Molslinjen has selected BOS Power to supply the two battery energy storage systems that will support its future electric high-speed catamarans on the Kattegat routes.
The supplier selection was carried out with technical support from Hybrid Greentech, which has advised Molslinjen throughout the project.
The two battery systems, located in Aarhus and Odden, will each have a capacity of 118 MWh. They will enable the ferries to recharge during 30-minute port calls by combining electricity from the grid with stored energy. Each ferry will charge at 15 kV AC and up to 55 MW, receiving approximately 25 MWh of energy before its next crossing.
The battery systems will also provide backup capacity, storing enough energy for three to four ferry crossings should the electricity supply be disrupted.
The three electric catamarans, currently under construction at Incat in Australia, are scheduled to enter service from spring 2028. The project is expected to become the world’s largest maritime electrification programme.
Once all three ferries are in operation, annual CO₂ emissions are expected to be reduced by 132,000 tonnes. The ferries and associated shore infrastructure represent a total investment of DKK 3.5 billion. The value of the battery storage contract has not been disclosed.
