Startup Aikido plans submerged data centers powered by offshore wind, offering a new solution to the growing AI power crunch.
The AI power problem is pushing data centers to extreme locations
The race to power AI data centers has become so intense that some technologists are discussing placing servers in space to access constant solar energy.
But one startup believes the ocean is a far more practical option.
Offshore wind developer Aikido plans to deploy a 100-kilowatt submerged data center off the coast of Norway later this year. The system will sit inside underwater pods attached to a floating offshore wind turbine, allowing servers to run directly off renewable power.
In short, instead of sending data centers into orbit, Aikido wants to sink them beneath the sea.
A prototype in Norway, a larger system planned for the U.K.
The upcoming Norwegian deployment is a demonstration unit designed to test how submerged computing infrastructure performs in real ocean conditions.
If successful, Aikido intends to scale the concept dramatically.
The company’s next planned system, targeted for 2028 off the U.K. coast, would combine a large wind turbine with an underwater data facility.
Key specifications include:
- 15–18 megawatt offshore wind turbine
- 10–12 megawatt submerged data center
- Direct integration between power generation and computing infrastructure
This architecture could place computing power right next to its energy source, eliminating one of the biggest constraints in AI infrastructure: electricity supply.
Why the ocean could solve several data center problems
Moving data centers offshore offers several practical advantages.
First, power availability improves dramatically. Offshore winds are generally stronger and more consistent than on land, making them ideal for continuous computing workloads.
A modest battery system could handle short gaps in wind generation.
Second, offshore installations could reduce community opposition.
Many cities resist new data centers due to concerns over noise, energy consumption, and local environmental impact—a phenomenon often called NIMBY (“not in my backyard”) resistance.
Placing facilities at sea removes that conflict entirely.
Finally, cooling becomes far easier.
Servers generate enormous heat, and cooling infrastructure already accounts for 30–40% of a typical data center’s energy use. Submerged systems could use the surrounding cold seawater as a natural heat sink.
Compared with space-based servers—where cooling in a vacuum requires complex engineering—the ocean looks relatively simple.
But the ocean introduces new engineering challenges
Despite the advantages, underwater computing isn’t trivial.
The ocean is an extremely harsh environment for hardware.
Even if submerged data centers sit below surface waves, they will still experience constant motion from ocean currents.
That means the infrastructure must be securely stabilized and reinforced.
Another issue is corrosion. Saltwater aggressively degrades metals and electronics, so:
- Containers must be fully sealed and hardened
- Power and fiber connections must resist saltwater exposure
- Maintenance logistics become more complicated
In short, the ocean may solve the energy and cooling problem—but it introduces serious durability challenges.
Microsoft tried underwater data centers first
Aikido isn’t the first company to explore this idea.
Microsoft launched an underwater data center experiment in 2018 off the coast of Scotland as part of its Project Natick research program.
The results were surprisingly strong.
During the 25-month test, only six of more than 850 servers failed—a lower failure rate than many land-based facilities.
The container was filled with inert nitrogen gas, which likely helped reduce hardware degradation.
Microsoft later open-sourced the patents in 2021, but by 2024 the company shelved the project, effectively ending the experiment.
The bigger question: where should AI infrastructure live?
The AI boom is forcing the tech industry to rethink where computing infrastructure belongs.
Options now being discussed include:
- Space-based solar-powered data centers
- Floating offshore facilities
- Submerged underwater computing pods
Each idea reflects the same underlying reality: AI is consuming electricity faster than traditional infrastructure can supply it.
So the next generation of data centers may not just be bigger.
They may be in entirely new places.
TL;DR:
Startup Aikido plans to deploy a submerged AI data center powered by offshore wind near Norway. The concept could solve power, cooling, and land-use challenges facing modern data centers, though ocean corrosion and stability pose engineering risks. Microsoft previously tested similar underwater systems.
