China has launched the first all-electric cargo ship.
This 230 foot long vessel is equipped with a 2,400 kWh lithium-ion battery that stores enough electrical energy to transport 2200 tons of cargo a distance of 50 miles on a single charge at a top speed of about 8 miles per hour. Time to recharge the battery is 2 hours, which is approximately the time needed to unload the ship at its destination.
The ship was built at Guangzhou Shipyard International in Guangzhou, the capital of Guangdong province, which is located on the Pearl River north of Hong Kong. The shipyard is a wholly owned subsidiary of China State Shipbuilding Corporation.
This ship is fully electric powered so poses no threats to the environment. The technology will soon be used in passenger or engineering ships too. The battery for the ship is comprised of 1,000 individual lithium-ion packs. Adding enough power to carry more cargo is simply a matter of adding more battery packs.
The new ship has two primary benefits. First, it will emit no carbon emissions while underway. Cargo vessels tend to be some of the biggest carbon pollution sources in the entire transportation sector. Second, it will lower the cost of transportation for bulk cargoes because the price of electricity is lower than the price of diesel fuel.
