What do you get if you mix distressed offshore wind power websites, surging AI power calls for, and not-in-my-backyard sentiments in the direction of information facilities? One firm is combining all three issues into an answer: floating offshore information facilities.
One of many greatest considerations in AI is the large quantity of power it requires. In 2025 alone, AI information facilities consumed 448 TWh of electrical energy, roughly equal to Germany’s annual electrical energy consumption. Business analysts challenge this quantity might double in simply 5 years.
These ranges of consumption place extreme pressure on native grids and lift pertinent questions on AI sustainability, particularly now that the world is accelerating its transition to wash power.
Researchers and engineers are racing to develop sustainable options that scale back AI information facilities’ reliance on the grid. This normally means producing clear power on-site. Nevertheless, even these efforts are assembly resistance. The speed at which information facilities are popping up throughout the US and Europe is driving not-in-my-backyard sentiment in the direction of each the amenities themselves and the power infrastructure wanted to energy them. Communities are involved about land use, power consumption, and environmental impression.
Aikido Applied sciences, a San Francisco-based firm, might have discovered a method to clear up each issues directly by transferring all the operation out to sea.

The startup, greatest recognized for growing floating offshore wind platforms, has proposed an idea known as the AO60DC, which integrates a big offshore wind turbine, battery storage, and a modular information heart right into a single construction. Principally, a wind-turbine/data-center hybrid. As a substitute of constructing server farms on land and operating lengthy transmission strains from distant wind farms, Aikido’s design locations computing infrastructure immediately on the supply of renewable power, colocating energy era, computing, cooling, and power storage on a single floating platform.
“Over the previous yr, as we watched the rising challenges round powering and cooling new information facilities, we realized our platform already had ample energy and successfully free cooling inbuilt. It hit us like a ton of bricks,” mentioned the CEO of Aikido, Sam Kanner.

The platform resembles a floating offshore wind basis with three giant structural legs. Inside these legs are sealed data-center modules housing racks of servers. The wind turbine mounted atop generates electrical energy that powers the computing techniques under, whereas the encompassing seawater cools them.
General, the idea itself is elegantly easy. Nevertheless, the precise engineering behind all of it is something however.
The system consists of a big platform that helps the turbine within the heart, with three legs extending out from the bottom of the tower. The tip of every leg accommodates a ballast that extends to round 20 meters (65 ft) deep. These ballasts maintain tanks which can be largely crammed with contemporary water to maintain the platform afloat at a given top, however the higher a part of every tank additionally accommodates a 3- to 4-megawatt information corridor.
With three legs, a single platform might assist roughly 10-12 megawatts of computing capability, powered primarily by a 15-18 megawatt wind turbine mounted above it. Batteries built-in into the construction retailer extra power and easy out fluctuations in wind output. A grid connection will nonetheless function a backup, however the aim is to function largely off-grid, utilizing domestically generated renewable power.

The info facilities are tucked contained in the submerged legs of the construction, protected by metal and cooled by the ocean. Aikido’s system makes use of a passive major cooling mechanism that transfers warmth from the info facilities via the metal partitions of the ballast tanks and immediately into the encompassing seawater, with the corporate claiming the thermal impression on the ocean is proscribed to some meters across the construction.
One other benefit of this resolution is that, whereas the general idea is new, all of the techniques and applied sciences required to carry it to life exist already. Offshore wind, oil and fuel suppliers can manufacture the modular metal buildings at current fabrication websites, with the wind turbine, battery system, and 13 platform metal buildings shipped to the positioning prepared for integration. The info halls are additionally prefabricated onshore in a manufacturing facility setting, then lifted into place throughout remaining port-side integration.
Aikido expects the platform to attain a Energy Utilization Effectiveness (PUE) score of 1.08 because of its passive cooling system. For context, the global average PUE for information facilities hovers round 1.5, which means that for each unit of power used to energy the servers, one other 0.5 items are consumed by cooling and infrastructure overhead. A PUE of 1.08 is phenomenal, approaching the theoretical restrict of 1.0.

Quite than ranging from scratch on allowing or website identification, the corporate plans to construct on the groundwork already laid by the broader offshore wind trade. Aikido intends to make the most of the over 50 gigawatts of distressed floating wind websites globally that could possibly be repurposed instantly for sovereign information heart deployment.
“We now have this energy from the wind. We now have free cooling. We predict we will be fairly value aggressive in comparison with standard data-center options,” says Kanner.
The corporate plans to ultimately construct offshore wind farms able to supporting computing capability from 30 megawatts to greater than 1 gigawatt. For now, nonetheless, present realities are extra humble. Aikido’s first prototype, a 100-kilowatt unit utilizing a refurbished Vestas V-17 turbine, is scheduled to launch within the North Sea off the coast of Norway by the tip of 2026. The primary industrial challenge is focused for the UK, with a deliberate operational date of 2028. A website has already been recognized, and detailed engineering and industrial discussions are underway.
