| Abstract | The infrastructure development of hydrogen refuelling stations (HRSs) is the top challenge of the applications of hydrogen propulsion technologies on ground transportation. Dispenser reliability often affects user experience on refilling hydrogen fuel cell electric vehicles (HFCEVs).
To assess and analyse dispenser reliability, the fuelling fault conditions that cause fuelling anomalies should be categorised and analysed based on the system operating conditions, so that the correlation between fuelling system behaviours characterised by irregular data patterns and dispenser reliability can be identified.
Besides station operating conditions and physical process control in hydrogen fuelling to the HFCEVs, interfaces built on the dispenser for data communication are also important to achieve fast normal fills while fulfilling all the safety limits and process requirements. Table 1 lists and summarises all the relevant fuelling protocols and standards for the development of fuelling communication hardware and software.
Fuelling protocols J2601, J2601-2 and J2601-3 provide guidance to HRS builders and manufacturers to fulfill performance requirements and control process limits. On the other hand, J2600 provides the requirements and guidance for designing, building and testing of fuelling connection devices, such fuelling nozzles and receptacles. J2799 imparts harmonized development and implementation of the hydrogen interfaces, specifying communications hardware and software requirements. With the instructions and recommendations of these standards, HRS infrastructure development encompassing various process control components is executed from blueprints to stations in service. |
