Norway-headquartered Corvus Energy, a provider of zero-emission solutions for the maritime industry, will supply battery systems for an electric tugboat to be built by Japanese shipyard Keihin Dock for Nippon Yusen Kabushiki Kaisha (NYK Line).
The harbor tug will be powered by Corvus Energy’s Orca Energy battery systems, with a total capacity of 2,712 kWh. It will be equipped with a motor drive system supplied by TMEIC Corporation, as well as a dynamic positioning system.
The e-tugboat is expected to begin operation by the end of 2026.
“This Tugboat of the Future 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.”
“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,” said Ole Jacob Irgens, Head of Regional Sales for Europe and Asia at Corvus Energy.
He added: “Batteries are ideally suited for tugboats because they enable zero-emission operations during idling and low-power maneuvers, so diesel engines are needed only when maximum thrust is required. This hybrid approach significantly reduces fuel consumption, emissions, noise and maintenance while enhancing efficiency and responsiveness. We strongly believe energy storage will become the standard for all tugs going forward.”
