この論文は、欧州のグリーン水素需要の普及における空間的波及効果（近隣での採用が採用確率を高める効果）の重要性を実証的に示した。14,000以上の潜在的オフテイカーを分析し、波及効果はグリーン水素がコスト競争力を持たない場合に20倍以上大きくなることを発見。また、最も中心的なオフテイカーをターゲットにする政策が、コスト効率を最大41%改善することを示した。
English
This paper empirically demonstrates the critical role of spatial spillovers in green hydrogen diffusion across Europe, using a dataset of over 14,000 potential offtakers. The authors find that spillover effects are over 20 times stronger when green hydrogen is not cost-competitive, and that targeting the most central offtakers can improve policy cost-effectiveness by up to 41% (0.96 EUR/kg).

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文の空間的波及効果に基づく需要側政策の知見は、日本の水素基本戦略におけるハブ形成政策（例：京浜・中京工業地帯）に直接応用可能。欧州水素バンクのオークション形式の評価結果は、日本版水素基金の制度設計に示唆を与える。
In the global GX context
This paper provides novel empirical evidence on spatial spillovers in hydrogen diffusion, which is highly relevant for global hydrogen policy design. The finding that targeting central offtakers improves cost-effectiveness offers a clear policy lever for regions like the US (IRA) and Asia pursuing hydrogen adoption.
👥 読者別の含意
🔬研究者:Researchers studying technology diffusion, spatial spillovers, and hydrogen policy will find the empirical methodology and policy simulations valuable.
🏢実務担当者:Hydrogen project developers and utilities can use the identification of central offtakers to prioritize customer acquisition and optimize subsidy applications.
🏛政策担当者:Policymakers designing hydrogen demand-side instruments, such as auctions or subsidies, should consider spatial targeting to improve cost-effectiveness.
📄 Abstract（原文）
<title>Abstract</title> <p>Green hydrogen (H2) faces an implementation gap: demand significantly lags policy ambitions. Combining an installation-level model of green H2 demand with an original database of > 14,000 potential offtakers in Europe, we show that, conditional on diffusion patterns mirroring natural gas power generation (a historical analogue), demand-side spatial considerations are critical for closing this gap. Spatial spillovers - where local adoption increases adoption likelihood nearby - strongly shape diffusion, and their effect rises (> 20-fold) when green H2 is not cost-competitive. Spillover potential is concentrated in Central–Western Europe and hard-to-abate sectors: over half of the 10% most central installations are located in five German or Belgian industrial regions. Spatially-informed policies deliver superior outcomes: targeting the most central offtakers improves policy cost effectiveness by up to 41% (0.96 EUR kg-1) in a size, sector and cost-controlled setting and 15% (0.20 EUR kg-1) when following the European Hydrogen Bank auction format.</p>
