本論文は、2050年におけるアルジェリアの電力・水素輸送インフラのコスト最適設計を、オープンソースのPyPSA-Earthを用いた時空間分解型の部門結合モデルで分析する。既存天然ガスパイプラインの水素転用コスト、国内電力需要、水素輸出量を変化させ、水素輸送・送電・再エネ容量の空間分布を評価した。水素輸送は一貫して南北方向となるが、転用コストが低いと再エネと電解が南部へ移り、高いと北部集中と送電依存が強まる。輸出志向インフラと国内需要のトレードオフを明らかにする。
English
This study models the cost-optimal design of Algeria's electricity and hydrogen transport infrastructure in 2050 using the open-source PyPSA-Earth sector-coupled framework. It analyzes repurposing existing natural gas pipelines for hydrogen under varying repurposing costs, domestic demand, and export volumes. Hydrogen transport consistently runs south–north, but low repurposing costs shift renewables and electrolysis southward, while high costs concentrate capacity in the north and increase reliance on transmission. The work reveals trade-offs between export-oriented infrastructure and domestic needs.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
水素サプライチェーンと既存インフラ転用のコスト評価は、日本の水素輸入戦略や海外水素調達の検討に間接的に参考となる。ただし対象はアルジェリアに限定され、日本の制度・政策との直接の接点は薄い。
In the global GX context
As global hydrogen trade and export-oriented infrastructure scale up, this paper offers a replicable open-source modeling approach for assessing pipeline repurposing and the trade-offs between export and domestic decarbonization—relevant to transition finance and cross-border hydrogen supply chain planning.

📄 Abstract（原文）
This work investigates the cost-optimal design of Algeria's electricity and hydrogen transport infrastructure in 2050. Using the open-source PyPSA-Earth framework, a spatially and temporally resolved sector-coupled energy system model is employed to analyse the repurposing of existing natural gas pipelines for hydrogen use. The extent and spatial distribution of hydrogen transport, electricity transmission and renewable energy capacities are analysed under varying repurposing costs, domestic electricity demand, and hydrogen export volumes. Across the investigated scenarios, hydrogen transport exhibits a recurring south–north orientation, although its capacity varies considerably with export volumes and repurposing costs. Favourable repurposing costs enable renewable generation and electrolysis to shift towards southern regions, whereas higher pipeline costs concentrate renewable capacity in key north-central and north-eastern regions and increase reliance on electricity transmission. The results demonstrate the interdependence of renewable deployment, domestic demand, and hydrogen exports and reveal trade-offs between export-oriented infrastructure and evolving domestic needs.
