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.

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.

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.

Highview Power and Encore Renewable Energy to co-develop the first long-duration, liquid-air energy storage system in US

Green Car Congress

With Highview Power’s liquid air energy storage solution, excess or off-peak electricity is used to clean and compress air which is then stored in liquid form in insulated tanks at temperatures approaching -320 ?F

CESifo: EVs not the best option for reduction in on-road CO2 in Germany given power mix

Green Car Congress

According to a new study published by the ifo Institue Center for Economic Studies (CESifo) in Germany, EVs will barely help cut CO 2 emissions in the country over the coming years, as the introduction of electric vehicles does not necessarily lead to a reduction in CO 2 emissions from road traffic given the current power generation mix.
