Abstract

Clean transport requires tailored energy carriers. For heavy-duty transportation, synthetic fuels are promising but must fulfil the key challenges of achieving carbon neutrality while reducing air pollution and ensuring scalability through compatibility with existing infrastructure. Here we show that hydroformylated Fischer–Tropsch (HyFiT) fuels composed of optimized alkane–alcohol blends simultaneously address these challenges. First, the design of the HyFiT fuel process flexibly closes the carbon cycle by employing biomass or carbon dioxide as feedstock, while being scalable through mature technologies. Second, fuel testing shows that HyFiT fuels comply with global fuel standards. Material compatibility is demonstrated for two standard sealing materials, enabling the retrofit of today’s vehicle fleets. Third, vehicle testing shows that HyFiT fuels substantially reduce combustion-induced particulate matter and nitrogen oxides. Fourth, a well-to-wheel life cycle assessment finds that HyFiT fuels enable the transition to net-zero greenhouse gas emissions, showing simultaneously a favourable profile in other environmental parameters. HyFiT fuels can thus complement electrification for heavy-duty transportation. For synthetic fuels to aid in a transition towards cleaner transportation, they must fulfil criteria related to scalability, compatibility with existing infrastructure and environmental impacts. Here the authors show that hydroformylated Fischer–Tropsch fuels comprising optimized alkane–alcohol blends are promising candidates when judged by these metrics.

利用加氢甲酰化费托燃料实现重型交通工具的碳中和清洁推进
清洁运输需要量身定制的能源载体。对于重型运输来说,合成燃料前景广阔,但必须满足以下关键挑战:在减少空气污染的同时实现碳中和,以及通过与现有基础设施的兼容性确保可扩展性。在这里,我们展示了由优化的烷烃-酒精混合物组成的加氢甲酰化费托(HyFiT)燃料可以同时应对这些挑战。首先,HyFiT 燃料工艺的设计通过采用生物质或二氧化碳作为原料,灵活地封闭了碳循环,同时可通过成熟技术进行扩展。其次,燃料测试表明 HyFiT 燃料符合全球燃料标准。两种标准密封材料的材料兼容性得到了验证,从而使当今的车队能够进行改装。第三,车辆测试表明, HyFiT 燃料大大减少了燃烧引起的颗粒物和氮氧化物。第四,一项 "从油井到车轮 "的生命周期评估发现, HyFiT 燃料能够实现温室气体净零排放,同时在其他环境参数方面也表现出良好的特性。因此,HyFiT 燃料可作为重型运输电气化的补充。
