日本語

ナイジェリア北部は年間6,271TWhのグリーン水素生産ポテンシャルを持ちながら、2025年時点で商用施設はゼロ。本研究は2015〜2025年の政策文書を4次元ガバナンス枠組みとSWOTで分析し、モロッコ・南アフリカ等5カ国と比較。太陽資源や電解技術ではなく、国家水素戦略・認証規則・ブレンドファイナンスの欠如が相互に強化し合う制度的空白が停滞の主因だと結論づける。

English

Nigeria's north holds an estimated 6,271 TWh/yr green hydrogen potential yet had no commissioned facilities by 2025. Using a four-dimension governance framework, thematic coding and SWOT across three national instruments (Energy Transition Plan, Climate Change Act, NDC3) benchmarked against Morocco, South Africa, Namibia, Egypt and Kenya, the study finds deployment is stalled not by solar resources or electrolysis technology but by missing institutional foundations: no national hydrogen strategy, no hydrogen-specific licensing/certification, and no finance architecture. Green ammonia in northern states is flagged as a near-term application.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本は2017年に世界初の国家水素戦略を策定し、水素基本法・認証制度・GX債による資金調達を整備してきた。本論文の「戦略・認証・金融の三位一体が欠けると資源があっても展開しない」という知見は、日本の水素政策の先行優位と、資源国への制度輸出・技術協力の余地を示す。

In the global GX context

As global hydrogen finance scales through mechanisms like the EU Hydrogen Bank and Japan's GX bonds, this paper argues that governance credibility is a precondition for concessional capital in resource-rich but institutionally constrained states. It adds a Global South perspective to transition-finance scholarship that is often dominated by OECD disclosure frameworks, and offers a comparative benchmark across five African hydrogen aspirants.

👥 読者別の含意

🔬研究者:資源賦存と制度能力の乖離という、低炭素転換研究における『ガバナンス前提条件』仮説の実証事例として参照できる。

🏢実務担当者:新興国での水素・アンモニア事業検討時、相手国の国家戦略・認証制度・ブレンドファイナンス整備状況を事前審査項目にすべき根拠となる。

🏛政策担当者:水素戦略の法的拘束力、水素専用の許認可・認証規則、公的資金と民間資金のブレンド設計の三点を政策パッケージとして整備する必要性を示す。

📄 Abstract（原文）

Nigeria’s northern zones receive some of the highest solar irradiance in West Africa, with an estimated annual green hydrogen production potential of 6,271 TWh. Yet, as of 2025, the country had commissioned no green hydrogen facilities. This study examines the policy and institutional factors behind this gap and considers its implications for Nigeria’s transition to a low-carbon energy system. It uses qualitative policy analysis of peer-reviewed research, international agency reports, and Nigerian federal policy instruments published between 2015 and 2025. A four-dimension governance framework, thematic coding, and SWOT analysis are applied to three national instruments: the Energy Transition Plan (Federal Republic of Nigeria, 2022), the Climate Change Act (Federal Republic of Nigeria, 2021), and the third Nationally Determined Contribution (Federal Republic of Nigeria, 2025). Evidence from Morocco, South Africa, Namibia, Egypt, and Kenya provides comparative benchmarks for identifying gaps in Nigeria’s governance framework. The findings suggest that stalled deployment reflects neither inadequate solar resources nor unproven electrolysis technology. Rather, key institutional foundations are missing: a dedicated national hydrogen strategy, hydrogen-specific licensing and certification rules, and financing arrangements capable of mobilizing private investment at the required scale. These gaps reinforce one another: concessional finance needed to close the cost gap depends on governance credibility that has yet to be established. Green ammonia production in the northern states emerges as a promising near-term application, with potential to ease land pressures associated with farmer–herder tensions. The study concludes with six policy recommendations, beginning with adoption of a binding national hydrogen strategy and creation of a blended-finance mechanism. It contributes to low-carbon transition research by showing that, in resource-rich but institutionally constrained states such as Nigeria, governance reform is a precondition for deployment.
