Japanese consortium bets on building bobbing bit barns

A Japanese consortium has set its sights on addressing the burgeoning datacenter space crunch by proposing to construct floating data centers, anchored safely alongside port quays. The consortium consists of shipping and logistics giant NYK Line, engineering firm NTT Facilities, renewable energy company Eurus Energy, and MUFG Bank.

They have also considered offshore options, where facilities could harness renewable energy sources like offshore wind power, similar to efforts by Oregon-based Panthalassa. However, the consortium acknowledges the practical challenges of offshore deployments, such as access for maintenance, high-capacity telecom links, and independent power supplies.

To overcome these hurdles, they plan to initially deploy floating facilities alongside quays, utilizing existing port infrastructure and nearby power generation facilities until they are prepared to expand beyond the coast.

The consortium believes that floating bit barns could help meet growing compute demands without encroaching on limited development land. They still require a means to connect these facilities to the power grid. The consortium members will each assume specific roles in the development process. NYK Line will oversee development, NTT Facilities will handle design, construction, and operation assessments, Eurus Energy will explore renewable power supply options, and MUFG Bank will consider financing for these ventures.

The team has already signed a memorandum of understanding with Yokohama city for a renewable-powered demonstration project at the port, with testing beginning in March. The consortium may face competition from other players in the floating data center market, with Samsung Heavy Industries aiming to launch its first facility by the second quarter of 2028.
