Eds. Michael Ball, Martin Wietschel.In the light of ever-increasing global energy use, rising costs of energy services, concerns over energy supply security, climate change and local air pollution, this book centres around the question of how growing energy demand for transport can be met in the long term. Responding to sustained interest in and controversial discussion of the prospects of hydrogen, this book highlights the opportunities and the challenges of introducing hydrogen as alternative fuel in the transport sector from an economic, technical and environmental point of view, and with a global geographic scope. Through its multi-disciplinary approach the book provides a broad range of researchers, decision makers and policy makers with a solid and wide-ranging knowledge base concerning the hydrogen economy. Particular highlights include: assessment of the benefits and downsides of hydrogen compared to other alternative fuels strategies and scenarios for a hydrogen infrastructure build-up interactions between hydrogen production and the electricity sector long-term global hydrogen supply scenarios and their impact on resource availability the potential of hydrogen for decarbonising the transport sector macro-economic impacts of introducing hydrogen
