南部アフリカの都市部におけるハイブリッドエネルギーシステム（HES）の展開を2010〜2025年にわたり系統的にレビュー。PV・バッテリー（・系統）システムが主流で、平均電力コストは0.18ドル/kWh、CO2排出削減率は56.8〜90.3%と高い脱炭素効果を示す。都市部でのHES導入は経済性と環境性能の両面で有望だが、標準化された報告と政策的支援が必要。
English
A systematic review of hybrid energy systems (HES) in urban Southern Africa (2010-2025) finds PV-battery-grid dominance, with mean LCOE of $0.18/kWh and CO2 reductions of 56.8-90.3%. Urban HES shows strong decarbonization and economic viability, but requires standardized reporting and policy support.

📝 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、都市部のエネルギーシステムにおける再生可能エネルギー統合と脱炭素化の知見が、日本の都市部での分散型エネルギー導入やレジリエンス強化に示唆を与える。ただし、南アフリカ特有の系統不安定性を前提としており、日本の安定した系統への適用には注意が必要。
In the global GX context
This review provides empirical evidence on urban hybrid energy systems' techno-economic and environmental performance, relevant to global discussions on energy transition and urban decarbonization. It highlights the need for standardized reporting, which aligns with global disclosure frameworks like TCFD and ISSB.

📄 Abstract（原文）
ABSTRACT Urban electricity systems in Southern Africa are characterized by persistent grid unreliability, ageing infrastructure, and continued dependence on fossil fuels, despite substantial renewable energy potential. Hybrid energy systems (HES) have emerged as a pathway to enhance urban energy resilience, reduce costs, and support decarbonization. However, despite high urban electricity access, they remain underexplored relative to rural systems, limiting their role in addressing urban reliability challenges. This study presents a systematic review and cross‐country synthesis of urban‐rural HES deployments in Southern Africa between 2010 and 2025, focusing on dominant system configurations, modes of integration, sectoral applications, and techno‐economic and environmental performance. Findings show that PV–battery(–grid) systems dominate urban deployments, particularly in South Africa. More complex systems incorporating biomass, hydrogen, pumped hydro, or concentrated solar power remain scarce in urban contexts. Reported levelized cost of electricity ranges from $0.009 to $1.13/kWh, with a mean of $0.18/kWh. Net present cost spans $662 to $111.8 million, while financial savings range from $30,207 to $953,564 (14.4%–69.3%). Environmental performance is more consistent, with CO 2 emission reductions of 56.8%–90.3% and renewable fractions of 42–100%. Overall, the urban HES demonstrates strong decarbonization potential alongside improved economic viability, while highlighting the need for standardized reporting and supportive policy frameworks.
