Danish container line Maersk is to trial a battery in a box system to cut CO2 emissions.

The company said the containerised 600 kWh marine battery kit will be installed on the 4,496-teu Maersk Cape Town (built 2011) next month to improve performance and reduce its carbon footprint.

“This trial will provide a greater understanding of energy storage that will support Maersk in moving towards further electrification of its fleet and port terminals.
