Infrastructure development plans

Indicative investment plans: natural gas, hydrogen and CO₂ infrastructure

Fluxys publishes indicative investment and network development plans that provide transparency on how its planned investments align with market needs, security of supply and the energy transition. The plans make a clear distinction between the separate infrastructures for different carriers: the natural gas infrastructure plan covers the 2026–2035 period, while the hydrogen infrastructure plan by Fluxys hydrogen covers 2025–2034. CO₂ transmission infrastructure will be addressed in separate 2026–2035 network development plans by Fluxys c-grid and Fluxys c-grid Antwerp.

Indicative investment plan natural gas infrastructure 2026-2035

The Indicative investment plan natural gas infrastructure of Fluxys Belgium covers the investments in natural gas infrastructure the company envisages in the 2026-2035 period. Included are the investments for both Fluxys Belgium and Fluxys LNG in Belgium’s natural gas transport and storage infrastructure as well as the Zeebrugge LNG terminal. The plan focuses exclusively on natural gas infrastructure and is designed to keep the network robust, reliable and fit for future needs while supporting the energy transition.

• Maintain, adapt and modernise Fluxys Belgium’s natural gas transmission network, storage infrastructure and the Zeebrugge LNG terminal so they remain safe, reliable and able to respond to changing market flows.
• Invest in methane infrastructure that is fit for the future, including biomethane injection, backbone upgrades and the Zeebrugge-Evergem multipurpose pipeline, which can later be used for hydrogen or CO₂ as market needs evolve.
• Reduce the greenhouse gas emissions of Fluxys Belgium’s own activities, with planned investments in areas such as open rack vaporisers, solar panels, heat pumps and methane emission reduction programmes.
• Strengthen digitalisation, cybersecurity and AI capabilities to manage gas flows, maintain resilient operational systems and prepare the digital environment for future multi-molecule infrastructure.

The plan was drawn up in accordance with Article 15/13, §2, 3° of the Gas Act of 12 April 1965 and reflects the role of the natural gas network in system adequacy, security of supply and future flexibility.

Please note: unlike previous editions, this natural gas infrastructure plan no longer includes indicative investments for hydrogen and CO₂ infrastructure. The hydrogen network development plan by Fluxys hydrogen is published separately for 2025–2034. The CO₂ network development plans by Fluxys c-grid and Fluxys c-grid Antwerp are to be published separately for 2026–2035, in line with the regulatory framework.

Indicative investment plan for hydrogen 2025-2034

As Belgium’s designated Hydrogen Network Operator (HNO), Fluxys hydrogen 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.
