This chapter examines the role of hydrogen, and fuel-cell vehicle technologies in particular, in contributing to a future sustainable transport system and also shows the limitation of such an approach. Particular areas that need to be addressed in this respect include emissions, safety, land use, noise and social inclusion. Vehicle technologies will play a key role in addressing several of these.
Introduction
Transport systems perform vital societal functions but in their present state cannot be considered ‘sustainable’. Particular concerns in this respect include climate change, local air emissions, noise, congestion and accidents. One of the most controversially discussed long-term solutions to today's problems of the transport sector is the introduction of hydrogen as an energy fuel and fuel-cell vehicles. In this chapter, we integrate the two debates – one on the transition to a ‘hydrogen economy’ and one on sustainable transport. We try to answer the question on what role hydrogen and fuel-cell vehicle technologies could play in a sustainable transport vision.
This chapter is structured as follows: Section 19.2 introduces the economic relevance of transportation by looking back at the beginning of industrialisation. Section 19.3 then summarises current evidence on the social effects of today's motor transport with reference to different world regions. Departing from this analysis, the subsequent section briefly derives a set of exit strategies towards a more sustainable transport future, considering a wide range of policy instruments and transport externalities.
