HHI develops high pressure SCR system to reduce NOx emission

South Korea's Hyundai Heavy Industries (HHI) has unveiled a new high pressure selective catalytic reduction (HP SCR) system, designed to reduce nitrogen oxide (NOx) emission from two-stroke marine engines.

Claimed to be the world's first such product, the system is said to comply with IMO NOx Tier III requirement, which came into force last month.

The system is believed to be capable of reducing NOx emissions by up to 99% by means of using ammonia as a catalyst.

The HP SCR is said to be a result of 18 months of research and development.

HHI has completed the certificate test of HP SCR in December and has been approved by DNV-GL.

The environment-friendly marine engine is expected to reduce cost incurred on fuel since it can run on heavy fuel oil which costs half as much as marine gas oil.

"The system is believed to be capable of reducing NOx emissions by up to 99% by means of using ammonia as a catalyst."

The new product is deemed as HHI's effort to develop new technologies to cater to the marine market's demand for 'eco-friendly, more efficient and smarter ships.'

The first set of the equipment will be incorporated in a 20,600m³ LPG carrier which is being constructed at Hyundai Mipo Dockyard, a shipbuilding affiliate of HHI.

The company has managed a delivery order of five HP SCR systems and has set an annual order target of more than 100 units by 2018.

Last month HHI announced plans to build a floating storage regasification unit (FSRU) to Russian Maritime Register of Shipping (RS) class.
