The world economy is dependent on imports and exports. Large shipping fleets are essential for transporting a huge number of products, but cargo ships have their drawbacks. They contribute to 3% CO2 emissions, 9% SOx emissions, and 18%–30% NOx emissions, which is not ideal! To reduce the carbon emissions caused by the fossil fuel engines, a wind propulsion solution is the right option. This helps in minimising the fuel usage, further bringing down the overall carbon emissions.

The two types of solutions in this category are as follows:

Rotor sail

  • Cylinders are placed vertically on the deck and spun using an electric motor to propel the ship.
  • This works by redirecting the airflow of the wind as air on one side is accelerated and dragged around the cylinder while it is slowed on the other side, creating a vortex.
  • This reduction of airflow creates a pressure difference helping propel the ship forward.

Vertical Axis Wind Turbine

  • NACA proficiency-based straight blade
  • Rotates based on the lift force produced by the NACA propeller. When the wind blows, a pocket of low-pressure air forms on one side of the blade.
  • The low-pressure pocket then pulls the blades towards it, causing the rotor to run.
  • To be placed on the ship’s stern.
  • Omni-directional works effectively with the wind blowing in any direction.
