| 研究実績の概要 |
Research during this year concerned the question: “What risks emerge to national decarbonisation goals from relying on the use of blue and green hydrogen?” To answer this question, we conducted an integrative literature review to develop a framework for assessing the decarbonisation risks of different hydrogen and ammonia production pathways and end uses. We conceptualised risks using the IPCC’s feasibility categories for climate change mitigation options (IPCC, 2022), that considers the geophysical, environmental-ecological, technological, economic, sociocultural, institutional, and geopolitical groundings of risks to achieving decarbonisation through hydrogen development.

| 今後の研究の推進方策 |
This year, we will use the previously developed framework to consider the strategic risks to national decarbonisation goals emerging from national hydrogen strategies in four nation-states proposing different configurations of international hydrogen economies. Specifically, we consider two states that plan to be net importers of hydrogen produced overseas and shipped to their ports (Japan and Germany), and two that plan to be net exporters meeting the global demand represented by the former (Australia and the United States). Using document analysis, we review the hydrogen strategies of each country to identify decarbonisation risks that might threaten the viability or long-term stability of emissions reductions.
