China Launches World’s First All-Electric Cargo Ship, Will Use It To Haul Coal
Here’s the good news: China has launched the first all-electric cargo ship. According to China Daily, the 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 given as 2 hours, which is approximately the time needed to unload the ship at its destination.

Here’s the bad news: The all-electric cargo ship will be used primarily to transport coal to generating stations along the Pearl River. So, imagine this — the world now has a ship that can claim to be zero emissions even though it is powered by electricity generated by burning coal, one of the dirtiest of fossil fuels in terms of carbon emissions, and is used to transport coal more cheaply.
