The Dutch national hydrogen network reached a critical milestone this week as Hynetwork, a subsidiary of Gasunie, completed the first direct connection between a production facility and the country’s emerging hydrogen infrastructure.

The connection was finalized at the Rotterdam Maasvlakte with a ceremonial "golden weld," linking the 200-megawatt Holland Hydrogen 1 plant to the newly developed pipeline. 

The work, executed by contractor Hanab, marks the first time a green hydrogen producer has been integrated into the national grid.

Infrastructure experts say the connection is a foundational step in the broader effort to decarbonize heavy industry across the Netherlands and northwestern Europe. 

By linking local production directly to a high-pressure network, the project creates a blueprint for transporting carbon-free energy to industrial clusters that have traditionally relied on fossil fuels.

The newly commissioned section consists of 32 kilometers of pipeline, much of it running parallel to the A15 motorway. Construction required precision engineering, as the hydrogen line occupies a crowded energy corridor alongside other critical utilities.

A significant portion of the route was developed in tandem with Porthos, a major carbon capture and storage project. For nearly 20 kilometers, the hydrogen and CO2 pipelines run parallel, separated by only 40 centimeters.

"Intensive collaboration between Hynetwork, Porthos, and our construction partners enabled us to coordinate schedules and ensure safety in these tight spaces," said Jan Willem Rongen, project manager for the Rotterdam Hydrogen Network. 

"This collaboration was essential to our success."

The completion follows rigorous testing earlier this year, during which the first 32-kilometer stretch was pressurized with green hydrogen.

Hynetwork officials stated that the Rotterdam connection serves as the starting point for a vast expansion. 

Plans are already underway to extend the infrastructure into a national and eventually international network, linking Dutch industrial hubs with those in neighboring European countries to foster a regional hydrogen economy.
