Quality requirements

This LAP is concerned with the applicable Requirements for acceptable concentration of impurities in Hydrogen used for fuel across the partner countries


Quality Requirements describe requirements for acceptable concentration of impurities.

Pan-European Assessment:

Overall, purity requirements are defined by the ISO 14687–2 and SAE J2719_201511 international standards. Directive 2014/94/EU will be transposed and implemented in all Member States. As this Directive states, in Annex II, that the ISO 14687 standard shall be followed, the LAP is not assessed to be associated with any significant legal barrier

Nevertheless, due to the very high purity requirements for hydrogen, standard ISO 14687–2:2012 is costly to implement, measure and enforce. The companies engaged in proposing new H2 production technologies and / or HRS technologies have to invest in high performance “quality assurance” for the H2 produced and / or delivered. This can be viewed as an economic barrier; however, it is in the interest of all those involved in building the market for hydrogen and FCEVs to develop standards accepted by everyone and develop and improve technologies.

Importantly, purity requirements should be verifiable, which is not the case in many EU–MS. The reason for this is that there are just a few independent laboratories (in the world) who can verify the purity required by ISO 14687–2:2012. In other words, the purity of hydrogen for FCEV cannot be guaranteed because the required measurements to show compliance with the standard are expensive/not available. This can be viewed as an operational barrier; however, its severity is negligible at the moment.
