Corvus Energy, the world’s leading provider of zero-emission energy solutions for the maritime industry, has been awarded a record-breaking order by Remontowa Shipbuilding in Poland. The order is for the supply of advanced battery systems for seven new fully electric ferries commissioned by Caledonian Maritime Assets Limited (CMAL), owned by the Scottish Government.
This marks the largest contract in Corvus Energy’s history, measured in USD value, and represents a significant milestone in advancing clean, sustainable ferry operations in the UK.
“It’s truly remarkable to witness seven identical ferries being constructed at the same shipyard,” says Stein Ruben Larsen, Senior Vice President of Sales at Corvus Energy. “This project is significant for Corvus Energy not only because of its scale, but also because of the outstanding collaboration we’ve had with the designer, the shipyard, and the integrator throughout the entire process.”
The order forms part of CMAL’s ambitious plan to deliver seven new Loch-class electric ferries under its Small Vessel Replacement Program (SVRP) — an initiative aimed at reducing emissions, modernizing the fleet, and improving connectivity across Scotland’s Island communities. By joining this national effort to decarbonize transport, Corvus Energy reinforces its position as a trusted technology partner in the global transition toward zero-emission operations.
Each of the seven new car and passenger ferries will be equipped with 5.7 MWh Corvus Dolphin NxtGen Energy Storage Systems, representing a total capacity of 40 MWh. Corvus Energy will deliver the first system in 2026, followed by three in 2027 and another three in 2028.
The vessels are the result of international collaboration: naValue (Germany) provided the concept design, LMG Marin (Norway) developed the basic design, and Remontowa Marine Design & Consulting (Poland) contributed the electrical and detailed design. Integration will be carried out by ABB.
Operating along Scotland’s west coast, these ferries will provide vital transport links for local communities while achieving zero-emission operations, marking a significant step forward in sustainable maritime transport.
The contract builds on a long-standing collaboration between Remontowa Shipbuilding and Corvus Energy, which began in 2018. Over the years, Corvus has supplied battery systems via integrators to several of Remontowa’s newbuild projects — including both fully electric ferries and hybrid offshore vessels. Including the seven Caledonian Maritime Assets Limited newbuilds, the total number of joint projects is close to 20, demonstrating the continuity and cooperation between the two companies in developing zero- and low-emission vessel solutions.
“Remontowa Shipbuilding is pleased to continue our cooperation with Corvus Energy on these vessels,” says Michal Jaguszewski, Commercial Director at Remontowa Shipbuilding S.A. “Our collaboration has proven reliable through multiple projects, and Corvus’ light weight ESS technology plays an important role in achieving the high environmental standards required for CMAL’s new ferries.”
“It is truly rewarding to see our long-standing partnership with Remontowa continue into such a significant project. Since 2018, we have collaborated on a wide range of vessels, building a foundation of mutual trust that we deeply value. This contract also marks the conclusion of a fantastic year for Corvus Energy, with record-high order intake and revenue. As we look ahead to a market in strong growth, we are excited to support the yard in delivering these state-of-the-art electric ferries and grateful that so many customers continue to choose Corvus solutions.” – Fredrik Witte, CEO of Corvus Energy
