サブサハラ・アフリカの再エネ投資ギャップを、PRISMA準拠の系統的レビュー（43研究）で分析。公的・譲許的資本が主要手段だが、競争的で自立した市場形成や民間投資の持続的動員には至っていない。資本コスト高、為替・オフテイカーリスク、政策の一貫性欠如、公益事業の信用力不足が銀行可能性を制約。資金手段は必要だが十分ではなく、制度の信頼性と国内金融市場の発展が鍵と結論づける。
English
A PRISMA-guided systematic review of 43 studies on renewable energy financing in Sub-Saharan Africa. Public and concessional capital dominate, but state- and donor-led models fail to build self-sustaining markets or durable private investment. High capital costs, currency and off-taker risk, policy inconsistency and weak utility creditworthiness constrain bankability; instruments are necessary but insufficient without institutional credibility and financial-market reform.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX文脈では直接の接点は薄いが、官民・譲許的資本の役割と銀行可能性の制約要因は、日本のトランジション・ファイナンスやアジア新興国支援の設計に示唆を与える。
In the global GX context
Speaks directly to global transition-finance debates: it shows why blended and concessional capital alone cannot close the investment gap without institutional credibility and domestic financial-market depth—relevant to MDB reform and just-transition finance discussions.
👥 読者別の含意
🔬研究者:Provides a structured synthesis of financing instruments and institutional constraints, useful as a baseline for empirical work on bankability in frontier markets.
🏢実務担当者:Highlights off-taker, currency and policy risks that determine project bankability when structuring renewable investments in SSA.
🏛政策担当者:Underscores that concessional finance must be paired with policy coherence, utility reform and domestic financial-market development.
📄 Abstract（原文）
<title>Abstract</title> <p>Sub-Saharan Africa possesses substantial renewable energy resources yet attracts a disproportionately small share of global clean-energy investment, leaving persistent financing gaps that constrain energy access and transition objectives. This systematic review examines financing instruments, renewable energy market models, investment outcomes and institutional conditions across Sub-Saharan Africa. A PRISMA-guided search identified 198 records; after removal of 88 outdated or duplicate records, 110 were screened, 66 excluded, 44 full texts assessed and one further document excluded, leaving 43 studies for synthesis. Evidence was extracted using a structured review matrix and synthesized through thematic analysis supported by NVivo, alongside descriptive examination of financing instruments and technologies. Public and concessional capital including government grants, concessional loans and development-partner finance emerged as the most prominent financing mechanisms. State-led and donor-supported models enabled project initiation but did not consistently create competitive, self-sustaining markets or mobilize durable private investment. High cost of capital, currency exposure, off-taker risk, policy inconsistency, weak utility creditworthiness and limited institutional capacity constrained bankability. Decentralized systems, particularly mini-grids and off-grid solar, were important for access but faced tailored financing and regulatory barriers. The review concludes that financing instruments are necessary but insufficient: investment effectiveness depends on institutional credibility, coherent policy implementation, domestic financial-market development and system-level reform.</p>
