Analyzing the necessity of hydrogen imports for net-zero emission scenarios in Japan

With Japan’s current plans to reach a fully decarbonized society by 2050 and establish hydrogen society, substantial changes its energy system need be made. Due the limited land availability in Japan, significant amounts of are planned imported both targets. In this paper, novel stochastic version open-source multi-sectoral Global Energy System Model conjunction with power dispatch model is used analyze impacts price imports on transformation Japanese considering net-zero emission target. This analysis highlights that poses valuable resource specific sectors system. Therefore, importing can indeed positively impact developments, although up 19mt will case cheapest available hydrogen. contrast, without any imports, demand nearly doubles compared 2019 due extensive electrification non-electricity sectors. However, not necessarily required emissions. all cases, however, large-scale investments into renewable sources • Hydrogen certain non-power For generation, only plays minor role as peak-load technology. Without 2019. Importing Extensive made cases.
