HomeOffshore Floating Data Centers Emerge as Earthbound Alternative
The energy demands of AI data centers have become so intense that discussions are emerging about deploying servers into space to harness continuous solar power – and it's not just Elon Musk proposing this.
One startup believes the ocean offers a more viable alternative. Offshore wind developer Aikido intends to submerge a 100-kilowatt demonstration data center off Norway's coast this year. The compact unit will be housed within the submerged sections of a floating offshore wind turbine.
If the trial succeeds, the company aims to construct a larger version for deployment off the UK coast by 2028. That upgraded model will feature a 15 to 18 megawatt turbine supplying power to a 10 to 12 megawatt data center.
Moving offshore addresses several key challenges. Direct access to power is an obvious advantage, with the energy source positioned directly above. Offshore winds are more consistent than on land, and a small battery system could manage any temporary calm periods.
Submerged data centers could also alleviate opposition from NIMBY groups – "not in my backyard" – who often resist nearby data centers due to noise and environmental concerns.
Additionally, floating in cold seawater simplifies server cooling. (This contrasts with orbital data centers, where cooling presents particular difficulties in the vacuum of space.)
However, while offshore data centers solve certain problems, they introduce new complications. The marine environment is notoriously harsh. Although submerged servers would avoid direct wave impact, they wouldn't remain perfectly stationary, requiring secure fastening. Seawater's corrosive nature also demands specially designed equipment – including the container, power, and data connections – with enhanced corrosion resistance.
Aikido isn't pioneering the concept of underwater data centers. Microsoft first explored the idea over ten years ago and conducted a moderately successful experiment off Scotland in 2018. During the 25-month trial, only six out of more than 850 servers failed. (The data hall was filled with inert nitrogen gas, which likely contributed to the low failure rate.)
Microsoft secured numerous patents over the years, making them openly available in 2021. However, by 2024, the company had discontinued the project.

Interesting idea, but floating data centers? The ocean is already struggling with pollution and temperature changes. Wouldn't this just add more heat and risk to marine ecosystems? Seems like we're solving one problem by creating another. 🌊🤔
