Columbia University engineers make breakthrough in understanding electroreduction of CO2 for conversion to electrofuels

Green Car Congress

Recent research in electrocatalytic CO 2 conversion points the way to using CO 2 as a feedstock and renewable electricity as an energy supply for the synthesis of different types of fuel and value-added chemicals such as ethylene, ethanol, and propane. Their paper is published in Proceedings of the National Academy of Sciences (PNAS).

New electrocatalyst converts CO2 into ethanol, acetone, and n-butanol with high efficiency

Green Car Congress

The electrocatalytic conversion of CO 2 using renewable energy could establish a climate-neutral, artificial carbon cycle. Conversion into liquid fuels would be advantageous because they have high energy density and are safe to store and transport. These could then be burned as needed. Credit: Angewandte Chemie.

Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

Researchers from Northwestern University and Princeton University have explored the impact on US air quality from an aggressive conversion of internal combustion vehicles to battery-powered electric vehicles (EVs). No matter how the power is generated, the more combustion cars you take off the road, the better the ozone quality.
