欧州・アフリカ間のエネルギー市場モデルを用いて、H2Globalメカニズムがグリーン水素・アンモニア・メタノールのコストギャップを埋める効果を分析。2030年には全経路が非競争的だが、2050年には最大450TWhの貿易が競争的になる可能性を示し、初期段階の支援が市場形成に重要と結論。
English
This study couples European-African energy markets to analyze the H2Global mechanism's role in bridging the cost gap for green hydrogen, ammonia, and methanol. It finds no cost-competitiveness in 2030, but early support enables market entry and trade volumes up to 450 TWh by 2050, concluding H2Global is a key instrument for overcoming the initial chicken-and-egg problem.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は水素基本戦略を掲げ、国際サプライチェーン構築を目指すが、コストギャップが課題。本論文のH2Global型メカニズムの分析は、日本の水素調達政策（例：GH2等）に示唆を与える。ただし、欧州・アフリカ間の設定であり、そのまま日本に適用可能かは要検討。
In the global GX context
This paper provides rigorous modeling evidence on how auction-based subsidy mechanisms (H2Global) can bridge the green hydrogen cost gap, directly informing global policy discussions under the EU hydrogen strategy and the emerging international hydrogen certification frameworks. It offers a replicable framework for other regions considering similar market creation instruments.
👥 読者別の含意
🔬研究者:Energy system modelers can adopt the coupled-market framework to analyze other cross-border hydrogen corridors.
🏢実務担当者:Corporate strategists in hydrogen and Power-to-X sectors can use the cost data and market projections to inform investment timing.
🏛政策担当者:Governments designing hydrogen subsidy or auction schemes (e.g., EU, Japan, Australia) can learn from the H2Global mechanism's design and impact estimates.
📄 Abstract（原文）
<title>Abstract</title> <p>Achieving climate neutrality requires large-scale production of green hydrogen and its derivatives. A persistent cost gap between producers and offtakers, however, impedes market growth. Our study couples European-African energy markets to analyse the role of the H2Global mechanism in bridging this gap, employing sector-coupled energy models. We find that no analysed pathway is cost-competitive in 2030, with African export costs (140-229 €/MWh) exceeding European willingness to pay (40-100 €/MWh) for hydrogen, ammonia, and methanol. The required annual funding ranges between 0.6 and 11.4 billion €. By 2050, early-stage support enables a market entry and the ramp-up of a hydrogen and Power-to-X economy: trade volumes of up to 236 TWh become cost-competitive, potentially reaching 450 TWh through reinvested savings. We conclude that, although ambitious European climate targets are the main reason for market ramp-up, the H2Global mechanism is a key and cost-effective instrument for overcoming the initial 'chicken-and-egg' problem, enabling market creation and ramp-up.</p>
