本論文は、都市規模での水素導入を評価するため、ETEMモデルを拡張し、モントリオール都市圏に適用。完全なカーボンニュートラル制約下では、2050年までに水素が最終エネルギー消費の約7%を占め、生産量は33PJ超に達するが、導入は重工業や電化困難な運輸部門に集中。気候制約が強まると、電気分解やCCSを活用した生産へ移行し、2040年以降に導入が加速。残存排出を相殺するため、最低1MtCO2/年のDACが必要と示す。
English
This paper extends the ETEM model to assess hydrogen integration in metropolitan energy systems, applying it to Montréal. Under full carbon neutrality, hydrogen reaches ~7% of final energy by 2050, with production exceeding 33 PJ, but uptake is concentrated in heavy industry and hard-to-electrify transport. As constraints tighten, production shifts to electrolysis and CCS, with deployment rising after 2040. Carbon neutrality requires at least 1 MtCO2/year of direct air capture to offset residual emissions.

📄 Abstract（原文）
Low-carbon hydrogen is increasingly considered a key option for decarbonizing hard-to-abate sectors, yet most transition analyses are conducted at national or global scales, with limited attention to metropolitan energy systems where climate policies are implemented. This paper examines how hydrogen can contribute to urban decarbonization under multi-level climate governance by extending the Energy Technology Environment Model (ETEM) to integrate full hydrogen supply chains and applying a structured downscaling approach to translate national and provincial data to the metropolitan scale. The framework is applied to the Montréal Metropolitan Community (CMM), a member of the C40 Cities network, to evaluate hydrogen deployment under different decarbonization scenarios. Results show that under full carbon neutrality constraints, hydrogen reaches approximately 7% of total final energy consumption by 2050, with total production exceeding 33 PJ, yet uptake remains concentrated in heavy industry and hard-to-electrify transport, underscoring hydrogen's role as a targeted complement to electrification rather than a dominant energy carrier. As climate constraints tighten, hydrogen production shifts toward electrolysis and CCS-enabled pathways, with deployment increasing significantly after 2040. Carbon neutrality further requires a minimum direct air capture capacity of 1 MtCO₂/year to offset residual emissions from sectors where abatement through fuel switching alone is technically infeasible. The proposed modeling framework is designed to be adaptable to other metropolitan regions and C40 cities with similar data infrastructure, offering a structured approach for assessing hydrogen integration in urban energy transitions.
