The paper surveys the literature on the competitiveness of alternative hydrogen pathways in the transport sector. The competitiveness of the alternative systems can be differentiated in the ?well-to-tank (WtT)? and ?tank-to-wheel (TtW)? sections of the pathway transforming primary energy to transport services and in market competitiveness and societal competitiveness. The major societal competitive advantage of hydrogen is its convertibility to electricity and from any other source of energy. This enables a flexible use of natural gas and primary electricity as transport fuels. The major advantage in market competitiveness is the energy efficiency of the fuel cell. This advantage is, however, to some extent balanced by the costs associated with conversion, transport, and storage. The balance between these factors required for market competitiveness is identified
