Funded PhD Opportunity New generation of inherently safer composite tanks for hydrogen storage
This opportunity is now closed.
The inherently safer fuelling of a hydrogen storage container is a challenging problem. Independent on a container design the regulation requires: temperature inside doesn’t exceed 85 C, pressure does not exceed 1.25 of Nominal Working Pressure, i.e. 87.5 MPa for 70 MPa onboard storage tanks, and the State of Charge does not exceed 100%. The consumer expectations include the fuelling time within 3 min (longer for busses). The problem of fuelling control is complicated by changing pressure and temperature inside the tank and at inlet, conjugate heat transfer from/to hydrogen through a piping system and a tank wall to/from the ambience, etc.
One aim of this doctoral study is development and validation of CFD (Computational Fluid Dynamics) and reduced models for better understanding and reproduction of underlying physical phenomena of hydrogen tank fuelling (both onboard and stationary). The models should be used for prediction of thermal behaviour of different systems “hydrogen storage at refuelling site – piping system – dispenser – hydrogen storage tank – atmosphere” during fuelling.
The results of research will be used for the establishment of inherently safer and automated hydrogen fuelling protocol for light- and heavy-duty vehicles. Compressed gas energy storage technologies are widely used in different areas of our life. Compressed Natural Gas (CNG), Liquified Petroleum Gas (LPG), Compressed Gaseous Hydrogen (CGH2) vehicles and buses are hitting the roads. Safety is of paramount importance for compressed gas storage systems and infrastructure.
The main unresolved issue facing the compressed gas energy storage sector is a catastrophic rupture of lightweight composite pressure vessel (CPV) in a fire. Fire resistance rating (FRR) of today’s CPV, i.e. time in a fire before rupture, is only 3-12 min. Catastrophic rupture of CPV in a fire is a serious threat to life and property.
This project aims to further develop and validate the breakthrough leak-no-burst (LNB) safety technology for prevention of CPV catastrophic rupture in a fire, and thus eliminate hazards and associated risks from disastrous blast wave, fireball, and projectiles (Ulster’s IP “Composite Pressure Vessel for Hydrogen Storage”, 14.02.17).
This research is strongly linked from the beginning with industry, both directly and through standard development organisations (ISO, CEN) and regulators (UN GTR#13 IWG SGS). The aim will be achieved through: performing hazard/risk analysis; case studies analysis; accident scenarios development; measuring material properties; model development; validation tests; recommendations for the update of Regulations, Codes and Standards.
