Airbus (Toulouse, France) is equipping one of the vessels it uses to transport aircraft subassemblies, chartered from shipowner Louis Dreyfus Armateurs (Suresne Cedex, France), with a wind-assisted propulsion technology that captures wind energy to generate thrust, delivering savings in fuel consumption and CO2 emissions.
The eSail, developed by the Spain-based firm bound4blue (Barcelona, Spain), is said to create as much as six to seven times more lift than a conventional rigid sail. It consists of a sail-like vertical surface and an electric-powered air suction system that helps the airflow to re-adhere to the sail, generating additional lift and thereby reducing the load on the ship’s main engines. Bound4blue reports that its eSails are currently built in part from composite materials, specifically the superior winglet.
Three 22-meter-high eSails will be fitted to the Ville de Bordeaux ahead of a 6-month performance monitoring period starting early 2024. The Ro-Ro ship regularly ferries A320 Family subassemblies from Europe to Mobile, Ala., U.S. for final assembly.
“We at Airbus have been studying wind-assisted technologies as a potential energy source for our maritime operations for many years,” Nicolas Chrétien, head of sustainability and environment at Airbus, says. “As we embark on an exciting journey with our partners Louis Dreyfus Armateurs and bound4blue, we reaffirm our ambition to explore all innovation pathways to develop more sustainable maritime solutions and further reduce the carbon footprint of our industrial operations. This technology looks promising and we are eager to start testing it in real conditions by the end of the year.”
