Abstract
In order to save energy and decrease environmental impacts in city thermal energy utilization systems, next generation energy utilizing technologies and their introducing contracture are proposed. The purpose of this paper is clarifying how to introduce the next generation technology such as off line chemical heat storage transportation system in the city. First, financial and political supports of next generation energy technology are discussed. It is showed that the supports are very few and next generation energy technologies are not carried out well. Secondly, in the case study of Chiba- and Kanagawa- Tokyo heat transportation system, the effectivity and merits of the off line chemical heat storage transportation are shown. As a result, more financial and political structure for introducing next generation energy utilization technology such as off line chemical heat storage transportation is found to be strongly needed for energy sustainable regional development.
