Japanese giant NYK has unveiled a design for an emissions-free ship as part of its drive towards IMO's 2050 climate targets.

The 200-metre NYK Super Eco Ship 2050 has been devised with MTI and Finland's Elomatic to update its previous NYK Super Eco Ship 2030, created in 2009.

The new version makes use of advances in technology relating to green and digitalisation initiatives.

The pure car and truck carrier (PCTC) will see a 70% reduction in the power needed to operate it.

The hull has been remade to decrease water friction, reducing its weight, and fuel cells will power electric propulsion.

Solar energy and hydrogen produced from renewable energy sources will also be used, cutting all CO2 emissions.

Propulsion efficiency is increased by replacing conventional propellers with flapping foils that mimic the movements of dolphins.

Waste heat recovered from the fuel cells is also used.

An air-lubrication system will reduce the frictional resistance between the vessel’s bottom and the seawater by means of bubbles sent to the hull.

IMO’s target is for shipping to cut its CO2 emissions by 50% by 2050
