Vattenfall and Amsterdam Startup Explore Offshore Data Centres Powered by Wind Farms
Swedish energy giant Vattenfall and Amsterdam-based startup Project Enki have launched a joint study into building offshore data centres that would run entirely on electricity generated by North Sea wind farms, the companies announced in June.
The concept is elegantly simple: place data centres at sea, connect them directly to offshore wind turbines, and use the power that would otherwise go to waste due to grid congestion or low electricity prices. Rather than building expensive onshore grid connections for every megawatt of wind capacity, some of that power could be consumed locally by servers humming away on a platform in the North Sea.
Solving Two Problems at Once
The proposal addresses two of the Netherlands’ most pressing infrastructure challenges simultaneously. On one hand, the country’s electricity grid is severely congested, particularly in industrial regions, making it increasingly difficult to connect new renewable generation and new data centre capacity. On the other, the explosion of AI computing is driving unprecedented demand for data centre power — demand that onshore grids are struggling to meet.
Offshore data centres could bypass both constraints. They would use electricity at the source, require no new onshore grid connections, and could even employ seawater for cooling — a significant sustainability advantage over land-based facilities that typically rely on freshwater, increasingly a scarce resource during dry Dutch summers.
Early Days, but Serious Players
Vattenfall stressed that the project is still in its exploratory phase and that no specific locations have been identified. A company spokesperson noted that the facilities would not necessarily need to be built in Dutch waters; other North Sea locations are also under consideration.
Project Enki, the Amsterdam startup partnering with Vattenfall, specialises in sustainable digital infrastructure. The collaboration signals growing interest from both the energy and technology sectors in finding creative solutions to the compute-power bottleneck — especially as AI adoption accelerates across Europe.
North Sea as Europe’s Digital Backbone
The initiative aligns with broader North Sea energy cooperation among northern European nations, which have committed to dramatically expanding offshore wind capacity as part of a push for energy independence. If the Vattenfall-Enki concept proves viable, the North Sea could become not just Europe’s wind powerhouse but also its most sustainable data centre hub — turning the challenge of excess offshore generation into an opportunity for low-carbon computing at scale.
