Nippon Yusen Kabushiki Kaisha (NYK Line), NTT FACILITIES, INC., Eurus Energy Holdings Corporation, MUFG Bank, Ltd., and the City of Yokohama entered into a memorandum of understanding (MoU) to conduct a demonstration project for an offshore floating green data center, according to NYK's release.
This initiative aims to utilize a mini-float (25 meters by 80 meters) installed off Osanbashi Pier in Yokohama City, Kanagawa Prefecture, to test a container-type data center powered entirely by renewable energy generated from solar power and battery storage systems.
The demonstration is scheduled to commence in autumn 2025.
The project seeks to assess the equipment's resistance to salt damage and operational stability in an offshore environment, with the broader objective of exploring further developments in Yokohama's waterfront and sea areas.
