Abstract

German legislation sets forth that anthropogenic greenhouse gases must be net-zero from 2045 onward (KSG, 2019). In contrast, road freight transport is projected to grow significantly (BMVBS, 2008; BMVI, 2021). If sustainable solutions for road freight transport are not implemented swiftly, Germany will not be able to meet its climate protection targets. This study analyzes the potential of the eHighway system—an overhead contact line-based electrification of trucks—to reduce the road freight transport's carbon footprint. Based on more than three years of field test operation with over 500,000 real-world driven kilometers, we estimate the saving potential of directly emitted greenhouse gases from five pilot overhead contact line trucks that use the eHighway system (O-trucks). We conclude that with only a five percent electrified stretch of a trip, 14–17% of direct greenhouse gas emissions are saved compared to a conventional truck. We develop a scaling and comparison calculator for the estimation of directly emitted greenhouse gases of O-trucks. We argue that with an electricity mix based upon renewable energies and an appropriately extended eHighway network, road freight transport is capable of offering transport with net-zero greenhouse gas emissions. Based on a unique data set, we provide a benchmark for all further research in evaluating eHighway technology and for comparing it to alternative drive technologies.

电子高速公路对公路货运直接排放的温室气体的影响

德国法律规定，从 2045 年起，人为温室气体必须达到净零排放（KSG，2019 年）。相比之下，公路货运预计将大幅增长（BMVBS，2008 年；BMVI，2021 年）。如果不迅速实施公路货运的可持续解决方案，德国将无法实现其气候保护目标。本研究分析了 eHighway 系统--基于架空接触线的卡车电气化--在减少公路货运碳足迹方面的潜力。根据三年多的实地测试运行和超过 50 万公里的实际行驶里程，我们估算了使用 eHighway 系统的五辆试点高架接触线卡车（O 型卡车）直接排放的温室气体的减排潜力。我们得出的结论是，与传统卡车相比，只需行驶 5% 的电气化路段，就能减少 14% 至 17% 的直接温室气体排放。我们开发了一个缩放和比较计算器，用于估算 O 型卡车直接排放的温室气体。我们认为，如果采用以可再生能源为基础的电力组合，并适当扩展电子公路网，公路货物运输就能实现温室气体净零排放。基于独特的数据集，我们为评估电子公路技术的所有进一步研究以及将其与替代驱动技术进行比较提供了基准。

期刊介绍： Transport Policy is an international journal aimed at bridging the gap between theory and practice in transport. Its subject areas reflect the concerns of policymakers in government, industry, voluntary organisations and the public at large, providing independent, original and rigorous analysis to understand how policy decisions have been taken, monitor their effects, and suggest how they may be improved. The journal treats the transport sector comprehensively, and in the context of other sectors including energy, housing, industry and planning. All modes are covered: land, sea and air; road and rail; public and private; motorised and non-motorised; passenger and freight.
