This book edited by members of the Committee of Future Energy and Social Systems The Society
of Chemical Engineers Japan describes energy technology roadmaps for Japan post-Fukushima. In
this work energy technology experts show quantitatively the advantages and disadvantages of
major energy technologies with which they are involved in a unified chapter structure with
figures illustrating the technology development perspectives. The future energy vision for
Japan together with the pathway is quantitatively discussed explicitly considering the
contributions of individual energy technology by referring to the technology roadmaps. The
pathways for future energy vision thus derived will be useful not only for all energy
researchers but also for graduate students in the field to grasp the potential of the
technologies and future energy system of Japan.
