Hydrogen quality control

Based on the requirements of EN 17124:2022 Hydrogen fuel. Product specification and quality assurance. Proton exchange membrane (PEM) fuel cell applications for road vehicles, a quality control plan has to be developed and implemented for each hydrogen refueling station.

In 2019, the EU funded a project, Hydrogen Delivery Risk Assessment and Impurity Tolerance Evaluation, which published a report Report on European analytical capabilities for hydrogen purity according to ISO 14687 and quality assurance. It reported on three laboratories that have developed technologies to test hydrogen’s gas contaminants according to ISO 14687 and EN 17124:2018. They are:
