本研究は、欧州の脱炭素困難部門でのグリーン水素導入促進に向け、水素補助金制度と電解槽のエネルギーシステム統合の効果を分析。補助金なしでは2050年に16.3 Mt H2/年の需要だが、固定プレミアムにより最大100.2 Mt H2/年に増加。ただし、高い補助金は技術置換や補助金終了後の逆転リスクにより削減効率を低下させる。
English
This study analyzes how hydrogen subsidies and energy-system integration of electrolysers can promote green hydrogen adoption in European hard-to-abate sectors. Without subsidies, hydrogen demand reaches 16.3 Mt H2/yr in 2050, but fixed premiums increase uptake to up to 100.2 Mt H2/yr, with total subsidy costs ranging from €96B to €4,201B. However, higher support reduces abatement efficiency due to technology replacement and post-subsidy reversion risks.

📄 Abstract（原文）
This study investigates how hydrogen support schemes and energy-system integration of electrolysers can promote the market-driven adoption of electrolytic hydrogen in European hard-to-abate sectors. We soft-link the Balmorel energy system model with the HyADOPTS technology-diffusion model to combine spatially resolved renewable-electrolyser operation with sec-tor-specific investment behaviour. Without subsidies, system integration and emission taxes alone enable $\mathbf{1 6. 3} \mathrm{Mt} \mathrm{H}_{2} / \mathbf{y}$ of green hydrogen demand in 2050, yet substantial fossil use remains in many sectors $\left(704 \mathrm{Mt} \mathrm{CO}_{2} / \mathrm{y}\right.$ in 2050). Policy support through fixed premiums increases sectoral uptake: modest premiums benefit in smaller industrial niches, such as refining and fertiliser industries, whereas wide-scale adoption into aviation and chemical sectors requires either high premiums or long durations to achieve adoption. Total hydrogen demand increases to 23.9$100.2 \mathrm{Mt} \mathrm{H}_{2} / \mathrm{y}$ across scenarios, depending on subsidy spending, ranging from 96 B€ to 4201 B€ total cost. However, higher support volumes reduce abatement efficiency due to technology replacement effects and post-subsidy reversion risks.
