Reducing NOx shipping emissions  

With over 9000 large ships traveling the world, the air pollution caused by them is a major global concern. Air pollution from ships contributes to the overall air quality problems encountered by people worldwide and also affects the natural environment.  
One of the main pollutants from the ship’s emission are Nitrogen Oxides (NOx). NOx is a byproduct, created by combustion of heavy fuel oil in the engine. The exhaust gases are emitted into the environment in the form of smoke.  

To curb air pollution from ships, the International Maritime Organization (IMO) has mandated that shipping emissions be reduced by 50% by 2050. 

Clean air is our business

Today only a minority of new marine engines are equipped with air pollution control systems but this picture will soon change dramatically. As of 2021 many more new engines will be equipped with Selective Catalytic Reduction (SCR) systems to reduce NOx emissions.  
Clean air is at the core of Umicore’s vision. We are one of the world’s leading producers of catalysts for stationary use (industrial plants and ships). Umicore has supplied SCR systems and catalysts for marine engines since 1988.  
Today, Umicore produces the lightest and most efficient catalysts with premium technology. The Umicore Marine SCR DNX® catalysts are optimized to eliminate NOx from engines of all sizes. The unique catalytic products are vibration resistant and can endure changing temperatures. They are low weight, fit the limited space in ships and perform extremely well within regulations. 
It is anticipated that regulations will be further tightened with stricter emission norms. Revisions to the regulations will have a significant beneficial impact on the atmospheric environment and on human health. In this context, Umicore’s DNX®-Marine catalysts offer a unique solution to move to a greener and sustainable ocean economy.
