Electric Boats & Ships: Five Key Battery Suppliers, Identifies IDTechEx
Swiss battery-maker is the only vertically integrated company in this list, having been founded in 1909 to produce dry cells and today supplying industries ranging from electric vehicles to robotics. However, the company is relatively new to the maritime sector and today is an important player, pushing the envelope with megawatt-scale projects. The e-ferry 'Ellen' was the first project which drove Leclanché into the sector: a pure electric ferry with a 4.3MWh battery and 4MW charging capability. The project started on June 1, 2015 , and came into service in 2020, costing 30 million euros ( $35.7 million ) to build. It operates in the Danish part of the Baltic sea over a one-way distance of 10.7 nautical miles (19.8km). Leclanché is currently working on the Yara Birkland, a 6.5MWh project which is planned to be the first autonomous bulk carrier vessel. Estimated annual maritime installations are ~12MWh.
was founded in Norway in 2009 by Dr. Jan-Olaf Willums , a former director at Volvo and a green investor. Although a small local player, ZEM has access to one of the largest electric ferry markets in the world: by 2022 ~40% of all ferries are expected to be hybrid or electric in Norway . In June 2021 , ZEM was acquired by Volvo Penta, which makes diesel and electric propulsion systems for vessels, a partnership that will help both sides grow electric maritime installations. Estimated annual maritime installations are currently < 10MWh.
was founded in 2009 in the Netherlands and supplies battery modules branded Green Orca. These are based on NMC pouch cells from premium battery maker Kokam; the cells have a proprietary internal design called 'Z folding', different from typical winding or stacking techniques. EST is in second place to Corvus with a track record of more than 100 successfully installed systems, mostly small-scale with an average size of ~30kWh. EST is growing rapidly as the European electric vessel market is accelerating and is well-positioned to capture market share by supplying electric ferries, waterbuses, inland barges, and finishing vessels. Estimated annual maritime installations ~15MWh.
was formed in 2013 by several Dow Kokam employees and released its first maritime product – Trident – in 2018. Its initial projects served the North American market, but it has since expanded with a European production facility in Brussels . The company's USP is a military-grade liquid-cooled system, which uses NMC cells. The liquid cooling adds only 3% extra weight for a fractional $ per kWh cost increase. This allows SPS to pass cell-to-cell thermal propagation tests, in contrast to module-to-module tests more typical for class compliance. Estimated annual maritime installations < 10MWh.
