Marine SCR Systems
NOx Reduction by SCR Catalyst on Ships; Ships's engines produce harmful nitrogen oxides, these emissions from the maritime traffic have serious consequences for the human health. that is why strict legal limits apply. The IMO (International Maritime Organisation) reduces the limits for NOx / Nitrogen Oxides step by step. The limits apply in the so called ECA zones (Emission Control Area), there are already plans to extend the areas. In the norwegian waters a tax applies for the emissions of NOx. The Nox-Fondet (www.nho.no) raise a tax and aubsidises the installation and operation of measures to reduce ship's emissions.
Existing Emission Control Areas include:
- Baltic Sea (SOx, adopted: 1997 / entered into force: 2005)
- North Sea (SOx, 2005/2006)
- North American ECA, including most of US and Canadian coast (NOx & SOx, 2010/2012).
- US Caribbean ECA, including Puerto Rico and the US Virgin Islands (NOx & SOx, 2011/2014).
