Outline of Final Research Achievements |
This study conducted a comparison of the policies used to promote the production, diffusion and use of hydrogen in three countries (Japan, United States (California) and Germany) as well as barriers impeding market growth. The study covered the use of renewable hydrogen in transport and the production and diffusion of fuel-cell passenger vehicles. It adopted a mixed methods approach, combining data from interviews and document analysis. The study produced three detailed case studies on the hydrogen market for each country from the perspective of vehicle production, utilization/demand, infrastructure and hydrogen production, and cross-cutting institutional issues. The study found that all market growth in all three countries is slower than expectations due to high costs and a small number of actors in the market. Production of renewable hydrogen in each country is limited and suffering from high costs due to low economies of scale.

Academic Significance and Societal Importance of the Research Achievements |
本研究では、公共政策、トランジション研究、交通学、経済学などの分野からの理論を統合的に活用し、独自性の高い形で比較分析を行った。再生可能エネルギー由来の水素の製造および燃料電池自動車の普及拡大を妨げる要因を明らかにし、共通の課題を抽出できた。その結果、日本、ドイツ、カリフォルニア州における市場拡大を推進するに当たって必要とされる打開策を提言し、学術論文投稿、学会発表、業界と一般向けの講演会、公共政策の提言など行なうにより、幅広く社会へ研究成果の発信と活用を行った。なお、学術への貢献としては、次世代自動車技術の社会技術的システムの発展とそれを阻害する諸要因を解明するための分析的枠組を展開できた。
