Achieving climate neutrality for heavy-duty trucks is, in some ways, more challenging than for cars, but it is necessary since they contribute nearly 30 percent of climate emissions from road transport. This paper compares the social costs of diesel trucks, battery-only trucks (BAT), and battery overhead line trucks (BOT), which can charge while driving via overhead lines on electric motorways (e-roads). We conduct this comparison within a decision-making context where the future developments of battery costs, as well as overhead line investment and maintenance costs, are uncertain.
