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

Green Car Congress

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. The analysis indicated that electrified fleets had 40-45% lower greenhouse gas costs per trip compared to the gasoline-powered version.

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Yi Cui has developed nanoparticle copper hexacyanoferrate (CuHCF) battery cathode materials that demonstrate long cycle life and high power for use in grid storage applications. Potassium will just zoom in and zoom out, so you can have an extremely high-power battery. A team at Stanford led by Prof. —Yi Cui.

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

Cars That Think

It occurred in the wake of the California electricity crisis of 2000 and 2001, when mismanaged deregulation, market manipulation, and environmental catastrophe combined to unhinge the power grid. AC Propulsion’s president, Tom Gage, explains the company’s vehicle-to-grid technology at a 2001 conference in Seattle.

Opinion: Debunking the mythsWhy fuel cell electric vehicles (FCEVs) are viable for the mass market

Green Car Congress

Hydrogen is the most abundant element in the Universe but, on earth, it must normally be extracted from water or organic compounds. This renewable production capacity is increasingly important to ensure the existing power grid can accept more renewable sources. It’s time to debunk a number of myths.
