Norway is a leader in the development of clean transport, especially maritime. They have been experimenting with autonomous ships for several years.
Here are two new ships, which will not operate autonomously at the start, but will sail with a crew of 4. However, the goal is to test the systems for two years, and become autonomous after that.
They will transport products for a grocery along the coast of Norway. There is a plan for an all-electric corridor, including these ships and a fleet of electric trucks for the start and end parts of the trip.
