Study of Demand for CO₂-free Hydrogen in Japan and the World

Abstract

世界及び日本における CO 2 フリー水素の導入量の検討 石本祐樹，黒沢厚志，笹倉正晴，坂田 興Evaluation of global hydrogen demand in electricity, stationary and transportation sectors has been conducted under the assumption that CO 2-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 CO 2 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 CO 2 capture and storage in the power sector.

A New Zealand Perspective on Hydrogen as an Export Commodity: Timing of Market Development and an Energy Assessment of Hydrogen Carriers

“…The prospective demand for hydrogen was recently explored [21] to establish a trading link between Patagonia and Japan (Figure 2). While the 2017 Ishimoto reference does not seem to contain the reported data, an earlier paper by the same author [22] indicated that initial demand would be due to stationary fuel cells for combined heat and power (CHP), with transport becoming significant after 2030 and power generation from about 2045.…”
