I did a review awhile back on various low carbon shipping options. Its interesting to note that the one option I didn’t consider was pure electric boats. This is largely because of the range issue. The idea of electric boats, isn’t anything new, they’ve been since the 1880’s, only falling out of fashion with the development of petrol powered outboard motors in the 1920’s.
However the Norwegians are now proposing the use of electric ferries around the country.
