World first: Bornholm will become the energy hub between Germany and Denmark!
Germany and Denmark are strengthening their offshore energy partnership for the energy transition with a new interconnector by 2025.

World first: Bornholm will become the energy hub between Germany and Denmark!
In a groundbreaking initiative, Germany and Denmark today strengthened their offshore energy partnership. A central element of this collaboration is the Bornholm Energy Island, which acts as the first hybrid interconnector between the two countries. This innovative connection will include an offshore wind farm with an impressive capacity of 3 GW, which will be built as part of the new electricity connection in the Baltic Sea. This is reported by the Federal Ministries for Economic Affairs and Climate Protection.
Why is this so important? The two countries are doing everything they can to increase security of supply and integrate renewable energy sources such as offshore wind power and hydrogen more effectively. The cooperation is intended to create synergies in energy production, consumption and cross-border electricity trading. At the same time, the goal is to reduce dependence on Russian gas.
Energy hubs for the future
The specific plan is to build an energy hub on the island of Bornholm. bornholmenergyisland.eu reports that this hub will provide electricity to consumers in both countries, tailored to market and demand. Thanks to innovative technology, electricity from wind turbines off the coast of Bornholm is centralized and converted into high-voltage direct current. This is then transported via a sophisticated 525 kV HVDC sea and land cable system to substations in Denmark and Germany.
The choice of location on Bornholm is not a coincidence. This project will connect the local community with Zealand and mainland Europe and is part of efforts to bring a European hydrogen network into operation by 2030. Green hydrogen production from Denmark will ensure a reliable energy supply for German companies.
A step in the right direction
The cooperation between both countries is supported by the EU, which is another sign of the importance of the project. In addition to supporting the expansion of infrastructure, the energy ministers of Germany and Denmark also advocated better networking of energy systems in Europe. This became particularly clear at the first bilateral meeting between the two energy ministers after Katherina Reiche (Germany) took office, who sees energy cooperation with Denmark as a key priority.
Lars Aagaard, Danish Energy Minister, highlighted the importance of bilateral cooperation in the areas of renewable energy and hydrogen projects. This is not only an example of successful regional cooperation, but also an important step towards a climate-neutral EU by 2050. According to Wind-energie.de, the EU has the firm goal of reducing emissions by 50 to 55 percent by 2030 and is also relying on extensive investments in renewable energies.
The Bornholm Energy Island project not only strengthens regional cooperation, but also promotes the practical implementation of the goals of the European “Green Deal”. The project illustrates how important it is to find innovative solutions to the challenges of the energy transition - while also keeping an eye on the availability of jobs.
