As AI-driven demand strains global power grids, startups are exploring unconventional solutions to feed energy-hungry data centers. One company believes the ocean — not orbit — is the answer.

Submerged Servers Beneath Wind Turbines

Offshore wind developer Aikido is preparing to deploy a 100-kilowatt demonstration data center off the coast of Norway later this year.

The unit will be housed inside submerged pods attached to a floating offshore wind turbine. If the pilot proves successful, Aikido intends to scale the concept with a commercial installation off the coast of the United Kingdom in 2028.

That larger project would pair a 15–18 megawatt turbine with a 10–12 megawatt data center, directly powered by the wind asset overhead.

Why Move Data Centers Offshore?

The offshore model aims to tackle several mounting challenges in the AI infrastructure race:

1. Direct access to power
Locating servers directly beneath a turbine reduces transmission constraints and grid bottlenecks.

2. More consistent wind generation
Offshore winds tend to be steadier than onshore equivalents, with batteries potentially smoothing short lulls.

3. Reduced local opposition
By placing infrastructure offshore, companies may avoid “not in my backyard” (NIMBY) concerns tied to noise and land use conflicts.

4. Easier cooling
Cold seawater offers a natural thermal sink. Cooling remains one of the largest operational challenges for AI data centers — particularly for more speculative orbital proposals that must operate in vacuum conditions.

Not the First Attempt

The concept of underwater data centers is not entirely new.

More than a decade ago, Microsoft began exploring submerged server facilities under its Project Natick initiative. In 2018, the company deployed a test unit off the coast of Scotland. During the 25-month trial, only six of more than 850 servers failed — a relatively low failure rate, potentially aided by filling the sealed data hall with inert nitrogen gas.

Microsoft later open-sourced related patents in 2021 but discontinued the project in 2024.

Engineering Challenges Remain

While offshore deployment may solve siting and cooling issues, it introduces new technical hurdles:

  • Corrosion risk: Seawater is highly corrosive, requiring hardened containers and reinforced power/data connections.
  • Structural stability: Though shielded from direct wave impact, submerged units would still experience motion and must be securely anchored.
  • Maintenance logistics: Servicing underwater facilities is inherently more complex than land-based alternatives.

Ocean vs. Orbit

The renewed interest in unconventional siting reflects the severity of the AI power crunch. Some industry figures have floated space-based data centers powered by continuous solar exposure.

Aikido’s approach suggests a more grounded — or submerged — alternative: colocating compute directly with renewable energy infrastructure in environments that naturally address cooling constraints.

If the Norwegian pilot proves viable, offshore wind-powered data centers could become a niche but scalable option in the race to power next-generation AI systems.
