The NGV 4 committee expanded its scope to address dispensing hydrogen for hydrogen gas powered vehicles. The activity includes the following standards projects:

                        This standard contains safety requirements for the material, design, manufacture and testing of gaseous hydrogen dispensers constructed entirely of new unused parts and materials. This standards does not apply to the nozzle; vehicle to station communication, compression and ancillary equipment, compressed hydrogen gas storage containers, vehicle fueling appliances for HGV, remote station or kiosk consoles and remote sequencing equipment and other remote equipment not supplied as part of the dispenser.

HGV 4.2            Hose and Hose Assemblies for Hydrogen Vehicles and Dispensing Systems

                        This standard contains safety requirements for the material. Design, manufacture and testing of gaseous hydrogen hose and hose assemblies which are used for (1) connecting the dispenser to the refueling nozzle, (2) use as part of a vehicle on-board fuel system, or 93) use as vent lines which carry gas to a safe location for either vehicle or dispensing systems.

HGV 4.3            Fueling Parameters for Hydrogen Dispensing System

                        This standard details safety performance requirements for gaseous hydrogen fueling station fueling station temperature compensation devices systems. It applies to newly manufactured systems designed primarily to adjust for full fill and to avoid over-pressurization of vehicle fuel storage containers under the operating temperature conditions specified in the standard. This standard does not apply to onboard vehicle temperature compensation systems or components.

   §  Steel tanks not covered

   §  Covers outdoor refueling, not indoor refueling

HGV 4.4            Breakaway Devices for Hoses Used in Hydrogen Vehicle Fueling Stations

                        This standard contains safety requirements for the material, design, manufacture and testing of newly manufactured fueling hose breakaway devices. This is not applicable to “Vehicle Refueling Appliances,” Dispenser Breakaway Devices or Vehicle Breakaway Components.

HGV 4.5            Priority and Sequencing Equipment for Gaseous Hydrogen Dispensing Systems

                        This standard applies to priority and sequencing equipment which are part of a gaseous hydrogen vehicle fueling system. This standard contains safety requirements for the design, manufacture and testing of the priority and sequencing systems for gaseous hydrogen dispensers which are designed primarily to provide compressed hydrogen for vehicle fueling stations. This standard does not apply to the pressure swing adsorber sequencing panel or the gas dryer sequencing panel.

HGV 4.6            Manually Operated Valves Used in Gaseous Hydrogen Vehicle Fueling Stations

                        This standard contains safety requirements for the design, manufacture and testing of automatic, pressure operated valves used in gaseous hydrogen vehicle fueling stations. This standard does not apply electrically actuated valves, hydraulically actuated valves, pressure regulating valves, pressure relief valves or fueling nozzle valves.

HGV 4.8            Hydrogen Gas vehicle Fueling Stations Compressor

                         This standard contains safety requirements for the design, manufacture and testing of gaseous hydrogen compressor packages used in fueling station service. This standard applies to newly manufactured equipment designed primarily to provide compressed hydrogen for vehicle fueling stations. This standard does not apply to vehicle fueling appliances for HGV or compressor packages used for nonvehicular fuel appliances
