重型道路运输仍然是一个难以脱碳的行业，因为长途卡车运输的全面电气化目前受到能量密度和充电基础设施的限制。因此，氢、生物柴油和电子燃料等替代燃料正受到越来越多的关注。与此同时，水泥工业是不可避免的、与工艺相关的二氧化碳排放的主要来源，这为利用捕获的工业二氧化碳作为电子燃料生产的原料提供了机会。本研究以奥地利一家水泥厂捕获的二氧化碳为基础案例，评估了电子甲醇和费托（FT）柴油的生产。研究分析了多种系统配置，包括欧洲不同地区的电力供应方案，以及生物源二氧化碳与化石源二氧化碳的使用。研究采用了一个结合过程模拟、技术经济分析和生命周期评估的综合框架，对两种燃料路径进行比较。结果表明，电子燃料的气候影响高度依赖于电力结构。当使用非可再生电力时，气候影响比化石柴油高100-440%。相比之下，基于风能的奥地利情景实现了最低影响，与化石柴油相比减少了44-50%。总体而言，在当前欧洲能源条件下，基于水泥厂的电力转液体概念在近期至中期提供的减排潜力有限，且其气候效益主要源于生物源二氧化碳、高工艺效率和低碳电力。研究进一步强调了两种燃料之间的关键差异，其中FT柴油是一种经认证的直接替代燃料，而电子甲醇仍需技术和监管验证，这凸显了进行技术特定和系统层面评估的必要性。

Heavy-duty road transport remains a challenging sector to decarbonize, as full electrification of long-distance trucking is currently constrained by limitations in energy density and charging infrastructure. Alternative fuels such as hydrogen, biodiesel, and e-fuels are thus gaining increasing attention. In parallel, the cement industry is a major source of unavoidable, process-related CO2 emissions, offering an opportunity to use captured industrial CO2 as a feedstock for e-fuel production. This study evaluates the production of e-methanol and Fischer-Tropsch (FT) diesel from captured CO2 at an Austrian cement plant as a base case. Several system configurations are analyzed, including different electricity supply options across Europe and the use of biogenic versus fossil CO2. An integrated framework combining process simulation, techno-economic analysis, and life-cycle assessment is applied to compare both fuel pathways. Results show that the climate impact of e-fuels is highly dependent on the electricity mix. When non-renewable electricity is used, climate impacts are 100-440% higher than those of fossil diesel. In contrast, a wind-based Austrian scenario achieves the lowest impact, corresponding to a 44-50% reduction compared to fossil diesel. Overall, cement-plant-based power-to-liquid concepts offer limited near- to mid-term mitigation potential under current European energy conditions and deliver climate benefits primarily when based on biogenic CO2, high process efficiencies, and low-carbon electricity. The study further highlights key differences between the fuels, with FT-diesel being a certified drop-in fuel, while e-methanol still requires technical and regulatory validation, underscoring the need for technology-specific and system-level assessments.
