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. times above that of sodium-ion batteries with graphite electrodes.

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Here, we describe for the first time the design of a reversible hydrogen storage cycle based on the redox system bicarbonate/formate. Most importantly, after full conversion of the formate, the bicarbonate solution may be recharged with hydrogen to close the cycle. Unfortunately, this has not yet been achieved. at 20 °C in H 2 O).

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

Turbo-alternator-shaft design for the SNL S-CO 2 test loop. The key component of these loops is the turbo-alternator-compressor unit (TAC) and the technologies used in its design. Because of the extremely high power densities and fluid density, Sandia has filed a Technical Advance for the TAC design. Source: Wright et al.
