CCEM NADIP

Duration: 2010-2013

Contact: Sebnem Aksoyoglu, sebnem.aksoyoglu@psi.ch

Scope of project

This is a CCEM-CH Project where 5 laboratories from EMPA, PSI and ETHZ join their competences to improve the NOx abatement in diesels by improving the efficiency of urea selective catalytic reduction (SRC) DeNOx systems for mobile heavy-duty diesel and naval engines by optimization of the urea decomposition upstream the SRC catalyst. Our task as the modelling group at PSI was to simulate the impact of emissions from naval engines on the atmosphere and air quality.

Key findings

In this project, we investigated the effects of ship emissions on pollutant concentration and deposition in Europe (Aksoyoglu et al., 2016). Spatial and seasonal variation was studied as well. The air quality model CAMx was run with and without ship emissions in order to determine the effects of these emissions on the air quality in 2006. The results suggest that ship emissions cause an increase mainly in concentrations of inorganic aerosols. The largest effects were predicted around the Mediterranean Sea. Impacts of ship emissions on ozone and PM2.5 (particulate matter with a diameter smaller than 2.5 micrometer) are shown below.

Funding

This project is funded by CCEM (Competence Center Energy and Mobility).
