The emission-free and safe energy supply is provided by a 6.7 MWh battery system with integrated liquid cooling to ensure optimum operating temperature. The Leclanché Marine Rack System (MRS) ensures optimum temperature control of the cells and their permanently reliable operation over a service life of at least 10 years. In addition, the MRS offers state-of-the-art protection against overheating and an integrated fire protection system specifically designed and certified for maritime requirements.
The Yara Birkeland has completed its maiden voyage to Oslo in mid-November and then sailed on to Porsgrunn, the southern Norwegian production site of Yara International, a fertiliser manufacturer and the vessel owner.
Leclanché supplied a 6.7 MWh battery system (which represents the same energy as 130 Tesla Model 3 batteries) for the energy supply of the approximately 80 meters long and 15 meters wide container ship with a deadweight of 3,120 tonnes or 120 standard containers (TEU). This electrically powered “green vessel” will operate at a service speed of approximately 6 knots, with a maximum speed of 13 knots.
Lithium-ion battery system – made in Europe
The battery system of the Yara Birkeland, manufactured in Switzerland, is fitted with lithium-ion cells which are produced at Leclanché’s automated production facility in Willstätt, Germany and battery modules made in Switzerland. The high energy density cells combined with long life cycle of 8,000 @ 80% DoD, with operating temperature ranges from -20 to +55°C, are at the core of the battery system. This Leclanché Marine Rack System consists of 20 strings with 51 modules of 32 cells each, for a total of 32,640 cells. The battery system has built-in redundancy, with eight separate battery rooms: if multiple strings are emptied or stop working, the vessel can continue its operations.
When it comes to battery systems for marine applications, efficient protection against overheating is indispensable. To prevent a fire on the open sea, Leclanché specially developed the modular DNV-GL certified MRS. Each battery string contains gas and smoke detectors, redundant thermal monitoring and a cooling system to prevent overheating and thermal incidents. Should a thermal incident occur despite all this, the Fifi4Marine fire extinguishing system kicks in: based on environmentally friendly foam, it cools and extinguishes quickly and effectively.
Zero emissions thanks to battery drive
Once the test period is completed, the Yara Birkeland will navigate on a completely autonomous basis transporting containers products from Yara International’s production plant in Herøya to the port of Brevik. Yara International is pursuing a zero-emission strategy with the all-electric drive solution: the vessel’s operation will displace around 40,000 truck journeys per year and the associated NOx and CO2 emissions. It also reduces noise and air pollution while in port. The batteries are charged automatically with electricity from renewable sources.
e-Marine at Leclanché
Sustainability is an important and serious business and cultural commitment for Leclanché. All of the Company’s products and its sustainable production methodologies allow it to make an important contribution to the e-mobility industry and the global energy transition to sustainability. Leclanché is one of the few European battery system suppliers that has its own cell production facilities and the complete know-how to produce high-quality lithium-ion cells — from electrochemistry to battery management software and an array of battery systems. The systems are used in stationary energy storage systems, trains, buses and ships, among others. The e-Marine sector is currently Leclanché’s fastest growing business segment. The company has already delivered battery systems for multiple ships with electric or hybrid propulsion systems with orders for many more. Among the projects successfully completed is “Ellen,” a passenger and vehicle ferry which has been operating in the Danish Baltic Sea since 2019 and is the longest range, all-electric ferry in daily operation.
