New system for more efficient CO2 electrolysis to hydrocarbon products

Green Car Congress

A team of researchers from Canada and the US has developed a system that quickly and efficiently converts carbon dioxide into simple chemicals via CO 2 electrolysis. The electrode architecture enables production of two-carbon products such as ethylene and ethanol at current densities just over an ampere per square centimeter.

UD team devises CO2 direct air capture device powered by hydrogen for HEMFCs

Green Car Congress

University of Delaware engineers have demonstrated an effective way to capture 99% of carbon dioxide from the ambient air feed to an hydroxide exchange membrane fuel cell (HEMFC) air using a novel electrochemical system powered by hydrogen. However, HEMFC performance is adversely affected by CO 2 present in the ambient air feed.

New highly efficient catalyst for photoelectrochemical CO2 reduction toward methane

Green Car Congress

The work, presented in a paper in Proceedings of the National Academy of Sciences (PNAS), offers a unique, highly efficient, and inexpensive route for solar fuels synthesis. The researchers think that it could be recycling smokestack carbon dioxide into clean-burning fuel within 5-10 years. —lead author Baowen Zhou.
