- Denmark will raise long-term support for its hydrogen pipeline to Germany from DKK10.9bn to DKK16.5bn and temporarily guarantee up to DKK2.1bn of stranded costs.
- Developers must indicate demand for 0.5 GW of capacity this year, but only 0.1 GW must become financially guaranteed by the end of 2027.
- The agreement offers Britain a preview of the volume and sequencing risks likely to confront its own first hydrogen networks.
Denmark has agreed to absorb more of the early commercial risk surrounding a planned hydrogen pipeline to Germany, effectively ensuring that the strategic infrastructure can proceed with only a small volume of firmly committed demand.
A broad parliamentary agreement will increase the operating-support reserve for the Syvtallet pipeline by DKK5.6bn, taking total support to DKK16.5bn between 2030 and 2059, the Danish climate and energy ministry announced.
The state will also guarantee up to DKK2.1bn of Energinet’s potentially stranded development costs until the beginning of 2028. The government said the pipeline would be built if at least one qualifying project ultimately used it.
Climate and Energy Minister Samira Nawa acknowledged the risk, saying: “We enter the project with our eyes open: the hydrogen market is still immature.” Nevertheless, she said Syvtallet “must be built”.
The pipeline will run from the Esbjerg area through southern Jutland to the German border, connecting Danish hydrogen producers to customers on Germany’s developing core network. Energinet is working towards commissioning by the end of 2030, although it describes the timetable as tight.
Demand gap
Developers are still expected to indicate collective demand for 0.5 GW of pipeline capacity by 1 December 2026. Those reservations will no longer be binding, however.
The capacity sale will continue until November 2027, with developers only needing to provide financial guarantees covering 0.1 GW by the end of that year. They may also exit their capacity contracts before then if the economics of their projects cease to work.
The changes respond directly to warnings that producers were being asked to accept major pipeline liabilities before Energinet had taken a final investment decision.
Energinet said the revisions would give companies more time to mature projects and complete support agreements. Michael Linnemann Pedersen, its head of megaprojects, described the pipeline as a “large and complex project with an ambitious timetable” in the network operator’s announcement.
There is a prospective supply base. Five Danish projects have been selected for almost DKK12bn of German and EU support, according to the ministry.
Three of these secured backing from Germany’s €1.3bn Auctions-as-a-Service window. The Frigg, Heimdal and HØST projects represent 590 MW of electrolyser capacity and approximately 78,000 tonnes of annual hydrogen production from 2031. Their subsidy bids ranged from €0.98 to €1.70 per kilogram over ten years, according to the German economy ministry.
The Danish agreement is best understood as a state-backed option on a future hydrogen market. Reducing the guaranteed booking threshold by 80% makes construction more likely, but it also transfers underutilisation risk from early users to taxpayers.
That lesson is relevant to the UK, where the government intends the first regional hydrogen transport and storage network to operate from 2031 and has committed more than £500m to infrastructure development. Its policy framework explicitly recognises uncertainty over how quickly demand will emerge.
Denmark shows that production subsidies, pipeline finance and industrial offtake cannot be developed as separate markets. Unless their timetables and risk allocation align, government eventually becomes the counterparty holding the system together. The question is no longer whether public support will be needed, but which risks the state accepts and what evidence of future demand it requires in return.
