Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

But the cars and SUVs used in these situations drive more miles each year than a typical personal vehicle, contributing a higher proportion of greenhouse gases to the environment. In the simulations, battery-powered vehicles, particularly the 40 kWh ones, needed more frequent and longer trips without passengers to get to recharging stations.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

Monique closes her EV’s fueling port and heads onto the highway with enough stored energy to drive 640 kilometers (400 miles). The battery in her EV is a variation on the flow battery , a design in which spent electrolyte is replaced rather than recharged. An example, she says, is the task of balancing energy flows in the power grid.
