摘要

Hydrogen(H_2)receives much attention to mitigate climate change and strengthen energy security. This study analyzed the economic viability of H_2 energy with a focus on the electricity and transport sectors, employing a spatially-disaggregated global energy system model. The simulated period is from 2015 to 2050. The results suggest that, in addition to strict CO_2 regulation policies, significant cost reductions of H_2 production technologies would be prerequisite to accelerate H_2-fueled power generation globally. By contrast, deployment of fuel-cell vehicle appears more sensitive to vehicle price, rather than the H_2 supply costs. Among H_2 production processes, gasification of coal and reformation of natural gas, combined with carbon capture and storage, are estimated to be cost-efficient, implying opportunities for H_2 trade between coal and gas resource countries and energy consumers. Yet, again, improved economics are necessary for maritime H_2 transportation, including liquefied H_2; otherwise, H_2 trade would be limited to pipeline. If maritime H_2 trade becomes economically viable, natural gas and coal in Australia could be competitive feedstock for Japan. Long-term policies to support research and development are crucial to commercialize H_2 supply system.
