Fixed Routes Make Passenger Ferries a Practical Test for Battery Shipping

Bloomberg’s report argues that passenger ferries are among the most practical ships to electrify: fixed routes and predictable port calls make it easier to calculate battery needs and recharge between trips. The case is illustrated by China Zorrilla, a 130-meter ferry under construction with more than 40 megawatt-hours of battery capacity, though its costs and the charging infrastructure it requires remain significant hurdles. The report presents ferries as a proving ground for battery propulsion, not a model for long-distance ocean shipping.
