The relentless demand for energy to power the artificial intelligence boom is driving innovation in data center infrastructure. While some companies are looking to space for solutions, California-based Aikido Technologies is proposing a different approach: submerging data centers beneath floating offshore wind turbines. This novel concept aims to address the growing energy consumption of AI and reduce the strain on traditional power grids by co-locating compute power with renewable energy generation.
Aikido Technologies unveiled plans this week to house data centers within the underwater ballast tanks that stabilize its floating turbine platforms. The company envisions systems capable of hosting 10 to 12 megawatts of AI compute alongside a 15 to 18 megawatt turbine, integrated with battery storage. “Before we go off-world, we should go offshore,” said Sam Kanner, CEO of Aikido Technologies, in a statement. The company plans to test a 100-kilowatt prototype off the coast of Norway later this year, according to IEEE Spectrum.
Traditional data centers consumed 183 terawatt hours of electricity in the U.S. In 2024, accounting for 4% of the country’s total electricity consumption. If current expansion rates continue, that figure could more than double by 2030. Aikido’s approach seeks to mitigate this growing energy demand and carbon footprint by directly integrating data centers with a sustainable power source.
How Aikido’s Offshore Data Centers Would Operate
Aikido’s system utilizes a large platform supporting a central turbine, with three legs extending downwards. The ends of these legs feature ballast tanks reaching 66 feet (20 meters) deep. These tanks, primarily filled with fresh water for buoyancy, will also house 3 to 4 megawatts of data center capacity in their upper sections. This design offers a dual benefit: proximity to power and an efficient cooling solution.
The ocean itself will serve as a natural “infinite heat sink.” Aikido plans to employ a passive cooling system, transferring heat from the data centers through the steel walls of the ballast tanks and into the surrounding seawater. The company claims the thermal impact on the ocean will be limited to a few meters around the structure. Aikido aims to scale these systems to support 30 megawatts to over 1 gigawatt of compute capacity, meeting the escalating demands of AI infrastructure.
Not Alone in Exploring Novel Data Center Locations
While Aikido’s approach of integrating data centers directly into offshore wind infrastructure appears unique, the company isn’t the only one exploring unconventional locations for data centers. Other companies are investigating underwater facilities, floating buoys, and even repurposed coal mines. This surge in creativity is driven by rising energy demands, the need for domestic renewable power, and limited available real estate, as noted in a report from AOL.
WestfalenWind-Group in Germany is also pursuing a similar concept, though onshore. The company’s windCORES project is deploying data centers directly into the towers of its wind turbines.
Challenges and Opportunities for Offshore Compute
Despite the potential benefits, Aikido faces hurdles. The floating offshore wind sector is currently experiencing developmental delays, rising costs, and the impact of diminishing government subsidies. Kanner acknowledged these challenges, telling Data Center Dynamics that Aikido hopes to revitalize the sector by presenting a more compelling business model.
Technical challenges also exist. Daniel King, a research fellow at the Foundation for American Innovation, pointed out potential engineering difficulties related to the corrosive ocean environment and the impact of debris on infrastructure. He also highlighted potential regulatory hurdles related to protecting marine life from thermal discharge, as reported by IEEE Spectrum.
Prototype testing will be crucial in determining the feasibility of Aikido’s vision. However, the company’s innovative approach represents a promising step towards more sustainable and efficient AI infrastructure. The success of this project could pave the way for a new era of offshore data centers, offering a viable solution to the growing energy demands of the AI revolution.
The coming months will be critical as Aikido prepares for its prototype launch off the coast of Norway. The results of this initial test will provide valuable insights into the technical and economic viability of offshore data centers and their potential to reshape the future of AI computing.
