Infrastructure development plans

Indicative investment plans 2025–2034: Natural gas & hydrogen

Fluxys is committed to shaping Belgium’s energy infrastructure for a sustainable future. In line with the energy transition and evolving market needs, we have published two indicative investment plans for the period 2025–2034: one for natural gas and one for hydrogen. These plans provide transparency on anticipated infrastructure developments while remaining adaptable to future changes.

Indicative investment plan for natural gas

The Indicative 10-Year Investment Plan for Natural Gas outlines the investments required to:

• Maintain and upgrade Fluxys Belgium’s transmission and storage infrastructure, as well as the Zeebrugge LNG terminal.
• Support Belgium’s natural gas market evolution while meeting greenhouse gas (GHG) reduction targets for our installations.
• Ensure new major investments are compatible with the energy transition, either by reducing emissions or by enabling multipurpose infrastructure.

This plan is prepared in accordance with Article 15/13, §2-3° of the Gas Decree (April 12, 1965).

Please note: Compared to previous editions, hydrogen and CO₂ infrastructure investments are no longer included here. Separate documents address these areas in line with updated regulatory frameworks. The Indicative 10-Year Investment Plan for CO₂ is in production.

Indicative investment plan for hydrogen

As Belgium’s designated Hydrogen Network Operator (HNO), Fluxys has published its first Indicative 10-Year Investment Plan for hydrogen for 2025–2034. This plan:

• Identifies the most mature transport infrastructure needs to connect hydrogen supply and demand, both domestically and for import/transit.
• Serves as input for the hydrogen transmission tariff proposal (2026–2028) and for Fluxys’ re-certification as HNO under updated EU regulation (Directive 2024/1788, Regulation 2024/1789).
• Provides a non-binding, evolving framework based on market consultations, ensuring transparency while remaining flexible to future developments.

Prepared under Article 14 of the Federal Hydrogen Law (Belgian Official Gazette, 25 July 2023), this document is an interim network development plan ahead of the official proposal due by 1 July 2027.
