CNSS General Assembly, Newcastle, 9 June 2011

Emissions and Modeling

Volker Matthias and WP5 members


Tasks

•Monitoring and simulation of pollutant generation and spread – create an updated emission inventory

•Translate emissions into concentrations by numerical modeling

• Show case: modeling and simulation of air quality in a harbour region

• Development of an implementation strategy for clean shipping technology

from ships

NOx in summer


Available inventories:

more recent: DCMR year 2008

Based on AIS data

Number and type of ships in 13 ship and 8 size classes

Observations in 6 min intervals

Individual ship characteristics from a ship data base

Grid resolution: 0.5 x 0.5 km2, 5 x 5 km2

Emission factors from literature (TNO)


Emission map (DCMR inventory)

NOx in January


Revision of emission factors

Dependence on • engine type• speed • type of operations• fuel type• abatement technologies

Very important in harbour regions (manoeuvring)

Calculation of variable emission factors: U Newcastle


Measurements aboard ships (GL)

Three ship types:Cruise ship, container ship, feeder

Species:NOx, CO, CO2, SO2, Hydrocarbons

Different operation modes: Manoeuvring, slow speed, normal speed

Different engines and fuels:Main and aux. engines, marine diesel and heavy fuel oil


Concentration maps – sea going ships

Results for 2000 by HZG


NOx share in the Rijnmond area

byDCMR


Show cases

Application of model systems from HZG and DCMR in 2-4 regions

First priority:Rotterdam, Hamburg

Second priority:Bergen, Gothenburg

Comparison to observations of concentrations necessary


Emission Scenarios

What-if-questions

Reduction of emissions and concentrations due to the implementation of:

• Onshore power supply • Use of LNG • SECA (0.1 %S)• NECA• Abatement technologies (e.g. SCR)• Changes in ship operations (e.g. slow steaming)• …


Implementation

Which measures will give the highest benefit in air quality improvements?

Which measures have a good cost/benefit ratio?

Which measures have a good chance to be implemented?

What can be done to support the implementation of efficient ways to reduce air pollution?


Summary

Detailed ship emission inventories are available for the North Sea and the Rijnmond area

A new inventory will be built up to cover other regions

Emission factors will be updated and checked by on-board observations

Show case regions are defined, air quality observations are collected

Scenarios are defined in cooperation with WP3 and WP4
