Researchers convert atmospheric CO2 to carbon nanofibers and nanotubes for use as anodes in Li-ion and Na-ion batteries

Green Car Congress

Researchers from George Washington University and Vanderbilt University have demonstrated the conversion of atmospheric CO 2 into carbon nanofibers (CNFs) and carbon nanotubes (CNTs) for use as high-performance anodes in both lithium-ion and sodium-ion batteries. —Stuart Licht. —Licht et al.

UW researchers discover major lithium resource in Wyoming; potential integrated brine production/CO2 storage system

Green Car Congress

Researchers at the University of Wyoming Carbon Management Institute (CMI) discovered a major new lithium resource near Rock Springs during a geological carbon dioxide storage site characterization project sponsored by the US Department of Energy. Presently, the US imports more than 80% of the lithium used domestically.

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Researchers at the Leibnitz Institute for Catalysis (Rostock, Germany) have introduced a new approach to hydrogen storage that is based on simple salts of formic acid and carbonic acid. A fundamental problem with the use of these storage materials is the separation of the carbon dioxide formed when the hydrogen is released.

PARC building cleantech portfolio; co-extrusion printing of novel battery electrodes and carbon-neutral renewable liquid fuels from atmospheric CO2

Green Car Congress

Carbon-neutral liquid fuel. As long as the energy for the process is renewably generated, PARC notes, the overall process is carbon-neutral. The technique uses a solvent such as sodium or potassium hydroxides, converted by reacting with CO 2 to aqueous carbonates or bicarbonates. Electrodes.

Sandia progressing to demo stage with supercritical CO2 Brayton-cycle turbines; up to 50% increase in efficiency of thermal-to-electric conversion

Green Car Congress

Research focuses on supercritical carbon dioxide (S-CO 2 ) Brayton-cycle turbines, which typically would be used for bulk thermal and nuclear generation of electricity, including next-generation power reactors. The supercritical properties of carbon dioxide at temperatures above 500 °C and pressures above 7.6 Resources.

NSF to award up to $13M for fundamental work on sustainable production of electricity and transportation fuels

Green Car Congress

Processes for sustainable energy production must be environmentally benign, reduce greenhouse gas production, and utilize renewable resources. Advanced systems such as lithium-air, sodium-ion, as well as lithium-ion with new cathode chemistries are appropriate. The duration of unsolicited awards is typically three years.

Japanese carmakers still ‘most sustainable’

Green Cars News

A focus on tailpipe CO2 emissions has distracted away from the impact of car production, suggests Professor Frank Figge who co-authored the ‘Sustainable Value in Automobile Manufacturing’ study. Never before has it been as important for car manufacturers to employ their economic, environmental and social resources wisely – and efficiently.
