太陽光発電による水電解グリーン水素製造を技術・経済・環境の三側面から統合的に最適化する文献レビュー。高効率PV、先進電極触媒、システム統合が太陽光-水素変換効率を高め、PV・電解装置コスト低減と適切な立地・規模設計が水素均等化コストを下げることを示す。LCAでは化石由来水素に比べGHG排出が大幅に削減される。統合的アプローチの重要性を強調する。
English
A PRISMA-based qualitative review synthesizing 2015–2025 studies on solar-powered green hydrogen. It finds that high-efficiency PV, advanced electrocatalysts, and system integration raise solar-to-hydrogen efficiency, while falling PV/electrolyzer costs, optimal sizing, and siting lower the levelized cost of hydrogen. LCA evidence shows substantial GHG reductions versus fossil hydrogen, and an integrated optimization approach is essential for balancing performance, cost, and sustainability.

📄 Abstract（原文）
The increasing urgency of climate change mitigation and the global transition toward sustainable energy systems have accelerated interest in green hydrogen as a clean energy carrier. Green hydrogen produced through water electrolysis powered by solar energy offers a promising pathway to decarbonize industrial, transportation, and energy storage sectors. However, challenges related to energy conversion efficiency, production cost, and environmental sustainability remain major barriers to large-scale deployment. This study aims to analyze and optimize green hydrogen production from solar-powered water electrolysis by integrating technical, economic, and environmental perspectives. The research employs a qualitative literature review method, synthesizing peer-reviewed studies published between 2015 and 2025. Data were collected through a systematic review process following the PRISMA framework and analyzed using thematic content analysis. The findings indicate that technical optimization through high-efficiency photovoltaic systems, advanced electrocatalysts, and system integration can significantly improve solar-to-hydrogen efficiency. Economic analyses reveal that reductions in photovoltaic and electrolyzer costs, optimal system sizing, and strategic site selection are key to lowering the levelized cost of hydrogen. Environmentally, life cycle assessments demonstrate substantial greenhouse gas emission reductions compared to fossil-based hydrogen pathways. An integrative optimization approach is essential to ensure balanced performance, cost-effectiveness, and sustainability.
