The requirement for TPRDs or PRDs on hydrogen storage vessels in mobile systems depends on jurisdictional regulations and performance testing outcomes.
In a mobile transportation hydrogen storage system, is it required to have a TPRD or PRD (Pressure Relief Device) on each vessel in the system?
Requirements for TPRD/PRD’s depend on the local regulations. Some jurisdictions require them, some do not. Others make them optional based on results of performance testing.
