Zelzate - Kallo

    Why this project?

    Fluxys is a key pioneer in the energy transition in Belgium.

    That’s why we’re preparing to build a hydrogen pipeline and a CO2 pipeline between Zelzate and Kallo. This new infrastructure will not only enable suppliers to bring hydrogen to market as a carbon-neutral energy carrier, but will also enable the CO2 harvested by companies to be transported between two major industrial clusters: the ports of Antwerp and Ghent.

    Connecting these two ports creates a strategic link that offers a future-oriented solution for the security of supply and decarbonisation of Belgium and neighbouring countries. Building these pipelines is also an important step in implementing Belgium's federal hydrogen strategy and the Flemish hydrogen vision, both of which aim to make our country a European hydrogen hub.

    Work to lay the pipelines and build the above-ground facilities is scheduled to start in 2025 (after the relevant permits are obtained).

    Facts and figures

    • The pipelines will be built on the territory of the towns of Zelzate, Wachtebeke, Moerbeke, Stekene, Sint-Gillis-Waas and Beveren.
    • Length of the pipelines: approximately 36 km
    • Diameter of the pipelines: 600 mm and 1000 mm


    Landowners and operators have their own point of contact at Fluxys, from the preliminary study of a project to the restoration of a site following the construction of a pipeline. This allows them to consult with someone familiar with their concerns and the features of their land from the outset.
