A Japanese shipbuilding company named IHI Marine United is developing a ship that can be powered entirely by rechargeable lithium batteries. It will be able to travel 80 km while carrying 800 passengers:

Its Zero Emission Electric Propulsion Ship will use batteries that can be recharged at charging stations in ports it visits. The plug-in ship powered by lithium-ion batteries would run without a diesel engine, thus cutting its carbon dioxide or nitrogen oxide emissions to zero.

The company hopes to have a commercial vehicle available in 2015.
