With the recent development in marine regulations, the need to stay competitive in the Norwegian marine sector, and to share our part of the responsibility for environmental emissions by meeting our international obligations, increased the research efforts will be required.
Efficient, complete combustion of natural gas involves temperatures that lead to NOx formation. It is generally difficult to maintain high efficiency, lower formation of NOx and avoid methane slip under the dynamic loads of an engine. A combination of methane oxidation and selective catalytic reduction of NOx is therefore required.
The project targets new knowledge and innovation for emissions abatement, more specifically nitrogen oxides (NOx) and methane (CH4), in the marine sector.
A concept is envisaged with a dedicated catalytic unit for removing CH4 and non-methane hydrocarbons (NMHC) and thereby also lowering the oxygen concentration, which will be followed by a selective catalytic reduction unit for NOx removal. It is also a goal to replace noble metals in current state of the art systems by more available less expensive elements.
