Japanese consortium to build offshore green data centre in Yokohama, powered by renewable energy for AI-driven data processing.

Context

A Japanese consortium plans to develop an offshore floating data centre demonstration project off Yokohama’s coast. The group includes NYK Line, NTT Facilities, Eurus Energy Holdings , MUFG Bank , and the City of Yokohama. The initiative aims to address increasing data processing demands while overcoming land and energy limitations. The project will commence with a demonstration in autumn 2025 at Yokohama Port’s Osanbashi Pier. A 25-metre by 80-metre floating platform will host a container-based data centre, solar power systems, and battery storage. The trial will evaluate the energy efficiency, resilience, and environmental impact of this offshore model, focusing on resistance to salt damage and operational stability.

Evidence

Pending intelligence enrichment.

Analysis

Urban land constraints and power grid limitations present significant challenges. By moving data centres offshore, this project offers a potential solution. If successful, the initiative could lead to a network of offshore data centres near wind farms, providing direct access to clean energy and reducing reliance on onshore power infrastructure. This aligns with Japan’s GX2040 Vision to decarbonise and modernise energy-intensive industries.
