アルジェリア・ワルグラの高日射地域を対象に、太陽光発電（PV）とPEM電解槽を用いたグリーン水素生成の技術的実現性を評価。1000m²のPVシステムを想定し、月別の水素生成量を試算した結果、年間約7,864kgの生成が可能であり、夏期にピークを迎えることが示された。このフレームワークは、同様の乾燥地帯における事前プロジェクト評価に再現可能である。
English
This study evaluates green hydrogen production using photovoltaic systems in Ouargla, Algeria, a high-solar-insolation arid region. Modeling a 1000 m² PV system with a PEM electrolyzer yields an annual hydrogen output of approximately 7,864 kg, with strong seasonal variation. The framework supports early-stage project assessment in similar climates.

📄 Abstract（原文）
Algeria, particularly its southern regions such as Ouargla, offers exceptional solar energy potential, with annual Global Horizontal Irradiance (GHI) exceeding 2,000 kWh/m2. This study evaluates the technical feasibility of green hydrogen production in Ouargla using Photovoltaic (PV) energy and a simplified modeling approach based on monthly satellite-derived solar data. A standalone 1000 m2 PV system with 20% efficiency was modeled, coupled with a Proton Exchange Membrane (PEM) electrolyzer operating at 65% efficiency. Key performance indicators, including monthly PV output, hydrogen production, electrolyzer utilization, and system efficiency, were calculated using standardized assumptions. The results indicate strong seasonal variation, with hydrogen yields peaking during summer months and total annual output reaching approximately 7,864 kg. These findings are consistent with earlier experimental and modeling studies conducted in similar arid environments and confirm Ouargla's suitability for pre-industrial green hydrogen initiatives. The study offers a replicable framework for early-stage project assessment and supports national strategies for energy diversification and low-carbon development in high-insolation regions.
