BMW CleanEnergy vehicles have both a hydrogen and a petrol tank. If one of the tanks is empty, the bivalent BMW engine unit switches over automatically to the other fuel system. One decisive advantage of the combustion engine is bivalence. It enables both hydrogen and petrol to be used, thus creating the ideal conditions for a transition from non-regenerative to regenerative drive energies. During electrolysis water is split into its components of hydrogen and oxygen. The hydrogen is stored and the oxygen is needed in the vehicle for the
last quarter of the century".
France was the largest stakeholder in the L3S programme; French aerospace manufacturer Aérospatiale served as the prime contractor and held responsibility for performing the integration of all sections of the vehicle, while French engine manufacturer Société Européenne de Propulsion (SEP) provided both the first and second stage engines (the third stage engines were produced by Air Liquide and German aerospace manufacturer MBB). Other major companies involved included the French electronics firm Matra, Swedish manufacturer Volvo, and German aircraft producer Dornier Flugzeugwerke. The
