Project Description and Objectives: |
The investigation is subdevided into the four parts:
Description of technologies (electricity production, hydrogen production as well as H2-conditioning, -storage and transportation)
· Evaluation of the technical and economic feasibility
· Scenarios for the future production of hydrogen
· Consequences for the utilisation of hydrogen as energy carrier in transportation.
In the first part Description of technologies the technical principles as well as the present technical and economic development of electricity production technologies (fuel mix in Germany and renewable technologies), hydrogen production technologies (fossil and renewable) and H2-conditioning, -storage and transportation technologies are described.
In the second part Evaluation of the feasibility the present technical and economic state of the art as well as the prospects for future developments are evaluated with regard to technical, economic and structural aspects.
In the third part Scenarios for the future production of hydrogen possible hydrogen introduction scenarios for Germany for the horizons 5 to 10 years and 10 years and after are elaborated. As a result, hydrogen sources will probably be tapped in Germany in the following temporal order:
· Hydrogen from fossil sources (by-product H2)
· Decentralised local production of hydrogen from biomass
· Importation of hydrogen from large remote renewable power stations
· Decentralised local production of hydrogen from wind energy and photovoltaics.
The transitions from one phase to another will be smooth.
In the fourth part Consequences for the utilisation of hydrogen as energy carrier in transportation boundary conditions for the acceptability of cost differences of a factor of two between fossil fuels and renewable hydrogen within roughly a decade and for the development of a market for energetically used hydrogen in transportation are listed:
· Reduction of local emissions.
· Reduction of the fuel consumption of automobiles by down-sizing and more efficient propulsion systems.
The global CO2-problem: CO2-neutral energy carriers have to be utilised; the means of transport have to become technically more efficient; the means of transport have to be used more efficiently.
Fossil energy carriers are finite.

Preliminary or Final Results: |
As a result, within a time frame of 5 to 10 years about 2 million and in the time frame after 10 years and after (starting in 2017) about 20 to 25 million passenger cars could be driven with hydrogen.
