gen production concentrated in larger centres and its distribution by pipelines is
more effective than local production 105 .
Progress in hydrogen filling network development in the EU till 2009 is
shown in Fig. 16. As can be seen, the leaders are Germany, Italy, France, the
Benelux and the Nordic countries.

Another “green” alternative to fuel burning cars are hybrid propulsion cars,
most often electric-fuel, but also hydrogen-fuel and electric-hydrogen-fuel. Fuel
engines and electric motors can work alternately or side by side, as the need
may be, e.g., electric motor in urban traffic and fuel engine in long distance traffic.
The electric motor can be a generator, charging the batteries or the capacitor
when powered by the fuel engine or as a result of engine braking. While in urban
traffic the future belongs to Battery Electric Vehicles or FCVs, in long distance
traffic hybrid cars are likely to be more useful, owing to their greater
