Decarbonising heavy-duty truck fleets is essential for meeting the European Union’s ambitious transport-related emission reduction targets. This paper presents the techno-economic and environmental modelling results of zero-or-low-emission truck fleets (ZLETs). ZLETs like battery electric and hydrogen fuel-cell electric trucks are compared against diesel truck fleets. Key parameters used to compare ZLETs against diesel trucks are total cost of ownership (TCO) and total carbon abatement (TCA) cost. TCO and TCA analysis are evaluated for three different electricity and hydrogen production scenarios: off-grid, on-grid, and hybrid (use of both dedicated renewables and grid electricity adhering to renewable energy directive-II). Results show TCO of both ZLETs is higher than diesel trucks for an off-grid scenario. Battery trucks show the lowest TCO for on-grid scenario due to the continuous availability of cheap grid electricity and no large-scale energy storage cost. In contrast, fuel-cell trucks are cheaper than battery trucks in a hybrid scenario due to the relatively low cost of large-scale hydrogen storage compared to electricity in expensive onsite batteries. Both ZLETs have minimum TCO for on-grid scenario. However, higher well-to-wheel emissions can be abated using a hybrid scenario. This shows only when cheap renewable electricity is available continuously without large-scale battery storage, battery trucks are more cost-effective and truly green choice over fuel-cell trucks.
