Zero-emission solutions provider Corvus Energy on Thursday (30 October) said it has been selected to supply the battery systems for an electric tugboat, to be built by Japanese shipyard Keihin Dock for Nippon Yusen Kabushiki Kaisha (NYK Line).
The environmentally friendly harbour tug will be powered by Corvus Energy’s Orca Energy battery systems, with a total capacity of 2,712 kWh.
The concept design is led by the NYK Line, Project Engineering Team with further detail design finalised by Keihin Dock.
The new electric tugboat represents a major advancement in Japan’s efforts to achieve carbon-neutral ports. Equipped with batteries and Japan’s first domestically manufactured large-capacity motor drive system supplied by TMEIC Corporation, as well as a Dynamic Positioning System (DPS), the vessel will combine powerful zero-emission propulsion with enhanced crew comfort and safety.
“This vessel is the result of our collective innovation—a ‘Tugboat of the Future’ that cares for both people and the planet. It will lead the way in Japan’s next-generation maritime industry,” said Satohiko Kodama, Manager of Project Engineering Team at NYK Line.
“By integrating advanced electric propulsion from our domestic partners and state-of-the-art energy storage technology from Corvus Energy, we are taking an important step toward realizing zero-emission ports.”
“We are proud to collaborate with NYK and Keihin Dock on this innovative electric tug project,” said Ole Jacob Irgens, EVP and Head of Regional Sales for Europe and Asia at Corvus Energy.
“This project further strengthens Corvus Energy’s position as the leading provider of zero-emission battery technology in Japan, where more than ten vessels are already sailing with Corvus battery systems.”
The battery system will be supplied in partnership with Sumisho Marine and is scheduled for delivery in June 2026 and the tugboat is expected to begin operation by the end of 2026 under Naikai Tug Boat Service, part of the NYK Group company.
