From islands to impact - Denmark helps wire Europe’s offshore future
Cross-border wind goes mainstream
The Hamburg Declaration marks a step in how offshore wind is planned and delivered. Instead of isolated national projects, the focus is now on cross-border cooperation, shared grids and coordinated investments across the North Seas.
As a first concrete move, transmission system operators and developers are already planning up to 20 GW of cooperation projects for the 2030s, paving the way for much larger volumes later on. The declaration also commits countries to closer offshore grid planning, faster permitting and a new Offshore Financing Framework to improve access to capital and fair cost sharing.
For investors, this matters. Cross-border projects reduce system costs, improve security of supply and create scale. For Denmark, it aligns directly with long-standing strengths in offshore wind, energy system integration and pragmatic public-private cooperation.
Bornholm Energy Island: turning ambition into infrastructure
If the Hamburg Declaration sets the direction, Bornholm Energy Island shows how to deliver.
Concluded at the North Sea Summit, the bilateral agreement between Denmark and Germany makes Bornholm Energy Island one of Europe’s most tangible examples of cross-border offshore cooperation. With 3 GW of offshore wind capacity connected to both countries, the project will supply electricity to around three million households and strengthen energy security on both sides of the border.
Bornholm Energy Island is also the world’s first multi-terminal HVDC hybrid interconnector and one of eight EU-prioritised Energy Highways. Backed by 645 million euros in EU funding, and jointly delivered by Energinet and 50Hertz, it sets a new standard for how countries can share costs, benefits and technical responsibility for offshore infrastructure.
For companies across the value chain, from grid technology and power electronics to offshore construction, digital solutions and energy services, it creates a real-world platform for innovation and scale.
Why Denmark is a natural partner
Denmark’s role in both the Hamburg Declaration and the Bornholm Energy Island is no coincidence. Over decades, Denmark has built deep capabilities in offshore wind deployment, grid integration, permitting and stakeholder coordination.
Just as importantly, Denmark offers a stable regulatory environment, strong institutions and a proven ability to align national ambitions with European frameworks. This makes Denmark an attractive base for international companies looking to take part in Europe’s next phase of offshore expansion, whether in wind, grids or offshore hydrogen.
As offshore renewable hydrogen also features prominently in the Hamburg Declaration, Denmark’s experience with Power-to-X and sector coupling adds another layer of opportunity for companies targeting hard-to-abate industries and new energy markets.
Europe is connecting. Denmark is enabling.
From Hamburg to Bornholm, the direction is set. Europe’s offshore energy future will be cross-border, coordinated and built at scale. Denmark is helping to connect the dots, quite literally, between countries, grids and markets.
For international companies looking to grow with Europe’s offshore energy system, Denmark offers a platform to build, test and scale solutions that will power a more secure and competitive Europe.
