CEN/TC 268/WG 5 - Specific hydrogen technologies applications

This document defines the minimum requirements to ensure the interoperability of hydrogen refuelling points, including refuelling protocols that dispense gaseous hydrogen to road vehicles (e.g. Fuel Cell Electric Vehicles) that comply with legislation applicable to such vehicles.
The safety and performance requirements for the entire hydrogen fuelling station, addressed in accordance with existing relevant European and national legislation, are not included in this document.
This document applies to hydrogen refuelling points dispensing gaseous hydrogen to vehicles compliant with UN R134 (Regulation No. 134), UN R134 or Regulation (EC) No 79/2009.
NOTE 1   Guidance on considerations for hydrogen fuelling stations is provided in ISO 19880 1:2020.
NOTE 2   Units used in this document follow SI (International System of Units).

This document specifies the quality characteristics of hydrogen fuel dispensed at hydrogen refuelling stations for use in proton exchange membrane (PEM) fuel cell vehicle systems, and the corresponding quality assurance considerations for ensuring uniformity of the hydrogen fuel.

This document defines the design, safety and operation characteristics of gaseous hydrogen land vehicle (GHLV) refuelling connectors.
GHLV refuelling connectors consist of the following components, as applicable:
—     receptacle and protective cap (mounted on vehicle);
—     nozzle;
—     communication hardware.
This document is applicable to refuelling connectors which have nominal working pressures or hydrogen service levels up to 70 MPa.
This document is not applicable to refuelling connectors dispensing blends of hydrogen with natural gas.

This document specifies the quality characteristics of hydrogen fuel and the corresponding quality assurance in order to ensure uniformity of the hydrogen product as dispensed for utilization in proton exchange membrane (PEM) fuel cell road vehicle systems.

This document defines the minimum requirements to ensure the interoperability of public hydrogen refuelling points including refuelling protocols that dispense gaseous hydrogen to road vehicles (e.g. Fuel Cell Electric Vehicles) comply with applicable regulations.
The safety and performance requirements for the entire hydrogen refuelling station (HRS), addressed in accordance with existing relevant European and national legislation, are not included in this document.
NOTE   Guidance on considerations for hydrogen refuelling stations (HRS) is provided in ISO/TS 19880-1.

ISO 17268:2012 defines the design, safety and operation characteristics of gaseous hydrogen land vehicle (GHLV) refuelling connectors consisting of, as applicable, a receptacle and a protective cap (mounted on vehicle), and a nozzle.
It applies to refuelling connectors which have working pressures of 11 MPa, 25 MPa, 35 MPa and 70 MPa, referred to as
H11 - 11 MPa at 15 °C,
H25 - 25 MPa at 15 °C,
H35 - 35 MPa at 15 °C,
H35HF - 35 MPa at 15 °C (high flow for commercial vehicle applications), and
H70 - 70 MPa at 15 °C.
Nozzles and receptacles that meet the requirements of ISO 17268:2012 will only allow GHLVs to be filled by fuelling stations dispensing hydrogen with nominal working pressures equal to or lower than the vehicle fuel system working pressure. They will not allow GHLV to be filled by fuelling stations dispensing blends of hydrogen with natural gas.
Refuelling connectors dispensing blends of hydrogen with natural gas are excluded from the scope of ISO 17268:2012.
