Five smaller and six large container ships are under development in the Netherlands using €7 million in subsidies from the European Union.

The first barge is expected to start service in August. Because of the size of batteries, these vessels are being called Tesla-ships (the capacity remains undisclosed).

Specs for the smaller ships:

52 metres long and 6.7m wide
can carry 24 20-foot containers weighing up to 425 tonnes
single 20-foot battery for 15 hours of operation
Spec for the larger ships:

110m long
can carry 270 containers
four batteries for 35 hours of operation
