Wind Assisted Ship PropulsionTechnologies – Can they Help in Emissions Reduction?

According to International Maritime Organization, emissions coming from global shipping are expected increase 50% 250% by the year 2050. This concern led introduction of various regulations that aims encourage ship owners and builders explore innovative renewable technologies. The main focus this article is on wind-assisted propulsion technologies, as a complement propulsion, such rigid sail, soft wing kite, Flettner rotor. These technologies not widely accepted because have doubts due lack real-life results their implementation efficiency greatly depends design purpose. shows progress in field last 15 years which proved concept they potential reduce fuel consumption, thus emissions, double digits. conclusion drawn, savings percentages, rotor sails great future industry.
