ENNOH’s Public Consultation on future hydrogen Network Codes

Download here the Groundwork Paper.

Overview

The European Network of Network Operators for Hydrogen (ENNOH) is inviting stakeholders to provide feedback on the Preparatory Groundwork Paper in the Areas of Future Hydrogen Network Codes ("Groundwork Paper").

The Groundwork Paper sets out initial ideas and considerations on how future hydrogen market design could evolve. These ideas reflect ENNOH’s and its members’ early views on topics expected to shape future Hydrogen Network Codes, in line with Article 72 of Regulation (EU) 2024/1789 ("Gas & H2 Regulation").

Purpose of the Consultation

The consultation seeks to gather views from market participants, infrastructure operators, industry representatives, policymakers, and other interested stakeholders. Feedback will help ENNOH to better understand the sector’s priorities and challenges in developing an efficient, interoperable, and transparent hydrogen market.

Scope of the Groundwork Paper

The proposed considerations are organised according to the areas of potential future network codes specified in the Gas & H2 Regulation:

1. Access to hydrogen infrastructure — including principles for capacity allocation, balancing, tariffs and transparency.
2. Financing and de-risking mechanisms — such as inter-temporal cost allocation.
3. Interoperability and technical rules — covering hydrogen quality, blending, measurement, and cross-border system compatibility.
4. General considerations — on the overall role of hydrogen infrastructure and the coherence between future network codes.

Each section contains statements and brief explanations reflecting ENNOH’s current thinking.

How to Participate

Participants may:

• Comment on any or all proposed statements OR
• Provide general views on one or several of the above areas OR
• Submit broader perspectives on the future design of hydrogen markets.
