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.

Glossary:

Fualy quality measurements requirements are requirements for methods and technologies for testing and analysing the quality of hydrogen as a fuel.

Pan-European 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.
Is it a barrier?

Assessment
The lack of specified requirements as to when and to what extent quality will be tested seems to give the actors a certain freedom in this area. This can have both positive and negative aspects.

Some may incur unnecessarily high costs, from testing very often, while others may limit costs by testing more rarely.

Questions:

Question 1 Is there a quality control for hydrogen as a fuel? If yes: a) Which is the competent authority? b) Which entity is responsible for the hydrogen quality? c) What are the quality criteria? d) What are the frequency of the quality measurements?
yes
Question 1 Is there a quality control for hydrogen as a fuel? If yes: a - Which is the competent authority?
a - The Norwegian Environment Agency is responsible for ensuring its national and international acceptance, and national measurement standards.
Question 1 Is there a quality control for hydrogen as a fuel? If yes: b - Which entity is responsible for the hydrogen quality?
b - Both the producer/supplier and those operating the filling stations are responsible, that is obliged to follow the standards. Other than this, a recent regulation changing chapter V of the national Product Regulation lays down a method for calculating greenhouse gas intensity, and provides a simplified method for reporting from SMEs based on average GHG emissions, also for hydrogen. These are mandatory.
Question 1 Is there a quality control for hydrogen as a fuel? If yes: c - What are the quality criteria?
c - As defined by SAE J2719_201511 Hydrogen Fuel Quality for Fuel Cell Vehicles.
Question 1 Is there a quality control for hydrogen as a fuel? If yes: d - What are the frequency of the quality measurements? Is there a quality control for hydrogen as a fuel? If yes:
d - There are no rules for how often or what to measure. The fuel providers work to fulfil the standard requirements and use on–line analysers and lab testing to the extent they find it necessary. SINTEF has been testing fuel from Norwegian hydrogen refuelling stations.
