with high-pressure tank rupture in tunnels and confined enclosures;
thermal and pressure hazards of ignited jet fires associated with releases from pressure relieve valve.
The suitable candidate should have background in physics, including fundamental heat and mass transfer, combustion, etc. The research will include analysis of relevant physical phenomena, review of existing state-of-the-art, development of novel physical model(s) based on fundamental principles, model implementation, identification of experimental data for validation of simulations and validation campaign. It is envisaged that this PhD research project will contribute to development of innovative prevention and mitigation strategies and engineering solutions for hydrogen systems and infrastructure. Research results are expected to be presented in peer-reviewed journal publications and conference contributions.
HySAFER is the major contributor of models to EU funded free access online e-Laboratory of Hydrogen Safety ( The candidate will join HySAFER team involved in leading-edge research and delivering externally funded projects. It is expected that the new models will be implemented using existing protocol and programming convention of mentioned above e-Laboratory of Hydrogen Safety. Knowledge of popular web frameworks, programming languages and technologies for Front-end and Back-end is desirable e.g. Python, C++, Django, PHP, Java and JavaScript etc. Exposure to numerical modelling techniques is welcome as the candidate could use contemporary tools like CFD for verification of reduced models for online laboratory.
