Hyundai Heavy Industries (HHI) has produced the world’s first High Pressure Selective Catalytic Reduction (HP SCR) system for the reduction of NOx emissions from 2-stroke marine engines.
The HP SCR can reduce NOx emission up to 99 per cent by using ammonia as a catalyst, and thus complies with IMO NOx Tier III requirements that took effect in January 2016. The eco-friendly marine engine can run on heavy fuel oil as opposed to the more expensive marine gas oil.
HHI completed the certificate test of the HP SCR in December 2015 in the presence of DNV-GL. The first HP SCR is to be installed in a 20,600 m3 LPG carrier under construction at Hyundai Mipo Dockyard, a shipbuilding affiliate of HHI. So far, five HP SCR systems have been ordered. The company expects this number to rise to more than 100 units by 2018.
