The HY4Link project, a collaborative effort led by Creos Luxembourg, Fluxys hydrogen, and GRTgaz, is a pioneering cross-border initiative aimed at establishing a hydrogen transport infrastructure linking Belgium, Luxembourg, the Grand Est region in France, and the Federal State of Saarland in Germany. This initiative has been recognized in the European Hydrogen Network’s Ten-Year Development Plan, marking a crucial step towards its identification as a Project of Common Interest. The partnership between the three companies will focus on evaluating consumption and transit needs in the Greater Region before proceeding with feasibility studies. One of the main objectives of the HY4Link project is to connect industries in the involved countries to hydrogen import hubs, such as Antwerp, Zeebrugge, Rotterdam, and Dunkirk, to promote local production of renewable hydrogen and establish the necessary infrastructure for its transportation. By creating links between France and Luxembourg, as well as Belgium and Luxembourg, the project aims to develop a comprehensive hydrogen backbone that facilitates the regional production and transport of hydrogen. The project's second phase involves constructing a hydrogen pipeline across Luxembourg to France and Germany, integrating with existing corridors and storage projects. Pascal De Buck, Director and CEO of Fluxys, highlighted the importance of cross-border networks for securing hydrogen supplies, while Sandrine Meunier, Managing Director of GRTgaz, emphasized the contribution of HY4Link towards building a regional hydrogen economy. Laurence Zenner, CEO of Creos Luxembourg, noted that the project would significantly support decarbonization initiatives in Luxembourg and the Greater Region by connecting industrial demand centers with green hydrogen producers. HY4Link is envisioned as a crucial player in Europe’s energy transition, aiming to reduce carbon emissions in industry and transport while fostering sustainable job creation and ensuring long-term regional prosperity.
