Designing an electric cargo ship isn’t as easy as making an electric car—and until recently, most experts would have argued that battery-electric ships weren’t feasible for traveling across oceans. A giant cargo ship might theoretically need a battery that weighs 1.6 billion pounds, more than the ship could carry. But one startup plans to soon begin crossing the Pacific with smaller electric ships that swap batteries at ports along the way, in a system that it says could prove cheaper than shipping with fossil fuels.
