本研究は、ゼロエミッション大型トラックと電力系統の相互依存を考慮した部門連成発電拡張計画モデルを開発し、2050年ネットゼロ達成における水素燃料電池トラックとバッテリー電気トラックのコスト最適性を比較した。その結果、バッテリートラックが最大47%のコスト削減で最適であり、水素価格が1ドル/kg未満にならない限り水素は競争力を持たないことを示した。また、ディーゼル価格の20〜50セント/L上昇が両技術の普及に有効であると示した。
English
This study develops a sector-coupling generation expansion planning model that captures the interdependence between zero-emission heavy-duty trucks and the electricity grid, comparing hydrogen fuel-cell and battery-electric trucks for net-zero by 2050. Results show battery trucks are cost-optimal with up to 47% savings over hydrogen, and hydrogen only reaches parity when consumer prices fall below $1/kg. Diesel price increases of 20-50 cents/L are sufficient to promote decarbonization for both technologies.

In the global GX context
This paper contributes to global transition finance and climate disclosure by providing quantitative evidence on the cost-effectiveness of zero-emission trucking pathways, relevant for TCFD/ISSB scenario analysis and corporate fleet decarbonization strategies. It highlights the critical role of carbon pricing and hydrogen price targets, informing policy design and investment decisions in the transport sector.

📄 Abstract（原文）
Abstract The global energy system must deeply decarbonize as soon as possible to avert the worst consequences of climate change, including the transportation sector, which accounts for 23% of global emissions. Several technological options have been proposed to decarbonize diesel-consuming heavy-duty vehicles, including hydrogen fuel-cell trucks and battery-electric trucks. This study models the newfound interdependency between zero-emission heavy-duty vehicles and the electricity grid, in a sector-coupling generation expansion planning model, to achieve net-zero emissions in 2050. We demonstrate that when considering the electric grid impacts of zero-emission trucks, battery trucks offer the cost optimal approach, with up to 47% savings compared to the hydrogen alternative. We also show that current hydrogen price targets are too high to achieve decarbonization via hydrogen fuel-cell trucks; parity with batteries is only achieved when hydrogen prices for the consumer fall below $1/kg. We show that abatement costs are within the scope of current carbon pricing schemes, where diesel fuel prices must rise by 20–50¢/L to promote decarbonization of heavy-duty trucking for both BETs and HFCTs.
