Maersk to introduce the use of batteries on container ships

DANISH shipping giant Maersk line is to install a containerised battery system on its 2011-built, 4,500 TEU container ship Maersk Cape Town with a capacity of 600kWh, which is equivalent to six Tesla cars.

The large battery to be housed in two containers is not powerful enough to propel the ship but will be used to complement the auxiliary engines. With the battery installed the ship's auxiliaries can be run more optimally. The battery can also be used as an emergency power source, according to London's ShipInsight.



Charging of the battery is done during sailing using a waste heat recovery system.



'We look forward to seeing the potential of the pilot project. Both in relation to what the battery technology can have for the improvement of the performance of our ships and not least the reduction of fuel consumption that goes for purposes other than operating the propeller,' said fleet technology manager at Maersk Line, Ole Graa.



'We hope that the project will give us a greater knowledge of energy storage, which will enable us to further electrify our fleet,' said a senior executive member of AP Moller-Maersk.



The new container battery system was assembled in Odense and is now in Aarhus before sailing to Singapore. The Maersk Cape Town will be sailing from Asia to West Africa over the next 3-4 months, and after evaluating the trial Maersk will be deciding whether to extend it to more ships.



'It's a really exciting project, and we welcome all initiatives that contribute to lowering CO2 emissions,' said Maria Skipper Schwenn, director of safety, environment and maritime research at Danish Shipping.
