2. Motivation of the ENUBA project
- Elektromobilität bei schweren Nutzfahrzeugen zur Umweltenlastung von Ballungsräumen1
Road-freight emissions are a major challenge
Freight traffic in Europe is expected to double upon 2050
Goal of the EU-Commission:
Reduce CO2-Emission to 80% of 1990 level by 2050
Logistics optimization and capacity investment of rail system cannot
significantly reduce heavy duty road transport
Heavy duty road transport is responsible for a third of overall transportationrelated CO2-emissions – technical solutions are still absent
An electric alternative is missing

7. eHighway – electrification of hybrid trucks via an
overhead catenary system
eHighway system description
Siemens eHighway
An approach to electrified heavy duty road transport,
which reduces emissions, is economically feasible and
efficient
Optimized efficiency due to direct energy
transmission
Energy recuperation and exchange between
decelerating and accelerating trucks, excess brake
energy feed-in into power grid possible
Safety of catenary system operation has been proven
in various road traffic applications (e.g. trolley buses,
tramways)
Experiences from rail and tramway underline
extensive life-cycles and low operation and
maintenance costs
Swift integration into existing traffic infrastructure and
no concessions on operation of alternative vehicles

10. Challenges for port cities
• Ports serve as an economic driver for the city and the region. In the past
freight volumes have grown faster than GDP.
• A key challenge in realizing the benefits of trade is to overcome the
environmental impacts from transport. For many ports this environmental
challenge is primarily about improving air quality.
Source: Herman Journée & Patrick Verhoeven: ESPO / EcoPorts Environmental Review (2009)
• Much of air pollution comes from the road freight in and out of port area
Road-freight emissions are a challenge for port cities
