There are currently more than 600 ships globally with batteries installed as part of the propulsion system. Although this is only a fraction of the global fleet, the installed battery capacity on board of ships is increasing rapidly. Although 2021 showed a small dip in the installed capacity on board of ships, for 2022 so far at least 180 MWh is predicted to be installed.
Although the majority of ships that use large battery systems for propulsion are ferries, the maritime industry is discovering that batteries can be used for all kinds of vessels. Currently, about 25% of the battery powered ships are only powered by batteries, another 25% are plug-in hybrid, and the remaining 50% are hybrid without the posibility to charge them with a shore based charging system. With an average installed battery capacity of 1.2 MWh in 2022, and this is expected to increase further, the required charging power for ships is often in the MW range. The Megawatt Charging System (MCS) is expected to accelerate the adoption of MW charging in the maritime sector, increasing the number of plug-in hybrids compared to hybrid ships, which will be a major step in the reduction of emissions in and around ports.
Information about Maritime Battery Forum
The MBF is a non-profit organization promoting batteries in the maritime industry by sharing knowledge and information. The MBF has currently 55 members ranging from maritime battery manufacturers, shipyards, shipowners, integrators, class societies, research institutes, to all other companies who want to be involved in the discussion on how to further develop battery technology in the maritime industry . Through collaboration projects, the members work together on a global understanding of the challenges with batteries on board of ships and set the standard for rules and regulations. The MBF also maintains a Ship Register providing an overview of all battery powered ships around the world.
