Echandia to supply battery system for a second emission-free high-speed catamaran

Swedish Echandia, a leading developer of heavy-duty energy solutions for maritime electrification, has received a second order from Green City Ferries AB. Green City Ferries is expanding its waterborne public transport in Stockholm with another ambitious zero-emission Beluga24 vessel. The Beluga24 is the world’s first fully emission-free, high-speed, carbon fiber catamaran, and Echandia has been chosen to provide energy solutions for the vessels. The order is worth approximately SEK 7.5 million.Late last year, Echandia announced its first order for a fuel cell energy solution to power the first Beluga24 vessel from Green City Ferries. Now we can announce that Echandia has also been appointed to supply highly specialized battery energy storage solutions for the second vessel.

Battery power abates fossil fuels

The recently signed order for the battery vessel with its 730-kWh installation, is optimized for high-speed commuting with charging points on both ends of the route. At 30 knots, energy consumption is estimated to be nearly half of diesel-powered catamarans of the same size and performance. In total, the battery powered vessel on this route will abate 2000 ton of CO2 annually.With its capacity of 147 passengers and 28 bikes, it will be as low as 0.2 kWh per nautical mile, per passenger.Green City Ferries has previously announced two routes in Stockholm, Sweden. By 2024, the plan is to commission one fully electric vessel between Täby and Ropsten, and one powered by an integrated battery and hydrogen-based fuel cell system in the archipelago of Österåker. The vessel for the latter route is co-funded by the European Union through the project TECOW (

Waterborne transport is about to change

The maritime industry is currently undergoing the same transformation as the automotive industry but realizing fully battery-powered high-speed vessels is a significant technical accomplishment.Maritime applications are more demanding than electric vehicle applications and are dramatically raising the bar in terms of durability, life cycle, and safety.
Echandia’s battery and fuel cell systems are significantly smaller than competing systems due to their high energy efficiency and life cycle performance, making them suitable for heavy duty profiles where space and weight are limited.Sweden is now picking up pace in maritime electrification and this is an important step in the right direction. This project not only reduces emissions from Stockholm’s waterways, but also pioneers emission-free high-speed transportation that potentially can be used in cities all over the world.

Echandia’s battery solutions really fits well for these demanding operational profiles with high-power needs and uninterrupted service over long periods of time. We are honored to be trusted as a part of Green City Ferries’ breakthroughs in maritime transportation. Their project, which not only reduces emissions from Stockholm’s waterborne local transportation but also pioneers emission-free high-speed catamarans that potentially can be used in cities all over the world.

The introduction of Beluga24 in Stockholm is a significant step toward lowering carbon dioxide emissions from the region’s waterborne public transportation system. Echandia’s energy solutions are critical to realizing the ground-breaking emission-free high-speed passenger commuting concept. We can now demonstrate that there is an appealing alternative to traditional vessels for both shorter and longer routes.
