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

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. Lead author Aniruddh Mohan and colleagues wanted to develop a method that evaluated the life-cycle costs and benefits for two battery-powered ridesource fleets and a gasoline-powered one.

NSF awards UCSD team $39M to improve integration of distributed energy resources into grid; EV batteries also

Green Car Congress

The major driver for the project is the need to decarbonize the electrical grid, protect it from cybersecurity attacks and make it more resilient. We will be replicating the entire California power grid on one campus. The goal is to make the testbed available to outside research teams and industry by 2025.

The Complex Calculus of Clean Energy and Zero Emissions

Cars That Think

Among the most articulate and almost certainly the wonkiest is Jesse Jenkins , a professor of engineering at Princeton University, where he heads the ZERO Lab—the Zero-carbon Energy systems Research and Optimization Laboratory, that is. power-grid transmission. Jesse Jenkins: In early 2021, given the results of the U.S.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

They wanted to see whether an electric vehicle could feed electricity back to the grid. The company’s president, Tom Gage , dubbed the system “vehicle to grid” or V2G. For the utilities, it promised an economical way of meeting rising demand for electricity. AC Propulsion’s experiment was timely.

How to Prevent Blackouts by Packetizing the Power Grid

Cars That Think

That need for balance is true of electric power grids, too. Spiking demand for electric heat collided with supply problems created by frozen natural-gas equipment and below-average wind-power production. The brown line shows the uncoordinated load from 1,000 electric water heaters for reference.

What Is Bidirectional Charging? Understanding the Benefits for Both Drivers and Businesses

EV Connect

Electric vehicle (EV) technology is advancing quickly. With each passing year, the potential of a road free of gas-guzzling cars looks more realistic. Batteries get more powerful , charging grows more efficient, and the path to an all-EV future becomes increasingly clear. The path doesn’t end there, however.
