Study finds limiting warming to 2 °C would require at least a $200/t carbon tax globally

Green Car Congress

Lloyd Distinguished Service Professor in Economics, and José-Luis Cruz of Princeton University assesses the local social cost of carbon (LSCC) and how that cost aligns with the carbon reduction pledges countries made under the Paris Agreement. The price of carbon should then be set at this price, everywhere.

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.

Nornickel investigating using mining tailings to capture and store CO2

Green Car Congress

The dompany is also working to develop a methodology to take stock of carbon units captured this way. Silica and magnesium oxide contained in waste rock can absorb carbon dioxide during weathering (long-term exposure to air). In 2021, Nornickel extracted 41.2 mm) that looks like sand. This process is called mineralization.

Surrey team developing direct-air-capture CO2 to methanol process

Green Car Congress

Researchers at the University of Surrey (UK) are developing a process to capture carbon dioxide directly from the air and then use dynamic catalysis to create methanol—a valuable chemical that, made this way, could be carbon-negative. Its value could offset the cost of direct air capture.

Researchers develop wave-energy-driven CO2 reduction system for production of carbon-based liquid fuels

Green Car Congress

Finally, they present design guidelines for achieving a cost-effective, efficient, and large-scale wave-energy-driven CO 2 reduction system for liquid fuel production.

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 polymer membrane efficiently removes carbon dioxide from mixed gases; high permeability and selectivity

Green Car Congress

A team of researchers from North Carolina State University, SINTEF in Norway and the Norwegian University of Science and Technology, has developed a polymer membrane technology that removes carbon dioxide from mixed gases with both high permeability and high selectivity. A paper on their work is published in the journal Science.
