The world's first 2,000-metric-ton electric boat was launched Sunday in the southern city of Guangzhou.

With a battery capacity of 2,400 kilowatt-hours, the self-unloading ship built by Guangzhou Shipyard International has zero exhaust emissions.

The ship is powered by lithium battery and super capacitor, and can last up to 80 kilometers after a two-hour recharge.

The steel cargo ship will be used to carry coal and it will navigate on the Pearl River and other bodies of water.
