Public Consultation on H2 quality

Identification:

1. Please provide your name, your position, and the organisation you represent.

General considerations:

2. What do you consider to be the main purpose of hydrogen quality monitoring?

3. Several studies have been carried out and position papers have been issued on this topic. In your view, what is the main decision that needs to be made at this stage?

Infrastructure:

4. Do you agree that one of the most important principles is to build a single, interconnected hydrogen network without distinctions between hydrogen grades or types?

5. Do you agree that storage facilities represent the most critical link in the hydrogen value chain?

6. How do you assess the role of hydrogen transmission network operators (HTNOs)?

7. Do you agree that specifying hydrogen quality at entry points is a necessary and sufficient condition for HTNOs, provided that hydrogen is delivered at exit points in accordance with the entry specifications?

8. How do you assess the role of hydrogen distribution network operators (HDNOs)?

9. Do you identify any specific considerations or challenges related to terminals?

Purity levels and contaminants thresholds:

10. What do you consider more important: reaching a consensus on a unified hydrogen purity level in Europe, or primarily reaching a consensus on contaminants thresholds?

11. With regard to contaminants, do you believe that a consensus has already been reached on threshold values? What are the remaining areas of concern?

12. Do you think that standardisation bodies such as CEN/CENELEC should receive a clear mandate from the European Commission to issue specifications recognised by all Member States?

Production:

14. With regard to natural hydrogen (white hydrogen), do you foresee potential challenges in the event of an expansion of this type of production?

Consumption:

15. Different levels of purity are required depending on end uses. Do you believe that, if a globally high level of purity were specified across all interconnected European networks (e.g. >99.97%), local purification units (e.g. for fuel cells) could be avoided?

16. What do you consider to be the main priorities regarding data provided by HTNOs through a transparency platform?

Research and development:

17. Do you foresee significant innovation opportunities that could reduce hydrogen purification costs?

Regulation and cost allocation:

19. In a regulated framework, what would you consider to be the optimal approach to cost allocation for hydrogen purification processes?

20. Do you think that incentive mechanisms could be useful in relation to hydrogen quality?
