Leclanché will use the MRS on Denmark’s E-ferry, a 100 per cent electric ferry by battery capacity; it will be equipped with a 4.3 MWh Leclanché Lithium-ion battery and scheduled for launch later this year. It will sail between the island Aeroe (Ærø) and the mainland. The emission-free, passenger and car ferry will be able to sail a record 60 nautical miles (110 km) on a single charge, according to Leclanché. The E-ferry is an EU Horizon 2020 project, the EU's €77 billion transport and energy research and innovation programme operational from 2014 to 2020. 

Anil Srivastava, CEO of Leclanché, said: “There is a huge opportunity for marine vessels across the world to reduce their harmful emissions and cut their operating costs by leveraging battery storage technology.” 

Leclanché  predicts that in Scandinavia, there is the potential to convert nearly 200 ferry routes to electric within the next decade; Europe-wide over 1,000 ferries could be converted. “The Leclanché MRS could also be used in other marine applications including hybridization and peak shaving of auxiliary loads of cargo vessels and cruise ships. In 2015 the global marine hybrid propulsion market was valued at US$2,6bn. It is expected to reach US$5,2bn by 2024, representing a CAGR of 8.2 per cent from 2016 to 2024”.
