Demonstration
of buses fuelled
with natural gas and hydrogen
in Dunkirk and Toulouse
A first step towards the hydrogen economy
The principal tasks of Althytude are as follows:
- to install a system of production of hydrogen as well as a distribution of the blend of natural gas (present on each site) and of produced hydrogen;
- to adapt the buses to the new fuel;
to follow in the field their performances as well as the operation of the equipment from the production of hydrogen to the use in the buses.
As showed in various foreign experiments, the addition of hydrogen in natural gas increase technical (better output and increased flexibility) and environmental performances (less greenhouse gases and less local pollutants ). This mixture of natural gas and hydrogen constitutes moreover a realistic transition towards the hydrogen economy using existing technologies.
The parallel implementation of the two projects in Dunkirk and Toulouse will allow relevant comparisons, because the criteria and the methods evaluation, the means of measurement and the instrumentation, will be defined in a common way. A specific activity of evaluation is included in the project, in order to collect data from the two sites:
pathways considered (production of hydrogen, exploitation of the station of filling, use in the buses)
on the various energy
on the various evaluated aspects (environmental and energy performances, safety, public
The results will be thus synthesized and
used for the needs for transverse studies (Analysis of the Cycle of Life, potential of the energy dies).Althytude
