Global fleet of battery-powered ships tops 2,000 vessels, marking decarbonisation breakthrough

The Maritime Battery Forum’s ship registry shows that the global fleet of battery-powered commercial vessels has crossed the 2,000-ship threshold, amounting to 2.4 GWh of maritime battery capacity. Syb ten Cate Hoedemaker says the technology is now ready for large-scale deployment thanks to falling battery costs. The fleet is diverse: 68% are hybrids, 13% plug-in hybrids and 18% fully electric, covering passenger, offshore, cargo, fishing and workboat categories.

Europe, led by Norway, accounts for most recorded ships, while the registry lists only a small slice of China’s actual numbers. Experts warn that market momentum alone won’t achieve full decarbonisation; the UN’s International Maritime Organisation is set to adopt a Net-Zero Framework in December, which they argue is vital for broader adoption.
