NZS ISO 14687:2024
Hydrogen fuel quality – Product specification
Standard sets out maximum permissible concentrations for many key impurities depending on the application and specifies the minimum
quality characteristics of hydrogen fuel as distributed for use in vehicular and stationary applications. It also provides more detailed requirements on fuel purity for specific applications.
An impurity’s impact varies according to its physio-chemical nature (inert impurities such as nitrogen are usually less harmful than reactive species such as hydrogen sulphide) and the equipment being used (for example, a boiler that combusts hydrogen will generally tolerate a higher concentration of impurities than would a vehicle using polymer electrolyte membrane fuel cell [PEMFC] technology).
ISO 14687 is already being used in many global jurisdictions. In Europe, for example, Directive 2014/94/EU of the European Parliament and of the Council of 22 October 2014, on the deployment of alternative fuels infrastructure, states that the hydrogen purity dispensed by hydrogen refuelling points shall comply with the technical specifications included in ISO 14687. In California, the state is using the ISO values as the SAE’s J2719 Hydrogen fuel quality for fuel cell vehicles is being revised.
This standard was prepared by the P3652 Hydrogen Standards Committee and is identical to and has been reproduced from ISO 14687:2019, hydrogen fuel quality – Product specification.
