Norway's electric ferry build-out (2015 onward)
Norwegian operators put the first all-electric car ferries into regular service on short fjord crossings in 2015, using batteries charged at the dock. Public procurement rules on ferry routes drove the shift, and the country now runs the largest concentration of battery-powered ferries in the world.
Short crossings proved the case for all-electric operation where charging time fits the schedule.
More than 70 comparable vessels are in service in northern Europe, according to Washington's transportation department, and the technology became a standard option for ferry procurement.
Washington's ferries are modeled on this pattern: batteries for short routes and port maneuvers, diesel generators as backup until every terminal has charging.
