Mitsui O.S.K. Pursues Revolutionary Zero-Emissions Cargo Ship

In an ambitious effort to revolutionize maritime transportation, Mitsui O.S.K. Lines (MOL) is working on developing a zero-emissions sailing vessel that relies on wind and hydrogen power to transport cargo around the world.

This innovative approach seeks to reduce greenhouse gas emissions in the shipping industry while exploring a new frontier in sustainable technology.

The proposed “Wind hunter” vessel operates on a two-fold principle.

When strong winds blow, the sails capture the wind, propelling the ship forward. Simultaneously, an underwater turbine rotates, generating electricity and producing hydrogen.

The hydrogen is then stored in tanks in the form of Methylcyclohexane (MCH).

During periods of lighter wind, the stored hydrogen is used as fuel in a fuel cell system, providing electricity to power electric propellers that propel the ship forward.

Preliminary yacht verification tests have been successfully conducted in Omura Bay, Nagasaki Prefecture.

MOL has announced plans to begin constructing hydrogen production vessels, featuring multiple sails and measuring 60 to 70 meters in length, starting in 2024.

These “Wind hunters” will seek out strong wind areas, optimizing their routes to maximize energy efficiency.

With a goal of developing a large zero-emissions cargo ship by 2030, Mitsui O.S.K. is poised to make a significant impact on the shipping industry’s environmental footprint.

If successful, the Wind hunter project has the potential to completely redefine the concept of maritime transportation, making it a key player in the global push for sustainability and ESG initiatives.
