Corvus Energy on Wednesday (30 November) said participation in the innovative Crowley eWolf zero-emission tugboat project has expanded with an order to supply shoreside battery energy storage systems (ESS) using two Corvus Orca BOBs—the containerised version of its market-leading Corvus Orca ESS—with a total energy storage capacity of 2,990 kWh.

The Crowley eWolf, the first all-electric tug in the U.S., and its shoreside charging infrastructure will go into service in San Diego’s harbor in 2023. Corvus Energy also supplying the 6.2 MWh Corvus Orca ESS on board eWolf. The vessel is under construction at Master Boat Builders, with electrical integration provided by ABB.

“The use of the Corvus Orca ESS shoreside will allow eWolf to charge quickly, potentially avoiding the need to upgrade the electricity grid infrastructure at the port,” remarks Ole Jacob Irgens, Corvus Energy – President Americas. “Since the Orca ESS has a high C-rate, it is capable of discharging quickly and safely so that eWolf will be quickly recharged and returned into service.”

The eWolf and the shoreside infrastructure are designed to allow the vessel to operate fully electric with full performance capabilities, as well as draw energy at off-peak hours from the energy grid. The eWolf is a result of a partnership among Crowley, the San Diego County Air Pollution Control District, the California Air Resources Board, the Port of San Diego, the U.S. Environmental Protection Agency and the U.S. Maritime Administration, which all provided financial support and other resources. 

“Corvus Energy’s storage system will enable Crowley and our federal, state and local partners to reach our shared commitment of reducing emissions and providing cleaner air for the San Diego community. The innovative technology also will help ensure high performance and reliability as the tugboats serves customers – providing a model for sustainability at ports around the nation,” said Paul Manzi, vice president, Crowley Shipping.

Battery energy storage a viable alternative shoreside energy

The eWolf and its shoreside energy technology are examples of innovative maritime sustainability opportunities to help decarbonize the maritime industry. Crowley and Shell Trading (US) Company (Shell) have signed a memorandum of understanding (MOU) focused on supporting alternative energy solutions for shoreside and terminal operations. The Corvus Orca BOB shoreside battery energy storage system reflects this commitment.

“We recognise that the world is in the midst of an energy transition, and we’re working hard to play our part,” said Maarten Poort, general manager of Shell Shipping & Maritime Americas. “As both an investor and customer of Corvus Energy and its innovative ESS products, Shell is proud to support battery energy bunkering as a zero-emission alternative energy solution for shore power.”

Corvus Orca BOB plug-and-play battery room

The Corvus Orca BOB containers will each contain almost 1.5 MWh of energy storage capacity and be capable of “fast-charging” the Crowley eWolf tug. The Corvus Orca BOB is a class-approved, modular battery room solution in standard 20-foot ISO high-cube container size. The complete ESS comes with Orca battery modules, battery monitoring system (BMS), HVAC , TR exhaust, and firefighting and detection system. The “Plug and Play battery room” simplifies integration into any system integrator’s power management system on board a ship.

Seaspan and Hapag-Lloyd complete first of five methanol vessel retrofit

Seaspan Corporation (Seaspan) and Hapag-Lloyd on Wednesday (3 June) announced the successful completion of the first of the five vessel conversions under their methanol retrofit programme with the delivery of Seaspan Yangtze.

From the early SAVER (Seaspan Action for Vessel Energy Reduction) programme to today’s CleanBlue initiative, Seaspan has committed over USD 230 USD million across 86 vessels, executing more than 550 efficiency and retrofit projects.

Following Seaspan Yangtze, the remaining vessels planned for retrofit under the programme are Seaspan Amazon, Seaspan Ganges, Seaspan Thames, and Seaspan Zambezi. Each retrofit is expected to reduce well-to-wake CO₂e emissions by approximately 30,000 to 50,000 metric tonnes per vessel annually when operating on low-carbon methanol, while also extending vessel lifespan and enhancing fuel flexibility.

“Decarbonisation is not just about building the fleet of tomorrow, it is also about unlocking the full potential of the fleet we have today. Retrofitting and upgrades on existing fleets play a practical, immediate, and economical role in accelerating shipping’s decarbonization journey,” said Bing Chen, Chairman, President and CEO of Seaspan. 

“Project SAVER CleanBlue highlights Seaspan’s strong customer partnerships, deep technical expertise, and unique platform integrated with JV partners, such as WattSpan Maritime Technology, in executing complex and large-scale retrofit projects.”

“The successful conversion of the Seaspan Yangtze together with the planned retrofit of its four sister vessels is another important step on our ambitious path towards net-zero fleet operations by 2045,” said Silke Lehmköster, Managing Director, Fleet, Hapag-Lloyd. 

“Together with Seaspan, we are demonstrating that retrofitting existing vessels for low-carbon methanol can be a practical way to reduce emissions in shipping.”

South Korean-led nuclear car carrier design secures LR backing

Classification society Lloyd’s Register (LR) on Tuesday (2 June) said it has teamed up with South Korean shipbuilding, marine services and nuclear research organisations to advance the development of a nuclear‑assisted car carrier concept. 

LR is working with Hyundai Heavy Industries, Korea Shipbuilding & Offshore Engineering (KSOE), Hyundai Glovis, G- Marine Service and the Korea Atomic Energy Research Institute (KAERI) on a joint development project (JDP) exploring an advanced small modular reactor (SMR) installation on a pure car and truck carrier (PCTC). 

The study focused on how a Molten Salt Reactor (MSR) could be physically and operationally integrated into a large vehicle carrier. Work examined the internal arrangement and segregation of the reactor system, shielding requirements, and the impact on cargo deck layout and vehicle capacity, alongside stability and trim implications linked to the reactor’s weight and positioning. 

The partners also assessed propulsion system configuration and power delivery, as well as operational flexibility compared with conventionally fuelled PCTCs, where trade routes and port calls can be tightly constrained. 

A key focus of the project has been safety. LR led hazard identification (HAZID) and preliminary risk assessment work, focusing on containment, onboard safety systems and potential operability constraints tied to nuclear technology at sea. 

The partners will mark the project milestone with an Approval in Principle (AiP) granting ceremony on 2 June at the LR stand during Posidonia 2026. 

Sung-Gu Park, President – North East Asia, Lloyd’s Register, said: “While nuclear propulsion is still at an early stage of development, this project shows the importance of building technical understanding now to support future progress. 

“Establishing feasibility at concept stage is a valuable step forward, particularly in areas such as cargo optimisation, vessel stability and integrated safety design.” 

Hong-Ryeul Ryu, CTO and Senior Executive Vice President at HD HHI, said: “With global environmental regulations becoming increasingly stringent and no definitive net-zero fuel yet available, SMR-powered ships can serve as a highly effective alternative, representing a pioneering next-generation maritime technology capable of complying with GHG emission regulations while allowing lifetime operation without refuelling, and HD HHI will remain at the forefront of sustainable maritime technology development.”
