During the last few decades, traffic has clearly increased faster than economic output. The traffic systems of many larger cities are threatening to collapse and in spite of an awareness of the limited oil reserves, a change in traffic volume cannot be anticipated.
The vision of sustainable mobility involves methods of moving people and goods internationally to a high standard but with less traffic. This would reduce the adverse impact on the climate and the national economy.


It requires the technologies and fuels used to also comply with the criteria of sustainability. In Germany, additional research, development and optimisation is taking place with regard to both of these approaches. Alternative propulsion technologies such as those for hybrid and electrical vehicles are already available and may replace the conventional diesel and petrol engines. Vehicles with fuel cells and combustion engines using hydrogen will make a considerable contribution towards protecting the environment and saving energy resources in future. Natural gas, bio-diesel, methanol, hydrogen or synthetic BTL (Biomass to Liquid) fuels might be used in tanks, instead of fuel made of mineral oil.
This website contains project descriptions regarding these topics, in particular alternative propulsion methods, concepts for the optimisation of components for zero-emission vehicles or potential applications for lubricants that can be broken down by biological means for rail-bound vehicles.

The employment of railed vehicles is connected to high capital investment for the overhead traction lines. Additionally, the degree of environmental friendliness depends on the primary energy used at power plants providing the energy needed. In the course of this project it is planned to investigate how new propulsion systems are able to fulfil the growing environmental demands regarding low emissions and resource protection but also if they present an economically advantageous alternative.
The innovative technology used for the inland container ship FUTURA CARRIER has been transferred to a tanker. The double-walled hull increases transport safety without restricting the volume of freight. In addition, fuel consumption and noxious emissions are reduced and impact on the waterways is low.

An analysis of energy and material flows showed that exploiting the energy content of the solvents can reduce the energy needed for the coating process and the waste generated in the paint shops. Expand…
The participating researchers developed designs of automotive castings that were optimized using bionic principles. The developed components have less mass and better mechanical properties than conventional components. Vehicular emissions, including CO2 emissions, and fuel consumption can consequently be reduced.

The first progress report on the German high-tech strategy was published in 2007. To ensure that the proposed aims in the field of aviation are achieved by 2020, simulation techniques are currently being developed in a Franco-German joint project. Support is also being given to the European technology initiative “Clean Sky”. More information is provided in the following German-language article.
The results of the study demonstrate that from a climate perspective, low sulphur fossil fuels and biofuels offer a viable alternative to heavy fuel oil with a high sulphur content used in large diesel engines. No technical adjustments to the engines are required for biofuels. However the cultivation of the biomass must be sustainable so as to achieve positive climate impacts. Expand…

Before now, there has been no satisfactory simulation technology that could accurately estimate the durability of exhaust system components subject to high levels of thermal and mechanical stress. Researchers at the Centre of Competence for Component Simulation in Freiburg, Germany, have recently found a solution. This means that it is now possible to strengthen potential weak points and prolong service life. Further information is available in the German-language article.
In the project a biological degradation stage was developed for light-density liquid separators. With the new biological procedure dispersed and emulsified hydrocarbons in motor vehicle waste water can be degraded.
Berlin has been given the opportunity to take an important step towards a forwards-looking, sustainable urban transport system with the support of the European Union. The Tellus Berlin project is being run by the Senate Department of Urban Development in close cooperation with FAV, the Berlin Transport Technology System Network. Most of the projects have been subdivided into three fields of activity: Intermodal Mobility, Freight-Logistics-Vehicles and Cross-Functional Tasks.
