Powered entirely by batteries, Ellen is something of a Tesla among ferries. Fully charged, the 60m vessel can sail 22 nautical miles with up to 200 passengers and 30 cars onboard.
[...] Totalling 4.3MWh this is the largest battery capacity at sea and equivalent to the average amount of electricity a UK household consumes each year.
[...] After a 70 minute voyage, Ellen arrives at the harbour in Søby and moors alongside the charging station.
A mechanical arm plugs in and recharges the batteries in less than 25 minutes with clean energy supplied by local wind turbines.
[...] "We are paying maybe 25% of what you would pay for running a similar diesel vessel." says Ms Heinemann. "So that's the significant saving."
Electric propulsion is beginning to spread from passenger cars to trucks and now ferries.

A more practical (and greener) solution would be to take advantage of wind power by placing a sail on the boat and using the batteries onboard as a power assist to blow a fan into the sail.
