长途重型货车（HGV）是碳排放的重要来源，约占英国总量的5%。如果英国要实现其净零排放的目标，就必须有一种零排放的替代品来替代传统的柴油动力HGV，这种替代品在21世纪40年代具有成本效益和广泛性。本文介绍了英国长途重型货车脱碳的两种解决方案的技术经济比较：电动HGV与电动道路系统（架空接触网）沿着主要道路网，燃料电池HGV与公共加油站供应绿色氢。技术经济分析的结果表明，架空接触网和兼容的HGV是更节能和更具成本效益的解决方案，以减少英国长途公路货运网络的碳，并将为基础设施提供商和车队运营商提供具有竞争力的投资回收期。通过这种方法，有可能收回英国政府目前从HGV获得的柴油税收的30-80%，具体取决于电价。相反，绿色氢解决方案将需要大量的政府补贴，特别是在21世纪30年代，以鼓励车队运营商购买和使用氢燃料电池HGV。
Long-haul Heavy Goods Vehicles (HGVs) are a significant source of carbon emissions, accounting for around 5% of the UK's total. If the UK is to meet its net zero mandate, it is vital to have a zero-emissions alternative to the traditional diesel-powered HGVs that is cost-effective and widespread in the 2040s. This paper presents a technoeconomic comparison of two solutions for decarbonising long-haul heavy goods vehicles in the UK: electric HGVs with an electric road system (overhead catenary) along the major road network, and fuel cell HGVs with public refuelling stations supplying green hydrogen. The results of the technoeconomic analysis show that overhead catenaries and compatible HGVs are the more energy-efficient and cost-effective solution to decar-bonise the UK's long-haul road freight network and would provide both the infrastructure provider and fleet operators with competitive payback periods. With this approach, there is a potential to reclaim 30-80% of the diesel tax revenue currently earned by the UK government from HGVs, depending on the price of electricity. Conversely, the green hydrogen solution will require substantial government subsidies, particularly during the 2030s, to encourage fleet operators to purchase and use hydrogen fuel cell HGVs.
