Maritime transport is one of the sectors which pollutes the most. To decarbonize as much as possible, sailing ships are emerging. The cruise ship of tomorrow was unveiled on Friday 3 December at the Chantiers de l’Atlantique in Saint-Nazaire (Loire-Atlantique).
50,000 commercial vessels sail on all the seas of the world. Monsters of steel, big consumers of heavy fuel oil, one of the dirtiest fuels in the world. Faced with this observation, a mode of maritime transport has reappeared: the sailboat. At the Atlantique shipyards in Saint-Nazaire (Loire-Atlantique), we have been relying on wind energy for 5 years. Engineers are testing a full-scale prototype, entirely controlled by computers. The technology could equip cruise ships as early as 2025 and reduce carbon emissions by 50%.
The same desire to green maritime transport for Airseas and its kite-towed cargo project. The fifth largest shipowner in the world has already ordered 48 sails from the French company, leader in the sector. “Fuel oil represents the major part of our expenses. This system will allow us to save money and reduce our CO2 emissions”, explains Joichi Sasaki, marine engineer at K Line. Maritime transport represents 13% of carbon emissions worldwide. Wind propulsion appears to be the solution for the future to curb this phenomenon.
