LECLANCHE SA, a world-leading provider of energy storage solutions is proud to announce that it has officially commenced serial production of its latest marine energy storage system, the Navius MRS-3, at its Yverdon-les-Bains, Switzerland facility.
Developed to meet the growing demand for sustainable, high-performance marine propulsion, the Navius MRS-3 is Leclanché’s most advanced marine rack system to date. It delivers industry-leading energy density and safety, along with a modular architecture that ensures seamless scalability across a wide range of vessel types – from ferries and cruise ships to offshore supply and cargo vessels.
“The launch of serial production marks a significant milestone, not only for Leclanché but for the maritime industry as a whole,” said Guillaume Clément, Vice President of E-Marine at Leclanché. “The Navius MRS-3 is the result of years of development and testing. Its performance, flexibility and certified safety standards make it a future-ready solution for operators seeking to decarbonise their fleets. We’re proud to bring it to market at scale.”
Certified by Lloyd’s Register (LR), Bureau Veritas (BV) and DNV, the Navius MRS-3 complies with the latest marine safety and performance standards. Its production at Leclanché’s Swiss-based facility benefits from high levels of automation and quality control, ensuring consistent manufacturing at scale.
With the maritime industry under increasing pressure to reduce greenhouse gas emissions, battery systems such as the Navius MRS-3 play a crucial role in enabling hybrid and fully electric vessel propulsion. As a vertically integrated company, Leclanché designs and produces its own lithium-ion cells, modules and battery management systems – offering a complete, high-integrity energy storage solution for marine applications.
