A containerized 600 kWh marine battery system will be installed in a trial on board of the container ship »Maersk[ds_preview] Cape Town« in December to improve vessel performance and reliability while reducing CO2 emissions. According to Maersk, by maintaining the vessel’s auxiliary generators at a more optimal load, and avoiding running generators when not needed, overall fuel consumption can be reduced. Additionally, it will support the generators with up to 1,800 kVA of power during rapid changes in electrical load such as thruster operation. This can reduce generator maintenance requirements. The battery system is also capable of providing redundant power, which can improve reliability at sea by ensuring continuous power supply.
