A research team at Chalmers University of Technology has demonstrated a unique method that reduces the aerodynamic resistance of ships by 7.5 per cent. This could pave the way for large cargo ships to be propelled by wind alone, as wind-powered ships are more affected by aerodynamic drag than fossil-fueled ones. To meet international climate targets, the carbon emissions from shipping must be reduced by more than 50 per cent by 2050 compared to 2008 levels. As much as 99 per cent of global shipping is currently dependent on fossil fuels. The researchers’ method could open up new possibilities for wind-powered propulsion. In the next few years, will probably see ships combining wind and fuel-powered propulsion.
