Low-carbon hydrogen is set to play an important role in the energy transition, particularly in reducing CO₂ emissions in industry and heavy transport. To support this development, Luxembourg is setting up a national hydrogen transport network.
This future network will enable hydrogen to be transported safely and efficiently between production sites and users. It will constitute a new energy infrastructure, complementing existing networks, and will support the development of a hydrogen economy in Luxembourg and the region.
As of 1 December 2025, Creos Luxembourg Hydrogen S.A., a wholly-owned subsidiary of Creos Luxembourg S.A., has been officially designated by the Luxembourg government as the national manager of the hydrogen transport network. In this capacity, Creos Hydrogen is responsible for:
Drawing on Creos' recognised expertise in managing critical energy infrastructure, Creos Hydrogen will establish a structured and transparent framework, enabling industrial and energy players to invest in low-carbon solutions with long-term visibility.
A network connected to Europe
The future Luxembourg network has been designed from the outset as an interconnected infrastructure, fully integrated with European developments. To this end, Creos Hydrogen is developing the HY4Link project in cooperation with Fluxys Hydrogen in Belgium and Natran in France.
This strategic energy corridor aims to connect Luxembourg to the European Hydrogen Backbone (EHB), the future European hydrogen transport network, and to facilitate cross-border exchanges. This integration will strengthen security of supply, support industrial competitiveness and position Luxembourg as a key player in the European hydrogen market.
Creos Hydrogen and NaTran will join forces to develop an interconnected hydrogen network linking Bouzonville (France) to Frisange in southern Luxembourg via Thionville, with a connection to the mosaHYc project. This cross-border interconnection between France and Luxembourg is the first step in establishing hydrogen infrastructure in southern Luxembourg, representing approximately 40 km of network.
In cooperation with Fluxys Hydrogen, Creos Hydrogen will build a pipeline connecting Luxembourg to the Belgium Hydrogen Backbone via the Bras (Belgium) border crossing point. This project will be complemented by the construction of a hydrogen pipeline across Luxembourg, comprising a network of approximately 80 km providing connections to France and Germany.
HY4Link plays a pivotal role for the decarbonization efforts in Luxembourg and the Greater Region by enabling various sectors e.g. industry and transport, to switch from fossils to clean hydrogen. As such, the project facilitates the region’s decarbonization efforts at large.
An important pillar of the energy transition is the creation of sustainable development and growth. HY4Link will contribute to these objectives by boosting sustainable job opportunities and investments that contribute to the long-term prosperity of the entire Greater Region.
Via its cross-border interconnections between Belgium, Germany, France, and Luxembourg HY4Link markedly advances further integration of the Greater Region. For instance, HY4Link’s pipeline system will directly connect market players such as green hydrogen producers with hydrogen consumers across the region.
