Hydrogen, energy vector for the future? Or, on the contrary, limited to its current applications in the field of chemistry and refining for decades to come, possibly even until the end of the century? There is much controversy over this issue and two sides to the argument. Advocates of the hydrogen civilization consider that, following a technological revolution hydrogen will play a universal role alongside electricity as a substitute for fossil fuels, especially (but not only) in transport, leading to radical elimination of CO2 emissions. For the skeptics, and even outspoken opponents, hydrogen will remain restricted to its current applications due to the insoluble problems inherent to its generalized use, especially in transport. This book highlights the increasing and inevitable role of "energy" hydrogen – as opposed to chemical hydrogen – in the key sectors of transport and "clean" electricity production.

Changes in the world energy context, the increasing awareness of the environmental stakes and the development of research on the production of second and third generation biofuels revealed a clear need to write a new book which updates and complements all technical, financial and environmental aspects of Les Biocarburants – État des lieux, perspectives et enjeux du développement (Biofuels – Current status, outlook and development stakes) published in 2006. This new book provides a detailed state of the art of the first generation biofuel production technologies. It describes the new «second generation» pathways which use lignocellulosic biomass as raw material is starting to find industrial applications, thereby reducing the competition between the food resource and the use of agricultural materials for energy purposes. It also provides a technical update on the algaeto-energy pathway (third generation), and the production of methane and hydrogen by biochemical pathways.
