LONDON, Aug 21 (Reuters) – A Cargill chartered dry bulk ship has launched on its first voyage since being fitted with special sails, aiming to study how harnessing wind power can cut emissions and energy usage in the shipping sector, the U.S. commodities group said on Monday.

The maritime industry – which accounts for nearly 3% of global CO2 emissions and is under pressure from investors and environmental groups to accelerate decarbonisation – is exploring a number of different technologies including ammonia and methanol in an effort to move away from dirtier bunker fuel.
