7-1-4 ライフサイクルエクセルギー分析に向けた産業連関表利用の提案

抄録

New technologies promoted the reduction of energy consumption, and the energy efficiency of society as a whole has been proceeding. However, effective use of low-quality energy might further reduce the energy consumption of society as a whole. In particular, next-generation energy systems such as renewable and hydrogen energy might be effective technologies for energy storage and transportation. However, simple indicators of energy consumption could not take into account the quality of energy. Exergy is an indicator that could consider the quality of energy. The results of the assessment for the exergy-based technology could create the value of new energy technologies. This study aims at proposing a method for analyzing exergy consumption over the life cycle by applying input-output tables. In this presentation, I would report on the methodology under construction and case studies using it.
