日本語

本研究は、ナミビア・リューデリッツ地域における大規模グリーン水素生産の適地を評価するため、AHPとGISを統合した手法を提案。日射量、風速、土地利用、インフラ近接性などの基準を重み付けし、空間分析を実施。その結果、約20%が高適性、68%が中適性と評価され、政策立案や投資計画に科学的根拠を提供する。

English

This study uses an integrated AHP-GIS approach to assess site suitability for large-scale green hydrogen production in Lüderitz, Namibia. Criteria such as solar irradiance, wind speed, land use, and infrastructure proximity were weighted and overlaid. Results show ~20% high suitability and ~68% moderate suitability, providing a scientific basis for policy and investment planning.

📄 Abstract（原文）

Namibia’s vast renewable energy potential positions it as a strategic location for green hydrogen production, a key vector in advancing global decarbonization objectives. Nevertheless, identifying optimal production sites remains a complex and multidimensional challenge. This study presents a comprehensive techno-economic and spatial assessment to determine the most suitable areas for large-scale green hydrogen production in Lüderitz, Namibia. The analysis employs the Analytic Hierarchy Process integrated with Geographic Information System techniques to evaluate and spatially prioritize potential sites. Critical criteria, including solar irradiance, wind velocity, land use, and proximity to essential infrastructure, were systematically weighted and overlayed to generate suitability classifications. The results indicate that approximately 20% of the study area exhibits high suitability, 68% exhibits moderate suitability, 8% exhibits marginal suitability, and 4% is unsuitable for the development of integrated wind and solar energy. These findings provide a robust scientific basis for guiding policy formulation, investment planning, and the spatial optimization of Namibia’s emerging green hydrogen industry.
