A new ferry service may soon link Scotland and France again. The port of Dunkirk, now starting a €40bn regeneration plan, aims to launch a ferry between Rosyth in Fife and Dunkirk later this year. This will be the first passenger ferry on the route in 16 years. Freight ferries stopped eight years ago. The large upgrade of Dunkirk port includes new low-carbon energy projects and battery factories. Patrice Vergriete, Dunkirk's mayor, says the plan focuses on "energy and ecological transition" to revive the industrial region. Dunkirk, famous for the WWII evacuation, is transforming from old heavy industries to modern green businesses. The port has already secured about €4bn in investments. French company Verkor opened a car battery factory here in December. It also partners with Renault to develop hydrogen fuel cars. Steelmaker ArcelorMittal is switching its factories to cleaner electric arc furnaces with €850m in French support. A big focus is cleaning and redeveloping a former refinery site into factories making batteries and biofuels. New import-export terminals and a €25m rail terminal will cut truck traffic and help reduce carbon emissions. The proposed ferry to Scotland would run three times a week, taking around 20 hours from Rosyth. Danish company DFDS may operate the route. New facilities for post-Brexit border checks are planned, with inspections possibly done in Grangemouth, 20 miles from Rosyth. Daniel Deschodt from Dunkirk port said the route could attract Scottish rugby fans attending events like the Six Nations. Besides Scotland, Dunkirk plans new routes to the Nordics and South America. Currently, one in four French bananas and pineapples come through Dunkirk from Colombia. The port also aims to build a carbon capture hub to support European industry, possibly linking with Scotland. This ferry service revival marks a fresh link between Scotland and mainland Europe after a long break, joining Dunkirk's bold industrial comeback.
