The impact that hydrogen and fuel cell technology can have on the security of European transport fuel supply is addressed in this paper. This impact depends primarily on the primary energy commodities that serve as feedstock in the production of hydrogen. Natural gas as feedstock does not provide any improvement of security of supply. Coal with carbon capturing and sequestration provides in some respects a more secure supply of energy as will nuclear power. Renewable electricity and biomass based hydrogen does, however, offer a more secure supply in the sense that they are domestic and renewable.
