Idomlund hydrogen projects in north-west Jutland have been given a political boost from Brussels after the European Commission granted two Power-to-X (PtX) projects in the Holstebro area the status of Projects of Common Interest (PCI). The move strengthens their access to EU funding and faster permitting, but it also reopens a Danish debate: the government’s first hydrogen pipeline to Germany is planned to reach Esbjerg, not Idomlund, leaving local actors warning that the EU “stamp of approval” risks being worth little without the missing connection.
Why the EU’s PCI label matters for Idomlund PtX
The PCI designation is part of the EU’s updated list of 235 cross-border energy projects aimed at accelerating infrastructure for electricity, hydrogen and CO₂ transport. Projects on the list can benefit from streamlined authorisation procedures and may apply for support under EU programmes such as the Connecting Europe Facility.
For the Idomlund area, the label functions as a signal to investors that the projects fit into a wider European strategy: scaling renewable hydrogen production and moving it to industrial demand centres, especially in Germany. In practice, however, PCI status does not build pipelines on its own.
Idomlund’s pitch: offshore wind, PtX and a west Jutland energy hub
Idomlund, in Holstebro Municipality, has been positioned by Danish stakeholders as a future green energy node. The location is linked to a growing network of renewable generation in western Denmark, including planned offshore wind capacity in the North Sea.
Two PtX projects in the area—developed by RWE and Plug Power—are designed to convert electricity from wind and solar into hydrogen (and potentially derivatives such as e-fuels). The argument from local actors is straightforward: if Denmark wants to export green molecules to German industry at scale, production sites near abundant renewables should be connected to the backbone.
The ‘Syvtallet’ pipeline: Denmark starts with Esbjerg
The Danish government and a broad parliamentary majority agreed in February 2025 to support the first stage of a hydrogen pipeline from Germany to Esbjerg, often called the “Syvtallet” because of its planned route. The agreement includes a state loan of DKK 7.4 billion (about €992 million) and up to DKK 8.3 billion (about €1.07 billion) in operating support, with the aim of enabling exports around 2030.
This first-stage focus is defended by the government as a pragmatic way to “get the market started” and secure an initial route to German demand. But it also leaves unresolved the question of the northern extension—an issue that matters for Idomlund.
The Idomlund paradox: EU backing without a Danish connection
Local representatives and some politicians argue that the EU’s decision creates a paradox: Brussels labels the projects strategic, while Denmark’s current pipeline plan stops further south.
In the short term, the practical constraint is clear. PtX facilities require reliable infrastructure to move hydrogen (or converted products) to customers. Without a pipeline extension toward Idomlund—or alternative logistics that are economically viable at scale—the projects risk remaining on paper or progressing more slowly than anticipated.
What Copenhagen says: ‘the beginning, not the end station’
Denmark’s Ministry for Climate, Energy and Utilities (Klima-, Energi- og Forsyningsministeriet) has argued that the Esbjerg route is a first step rather than a final design. The government maintains that the longer-term ambition of a fuller Jutland hydrogen backbone has not been abandoned, even if sequencing has changed.
Industry voices have also pointed to a market reality: the hydrogen and PtX sector has matured more slowly than many expected, making it politically easier to justify a staged build-out.
What happens next for Idomlund hydrogen projects
The key question is timing. If Denmark moves quickly from the Esbjerg stage to later phases, the Idomlund area could still become a meaningful production hub for the German market. If the extension remains uncertain, PCI status may mainly offer administrative advantages—not the infrastructure certainty that multi-billion-euro industrial investments typically require.
For the EU, the case illustrates a broader challenge: turning a Union-wide hydrogen strategy into buildable projects depends not only on Brussels-level “priority lists”, but also on national infrastructure choices and the pace at which demand, regulation and financing converge across member states.
