Vale on the Way to Decarbonization
Vale is ensuring its efforts in supporting the maritime sector to accomplish the decarbonization ambition of the International Maritime Organization (IMO). The company also favours the Paris Agreement; scope 3 emissions are benchmarked for a reduction of 15% by 2035 and cover shipping. Vale’s Ecoshipping program, launched in 2018, stimulates partnerships in R&D with shipowners to promote technologies aimed at decreasing greenhouse gas (GHG) emissions and enhancing the performance of their fleet. Projects cover second-generation Valemaxes, Guaibamaxes, multi-fuel tanks on ore carriers, and the rotor sails initiative.
Anemoi’s Rotor Sail Technology
As one of the leaders in rotor sails, Anemoi offers technological assistance that helps a ship or fleet decrease its fuel expenditure and lower emissions on CO2, SOx, and NOx. The rotor sail uses the pressure difference generated around a rotating cylindrical sail installed on the deck to provide a ship with auxiliary propulsion. Installation on the NSU TUBARAO is expected to reduce fuel consumption and CO2 emissions by 6-12%.
NSU’s Efforts in Sustainability
NSU undertakes proactive initiatives to enhance the efficiency of its vessels and to reduce GHG emissions. This includes embracing energy-saving devices such as rotor sails. It assesses and explores next-generation fuel-powered ships for their integrated sustainable shipping mission.
