Analysis of the financial viability of high-powered electric roadways: A case study for the state of Indiana

Comparing costs and climate impacts of various electric vehicle charging systems across the United States

“…Specifically, BSS has large capital costs, which can be reduced on a per kilowatt-hour (kWh) dispensed basis through lower battery prices (90–150 USD/kWh 22 ) and greater utilization. Moreover, DWPT exhibits a wide range of capital costs (0.94–5.4 million USD/lane-kilometer 11 , 12 , 23 ) across different scenarios due to the early-development status of the technology. Consequently, DWPT can have the highest or the lowest capital cost per kWh dispensed (Supplementary Fig.…”

“…The suitability of the sites for high-power charging stations was evaluated based on their proximity to grid interconnections and minimum EV charging utilization. Since load growth from widescale EV adoption was expected to require new substations 23 , the location of grid interconnections was modeled as transmission lines with voltages under 200-kV rather than existing substations 52 . Site locations within 6-km of grid interconnections 53 , based on the 95th percentile of existing DCFC sites, were deemed to be within the maximum proximity to grid interconnections.…”

“…For the optimistic scenarios, the low estimate from Limb et al (2019) was used for rural roads, while the high estimate was used for urban roads 11 . As for the baseline and conservative scenarios, the electronics cost of 1.6 million USD per km (adjusted to 2022 USD 63 ), as reported by Haddad et al (2022), was employed 23 . The conservative civil cost for urban roads was derived from the 1st-of-a-kind case in Trinko et al (2022), with a lower contingency cost of 10% compared to the original 30% 12 .…”

“…The baseline urban civil cost was also adapted from Trinko et al (2022), incorporating a combination of the 1st-of-kind and nth-of-a-kind cases, which is further detailed in Supplementary Table 2 12 . Regarding the civil costs for rural roads, the nth-of-kind case from Trinko et al (2022) was utilized for the baseline scenario, while the estimate from Haddad et al (2022) was adapted (without substation) for the conservative scenario 23 .…”

Application of Real-Life On-Road Driving Data for Simulating the Electrification of Long-Haul Transport Trucks

“…Electrified highways (e-Hwys) are a technology potentially suitable for the decarbonization of road transportation [1][2][3][4]. e-Hwys work by having installed infrastructure which supplies electricity directly from the electric grid to vehicles as they travel along the road, traditionally with catenary systems, or more recently, via dynamic wireless power transfer (DWPT) [3,5]. e-Hwys thus shift the focus to dynamic power rather than the more conventional electric vehicle (EV) situation which relies on the storage capacity of a battery.…”
