Corvus Energy to supply battery systems for new NYK electric tugboat

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.

Consortium validates grid-independent hydrogen power hub for ports

ELIRE Maritime and consortium partners on Monday (25 May) announced the successful completion of the UKRI-funded Clean Maritime Demonstrator Competition Round 6 (CMDC6) programme.

CMDC6 is a GBP 1 million (USD 1.3 million) feasibility programme and initiative delivered by Innovate UK in partnership with the UK Shipping Office for Reducing Emissions (UK SHORE), part of the UK Department for Transport.

The partners are Ricardo UK, Schneider Electric, Rux Energy UK, Triton Anchor Europe, OREC (Offshore Renewable Energy Catapult), and the University of Strathclyde. 

The programme successfully validated one of the world’s first fully grid-independent Hydrogen Floating Power Hub systems capable of delivering clean power directly to vessels at berth without requiring traditional shore-side grid infrastructure. 

The consortium demonstrated that large vessels can realistically be powered at berth today using existing hydrogen, battery, fuel cell, and electrical technologies integrated into a modular floating maritime system designed for rapid deployment across global ports.

The solution can now be deployed and would be expected to support the reduction of up to 500,000 tonnes of CO₂ emissions globally over the next decade through a scalable maritime clean energy infrastructure capable of operating independently from constrained port grids.

“Ports are under increasing pressure to decarbonise while facing major infrastructure constraints,” said Luke Jenkinson, Founder and CEO of ELIRE Maritime. 

“The Hydrogen Power Hub proves that ports do not need to wait years for grid upgrades to begin reducing emissions. We have validated a practical, scalable, and deployable system capable of delivering clean power directly where it is needed most.”

The Hydrogen Power Hub establishes a new category of maritime infrastructure by moving energy and power generation as well as storage onto water rather than relying on fixed, land-based systems constrained by grid access, cost, permitting, and land availability.

At full configuration, this particular validated system is capable of delivering 5MW of continuous clean power output directly to vessels at berth, enough to support medium-sized cruise vessels and other large maritime assets requiring both 6.6kV and 11kV shore power connections. This system integrates three modular hexagonal floating platforms with a combined 1,200 sqm footprint, approximately 45MWh of battery energy storage capacity, modular fuel cell systems, hydrogen-powered generation, onboard renewable generation, and advanced grid-forming AC/DC electrical architecture.

The consortium confirmed the platform can deliver approximately 91MWh of energy per week while supporting repeated vessel charging operations without requiring major civil works, land reclamation, or expensive grid reinforcement.

The system uses approximately 7,500 to 8,000kg of hydrogen weekly, stored within modular ISO-compatible low-pressure storage containers integrated directly into the floating infrastructure. The current layout accommodates seven onboard hydrogen tanks, with refuelling operations expected approximately twice weekly, enabling ports to adopt hydrogen incrementally without requiring permanent hydrogen infrastructure during early deployment phases.

Instead of relying on oversized generators, the platform uses modular 1.3MW fuel cells operating continuously throughout the week to gradually charge the onboard batteries before rapidly dispatching energy when vessels arrive at berth.

Wah Kwong NatPower backs Greater Bay Area zero-carbon shipping initiative

Wah Kwong NatPower Marine (WK NatPower), a joint venture between Wah Kwong Maritime Transport and NatPower Marine, on Wednesday (20 May) said it is supporting a new initiative to develop zero-carbon shipping routes across China’s Greater Bay Area, following a recent broader Memorandum of Understanding (MoU) with Guangzhou Port Group.

Under this MoU, WK NatPower will support maritime electrification by advancing the development of shore power infrastructure across Hong Kong, Greater China, and Asia. 

The initiative will focus on deploying electric vessels and establishing shore-side battery swapping and charging infrastructure across key ports in Guangdong province and Hong Kong, supporting the transition toward low-emission shipping operations.

WK NatPower will play a central role in developing a scalable electrification network, supplying clean electricity to vessels both at berth and for propulsion. The project aligns with China’s “dual carbon” targets and reflects broader efforts to integrate energy systems and port infrastructure at scale.

Guangzhou Port, a major international hub, is advancing its green port strategy through expanded shore power deployment and increased use of clean energy. The collaboration aims to establish standardised charging and battery-swapping infrastructure across the Greater Bay Area, enabling the development of integrated zero-carbon shipping corridors.

The partners will also explore the use of alternative marine fuels, including methanol and ammonia, as part of a broader decarbonisation pathway.

“Delivering zero-carbon shipping at scale requires alignment across ports, energy providers and shipping lines,” said Vincent Ni, General Manager of WK NatPower. 

“This initiative represents a significant step toward building the infrastructure needed to support electrified maritime operations across the region.”

WK NatPower is part of a broader strategy to develop a comprehensive maritime electrification infrastructure network across Asia, combining Wah Kwong’s maritime expertise with NatPower Marine’s global energy infrastructure capabilities.
