Abstract: The desire to maintain CO 2 concentrations in the global atmosphere implies the need to introduce ’new’ energy carriers for transport applications. Therefore, the operational consumption of each such potential medium in the ’natural’ exploitation of vehicles must be assessed. A useful assessment method may be the vehicle’s energy footprint resulting from the theory of cumulative fuel consumption, presented in the article. Using a (very modest) database of long-term use of hydrogen-powered cars, the usefulness of this method was demonstrated. Knowing the energy footprint of vehicles of a given brand and type and the statistical characteristics of the footprint elements, it is also possible to assess vehicle fleets in terms of energy demand. The database on the use of energy carriers, such as hydrogen, in the long-term operation of passenger vehicles is still relatively modest; however, as it has been shown, valuable data can be obtained to assess the energy demand of vehicles of a given brand and type. Access to a larger operational database will allow for wider use of the presented method.
