Quality measurement requirements

Quality measurement requirements

This LAP is concerned with the methods, analyses and devices used for the assessment and assurance that the hydrogen, delivered at the distribution centers and at refueling stations, meets the requirements for hydrogen purity.

General Assessment:

The transposition of the Directive 2014/94/EU, has led to a regulation on H2 as an energy carrier for road transport, but the quality measurement requirements have not been fixed in this legislative act.

A legally mandated quality control procedure exists in most countries in which HRS have been installed and advanced discussions are in place in the others. Nevertheless, approaches differ considerably with respect to both the fuel quality requirements, measurement and process.
Most countries adhere (from a regulatory perspective) to the standards laid down within ISO 14687-2 and ISO 19880–1, however, from an administrative and operational perspective some countries have taken different approaches. The general message across different countries with experience in deployment of hydrogen as fuel is that the ISO norm forms the basis for the quality control, but that checking on all the possible contaminants is very difficult/expensive. In practice measurement is done on key contaminants which are checked continuously, however, due to the associated costs, not all contaminants named in the norm are checked.
