本稿はインドの国家グリーン水素ミッション（2023年）を政策・技術経済分析し、グリーン水素の生産コスト（3.9～12.8 USD/kg H2）が化石燃料由来水素（1.6～6.4 USD/kg H2）よりも高いこと、また水不足問題（1kg H2あたり約9リットルの純水が必要）を指摘。国際的な実装ギャップを明らかにし、SIGHT制度や国内電解槽製造の重要性を結論づける。
English
This paper provides a policy and techno-economic analysis of India's National Green Hydrogen Mission (2023). It highlights high production costs (3.9–12.8 USD/kg H2) compared to fossil-fuel-based hydrogen, water scarcity issues (~9 liters of demineralized water per kg H2), and a global implementation gap. The study concludes that domestic electrolyser manufacturing and the SIGHT initiative are key to achieving cost parity and a just transition.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は水素基本戦略を掲げ、インドなどへの水素サプライチェーン構築を進める。本稿はインドのグリーン水素政策の実態と課題を明らかにしており、日本企業のインド水素事業参入や、水素輸入戦略を検討する上で示唆に富む。また、水不足の指摘は、日本の水素製造における水資源管理の重要性を再認識させる。
In the global GX context
This paper offers a detailed case study of India's green hydrogen policy, relevant for global hydrogen strategy discussions. It identifies a common 'implementation gap' between announced projects and operational reality, a key challenge for international hydrogen markets. The water scarcity analysis adds an important sustainability dimension often overlooked in hydrogen roadmaps.

📄 Abstract（原文）
As India targets energy independence by 2047 and net-zero emissions by 2070, green hydrogen has emerged as a critical pivot for decarbonising ‘hard-to-abate’ sectors like steel, refining and heavy transport. This article provides a policy and techno-economic analysis of India’s National Green Hydrogen Mission (2023) within the global energy landscape. While green hydrogen offers a carbon-neutral alternative to grey hydrogen, its economic viability remains constrained by high production costs (3.9–12.8 USD/kg H2) compared to fossil-fuel-based methods (1.6–6.4 USD/kg H2). The study identifies a significant global ‘implementation gap’, where only a few of the announced hydrogen projects have reached the operational stage due to financing hurdles and supply chain constraints. Domestically, the research highlights critical sustainability challenges, specifically the requirement of approximately 9 litres of demineralised water per kilogram of H2, which may exacerbate water scarcity in India’s arid industrial hubs. The article concludes that while the Strategic Interventions for Green Hydrogen Transition (SIGHT) initiative and domestic electrolyser manufacturing are vital steps towards cost parity, India must balance its export ambitions with local resource preservation to ensure a truly just energy transition.
