Prospects of Modern Wood Gas Cogeneration Renewable Energy Supply in Japan − Case Study of ICU

Authors: Eckhard Hitzer, Mark Langager, Nobyuki Miyazaki, Takashi Kibe

In this article we introduce scalable modern commercial wood gas cogeneration technology of micro scale, beginning at 35-45 kW electric power, scalable up to 800kW electric power, as offered by several international companies. Cogeneration means to use both electricity and heat, which leads to an overall efficiency of converting the chemical energy in wood of up to 90%. We discuss aspects of technology, sustainability, forest ecology, local and international fuel quality standards, long term cost efficiency, potential for attracting various forms of official financial support and potential risks involved. In particular we make the general study concrete in the form of a case study on renewable energy supply for the International Christian University campus in Mitaka, western Tokyo. Changing scale parameters in order to adapt to the local energy demand, we expect that this case study can be transferred to other schools, universities, institutions, businesses and buildings in Japan. We further try to address the question as to what contribution this technology can make to the future national renewable energy supply in Japan.
