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.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

INFINITI says new gasoline-generated EV system (Nissan e-POWER) central to electrification strategy

Green Car Congress

These include fully-electric systems, as well as a gasoline-generated EV system (known as e-POWER at Nissan, earlier post ) in which a gasoline engine generates electrical power stored in a battery (series hybrid), which can then be delivered to all four wheels through a pair of high-output electric motors.

Fraunhofer suggests e-scooters as application for its magnesium hydride paste hydrogen storage technology

Green Car Congress

kWh/liter—about 10 times the capacity of Li-Ion batteries. The award-winning POWERPASTE technology is patented (EU, US) and offers advantages over other energy storage technologies, in particular in the power range from 100 W to 10 kW, Fraunhofer researchers said. It has a hydrogen capacity of about 10 mass-% (i.e.
