Fraunhofer analysis finds battery-electric trucks have energy cost advantage over hydrogen trucks

Green Car Congress

This is because hydrogen trucks have a decisive disadvantage: only about a quarter of the output energy flows into the drive, three quarters is lost through conversion losses. This is not likely to fail due to the resilience of the power grids—our trucks mainly load at midday and at night, when demand and prices are particularly low.

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

Green Car Congress

In the simulations, battery-powered vehicles, particularly the 40 kWh ones, needed more frequent and longer trips without passengers to get to recharging stations. They conclude that these results are specific to Chicago, and cities with different power grids and street layouts could have different assessments from full electrification.

The Complex Calculus of Clean Energy and Zero Emissions

Cars That Think

Jenkins has also helped push Congress to think more seriously about the power grid, releasing a report last year that showed that much of the 43 percent emissions reduction expected by 2030 would be squandered if the United States doesn’t double the pace of transmission upgrades. power-grid transmission.
