Summary

Liquified hydrogen (LH2) is the most efficient way to transport hydrogen over large distances at emerging state of hydrogen infrastructure when pipelines are not yet available to deliver hydrogen to refuelling stations and homes. This is the inherently safer way to store and distribute large amount of hydrogen at refuelling stations. The development of innovative safety strategies and engineering solutions for LH2 systems and infrastructure requires fundamental understanding of underlying physical phenomena and validated engineering models and tools for safety design.

The models and safety measures to prevent and mitigate accidents involving LH2 systems and infrastructure have to be developed. The following phenomena have to be studied yet to underpin the development of the technology: multiphase release and dispersion of LH2 in the open atmosphere and confined spaces; release and dispersion of cryogenic hydrogen; thermal hazards from low temperatures; ignition parameters and flammability limits of cryogenic hydrogen; explosion of LH2 tank in BLEVE (Boiling Liquide Expanding Vapour Explosion) regime; pressure and thermal loads from LH2 and cryogenic hydrogen combustion in confined and congested areas; etc.

The suitability of available tools for gaseous hydrogen to releases of LH2 and cryogenic hydrogen should be critically analysed. Novel analytical and numerical tools for calculation of hazard distance for LH2 and cryogenic hydrogen should be developed based on an improved understanding of the underlying physics. The developed models must be validated against experimental data that is obtained in collaboration with H2020 project PRESLHY.

This is a 4-year integrated PhD project funded via Centre for Doctoral Training in Sustainable Hydrogen (CDT SusHy). The CDT is a collaboration between the Universities of Nottingham, Loughborough, Birmingham and Ulster. The Centre has four overarching centre objectives:

1.Deliver high quality transdisciplinary training, covering fundamental science, applied engineering, and systems issues and build an appreciation of societal barriers to innovation.

2.Through innovation opportunities, build initiative and stimulate an entrepreneurial mind-set.

3.Deliver “industry ready” doctorates who have a comprehensive skill set and experiences.

4.Co-create research ideas and undertake in partnership with our stakeholders, cutting edge investigations of hydrogen-based solutions to deep decarbonisation of the energy systems.

The Centre is seeking to train at least 67 PhDs across five years of intake to achieve the mass uptake of hydrogen technologies in the UK and beyond. Further project information is available here .
