摘要

可再生燃料有助于减少交通运输中的碳排放。为了为规划决策提供信息,本文估算了挪威长途卡车运输、短途海运和中程航空货运中用可再生氢、氨或费托电子燃料替代化石燃料的碳减排成本。我们通过应用可再生燃料价值链的整体成本模型来做到这一点。我们比较了各个运输部门的减排成本,并分析了价值链上的政策干预(如碳定价、补贴和降低风险政策)如何影响碳减排成本。根据电力来源、运输部门和燃料类型的不同,我们估计2020年的减排成本为793 - 1598欧元/吨二氧化碳,2050年为-11-675欧元/吨二氧化碳。氢的成本每公斤降低1欧元(例如通过补贴),目前氢动力卡车的碳减排成本将降低95欧元/吨二氧化碳,电子燃料动力航运的碳减排成本将降低133欧元/吨二氧化碳,电子燃料动力航空的碳减排成本将降低143欧元/吨二氧化碳。我们进一步表明,加权平均资本成本的降低大大降低了减排成本,特别是可再生氢,因为它的相对资本强度。

Carbon abatement costs for renewable fuels in hard-to-abate transport sectors

Renewable fuels can help to reduce carbon emissions from transportation. To inform planning decisions, this paper estimates carbon abatement costs of replacing fossil fuels with renewable hydrogen, ammonia, or Fischer–Tropsch e-fuel in Norwegian freight transport across long-haul trucking, short-sea shipping, and medium-haul aviation. We do this by applying a holistic cost model of renewable fuel value chains. We compare abatement costs across transport sectors and analyze how policy interventions along the value chains – such as carbon pricing, subsidies, and de-risking policies – impact carbon abatement costs. We estimate abatement costs of 793–1,598 €/tCO2 in 2020 and -11–675 €/tCO2 in 2050, depending on the electricity source, transport sector, and type of fuel. A 1 €/kg reduction in the cost of hydrogen - e.g. through a subsidy - lowers present-day carbon abatement cost by 95 €/tCO2 for hydrogen-powered trucking, 133 €/tCO2 for e-fuel-powered shipping, and 143 €/tCO2 for e-fuel-powered aviation. We further show that reductions in the weighted average cost of capital materially decrease abatement cost, particularly for renewable hydrogen due to its relative capital intensity.
