Abstract

In this study, we conducted a techno-economic analysis to estimate the deployment of zero-emission technologies (electricity and hydrogen) in Japanese transportation sector, considering the deep-decarbonization target by 2050. We used TIMES-Japan energy system analysis framework, which is following a whole-system approach. Results of calculations for energy demand of passenger and freight transportation by cars, buses, trucks, trains, airplanes, and ships are discussed after giving special attention to the capacities of low-emission technologies including renewables, nuclear, CCS, and hydrogen import in the supply side of energy system. Results of the calculations for the main scenario showed that zero-emission technologies would cover 75.6% of transportation energy demand in Japan by 2050, in order to achieve the 80% emission reduction target for the whole energy system.
