Belgian and Dutch gas operators Fluxys and Gasunie have entered a joint development agreement to construct a bidirectional cross-border hydrogen pipeline, the companies announced on Friday, April 10. 

According to the announcement, the project aims to integrate the national hydrogen networks of both countries by approximately 2030.

The connection is designed to establish an open-access transmission network in Northwestern Europe, a move intended to strengthen regional energy independence and accelerate industrial decarbonization. 

Gasunie subsidiary Hynetwork signed the agreement, emphasizing that the project will prioritize the repurposing of existing natural gas infrastructure for hydrogen transport where technically feasible.

“This connection will help realize the ambition to create an integrated, open, and accessible hydrogen transmission network,” Gasunie said in a statement.

The proposed connection point is centered on Zandvliet, a strategic Belgian town on the border, given its proximity to the major industrial hubs of Antwerp, Ghent, and Rotterdam. 

By linking these ports, the operators aim to create a seamless corridor for low-carbon energy.

Fluxys began the first phase of Belgium's national hydrogen network in March 2025, connecting the port areas of Antwerp and Ghent at a reported price tag of €330 million ($387 million). 

Meanwhile, Gasunie reached a significant milestone in January after filling a 32-kilometer stretch of the Dutch network—extending from Rotterdam’s Maasvlakte to industrial consumers—with green hydrogen.

Helmie Botter, Gasunie’s director of hydrogen transport, noted that cross-border trade is essential for a functioning European hydrogen market. 

"We’re making cross-border transport as easy as possible, empowering industry across Europe to go sustainable," Botter said.

The partnership represents a broader push for continental connectivity. Ben De Waele, director of hydrogen at Fluxys, confirmed the company is also developing infrastructure to link with other neighboring countries. 

These efforts are expected to form the backbone of a wider Northwestern European hydrogen grid, shifting the region away from fossil fuel reliance and toward a diversified, sustainable energy economy.
