Abstract

Evaluation of global hydrogen demand in electricity, stationary and transportation sectors has been conducted under the assumption that CO2-free hydrogen is produced in seven regions by using a global and long-term intertemporal optimization model, GRAPE. CO2-free hydrogen was assumed to be transported to other regions. Applied CO2 constraint is 50% reduction for all regions and 80% reduction for developed regions in 2050 from the 1990 level. It has been found that under the severe CO2 constraint, approximately 800 Mtoe and 57 Mtoe of hydrogen is used in the world and in Japan in 2050, respectively. It has also been found that hydrogen demand in Japan is largely influenced by other zero emission technologies such as nuclear and CO2 capture and storage in the power sector.
