Argonne study finds BEVs can have lowest scheduled maintenance costs, but highest cost of driving

Green Car Congress

Researchers at Argonne National Laboratory, with colleagues from Lawrence Berkeley, Oak Ridge, and National Renewable Energy labs, and the University of Tennessee, have published a comprehensive analysis of the total cost of ownership (TCO) for 12 sizes of vehicles ranging from compact sedans up to Class 8 tractors with sleeper cabs.

NREL report finds electrified heavy-duty vehicle powertrains could provide lower total cost of ownership than diesel under certain conditions

Green Car Congress

A new total cost of ownership (TCO) study from the National Renewable Energy Laboratory (NREL) finds that battery-electric and fuel-cell electric commercial trucks could be economically competitive with conventional diesel trucks by 2025 in some operating scenarios. —Chad Hunter, lead author of the report and former NREL researcher.

Lux Research: fuel cell vehicles lag other drivetrains in terms of cost of ownership; ICE and HEV lowest cost

Green Car Congress

Based on an analysis of various cost of ownership scenarios for various drivetrains, including internal combustion engine (ICE) gasoline and diesel; hybrid (HEV); battery-electric (EV); plug-in hybrid electric (PHEV); and fuel cell vehicles, Lux Research concludes that fuel cell vehicles (FCVs) are “ solidly in a laggard position. ”.

DOE labs study on costs and benefits of new transportation technologies the most comprehensive to date

Green Car Congress

A new study published by US Department of Energy’s (DOE) Argonne National Laboratory offers the most complete understanding yet of the costs of owning and operating a vehicle, and how those costs vary by powertrain, from the conventional to the cutting-edge. Overall, hybrid electric vehicles tend to be the lowest-cost powertrain.

BMW i Ventures invests in GenXComm to increase speed and lower cost of 5G rollout; microphotonics-based full-duplex, high-speed communication

Green Car Congress

GenXComm’s Simultaneous Self Interference Cancellation (S-SIX) technology combines hybrid analog and digital interference cancellation to be able to provide a wide-band, tunable true full duplex radio within a compact subsystem. This is computationally intensive, increasing system size and resource utilization.

MIT team proposes SCR emission control for hybrid aviation turbines; reducing NOx by 95%

Green Car Congress

SCR systems would reduce NO x emissions at the cost of increased aircraft weight and specific fuel consumption due to the pressure drop in the core stream induced by the catalyst. Furthermore, SCR systems require ultra-low sulfur (ULS) fuel to prevent catalytic fouling. —Prashanth et al. Prakash Prashanth, Raymond L. Speth, Sebastian D.
