南アフリカのバイオエネルギーは豊富なバイオマス資源と商業技術があるにもかかわらず、電力容量の0.5%未満に留まる。2000-2025年の文献を系統的にレビューし、政策・規制、原料・技術、展開成果の3側面から分析。断片的なガバナンス、投資インセンティブ不足、規制の不確実性が主な障壁であり、政策野心と実施のギャップが核心課題と結論。
English
Despite abundant biomass and commercial technologies, South Africa's bioenergy contributes less than 0.5% of electricity capacity. A systematic review of 116 studies (2000-2025) across policy, feedstock, and deployment dimensions identifies fragmented governance, weak incentives, and regulatory uncertainty as key barriers, concluding the main challenge is translating policy ambition into coordinated implementation.

日本のGX文脈において
日本の再生可能エネルギー政策、特にバイオマス発電のFIT導入後の課題と比較示唆に富む。日本でもバイオマス発電の導入が進む一方、持続可能性や地域統合の課題があり、政策と実装のギャップ分析は参考になる。
In the global GX context
This paper contributes to global understanding of policy-implementation gaps in renewable energy, relevant for countries with ambitious bioenergy targets but slow deployment. It offers a framework for assessing alignment between policy, technology, and outcomes that can inform international best practices and donor strategies.

📄 Abstract（原文）
South Africa possesses substantial bioenergy potential derived from agricultural residues, forestry by-products, municipal organic waste, wastewater sludge, and dedicated energy crops, positioning bioenergy as a potentially important contributor to the country’s low-carbon energy transition. Despite more than two decades of supportive policy, modern bioenergy remains a marginal contributor to the country’s energy system. Although previous studies have examined individual bioenergy technologies, feedstocks, environmental impacts, or policy frameworks, a comprehensive assessment of the alignment between policy ambition, technological readiness, implementation outcomes, and emerging sustainable development opportunities in South Africa remains lacking. This review presents a systematic integrative review of bioenergy development in South Africa, evaluating the alignment between policy ambition, technological readiness, and implementation outcomes. Literature published between 2000 and 2025 was systematically reviewed using Scopus, Web of Science, Google Scholar, and institutional publications. A PRISMA-informed screening process identified 427 records, of which 116 studies met the inclusion criteria for detailed synthesis. Evidence was synthesized across three interconnected dimensions: (i) policy and regulatory frameworks, (ii) feedstock availability and technological readiness, and (iii) deployment outcomes, implementation challenges, and future development opportunities. The findings reveal a persistent implementation gap despite abundant biomass resources and commercially established bioenergy conversion technologies Although global biofuel production exceeded 180 billion liters in 2023, South Africa’s installed bioenergy electricity capacity remains approximately 265 MW, representing less than 0.5% of the country’s approximately 60 GW installed electricity generation capacity. By comparison, installed solar and wind capacities exceed 8 GW and 3 GW, respectively. The review identifies fragmented governance, limited investment incentives, regulatory uncertainty, infrastructure constraints, and inadequate integration of bioenergy into national energy planning as the principal barriers to deployment. The review concludes that South Africa’s principal challenge is not biomass availability or technological capability, but translating policy ambition into coordinated implementation capable of scaling sustainable bioenergy deployment.
