Developments in hydrogen vehicles

Hydrogen is a potential secondary energy carrier that meets the requirements for an energy source of the future. Its combustion does not produce carbon monoxide, carbon dioxide or hydrocarbons. Years of basic research at Daimler-Benz into the storage of hydrogen in metal hydrides and the hydrogen operation of reciprocating piston engines, and the results obtained with a number of experimental vehicles formed the basis for a fleet test of ten vehicles under everyday conditions which has been underway in Berlin since October 1984.
