Stanford team develops efficient electrochemical cells for CO2 conversion

Green Car Congress

The electrochemical cells created by Kanan and his team combat these inefficiencies with a modified design that produces a concentrated stream of ethylene gas and a sodium acetate solution 1,000 times more concentrated than product obtained with previous cells. The cell uses a gas diffusion electrode (GDE) combined with a carefully designed flow field that greatly improves the delivery of CO to the electrode surface and the removal of products.

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. STEP is an efficient solar chemical process, based on a synergy of solar thermal and endothermic electrolyses, designed to convert greenhouse gas carbon dioxide into a useful carbon commodity.

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

Green Car Congress

The technique uses a solvent such as sodium or potassium hydroxides, converted by reacting with CO 2 to aqueous carbonates or bicarbonates. BPMED then regenerates the CO 2 gas. The high-pressure acid stream is transferred to a gas evolution/separation tank where the pressure is reduced with concomitant release of pure CO 2. Schematic of the HP-BPMED device used in the renewable fuels research. (a)

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

Sandia National Laboratories (SNL) researchers are progressing to the demonstration phase of a supercritical CO 2 (S-CO 2 ) Brayton-cycle turbine system for power generation, with the promise that thermal-to-electric conversion efficiency will be increased as much as 50% for nuclear power stations equipped with steam turbines, or 40% for simple gas turbines. This configuration uses gas-foil bearings and includes a small turbine (red).

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. However, while issues such as fleet consumption and CO2 emissions have been firmly put on the public agenda, the equally considerable environmental impact of the production phase of car manufacturing has as yet been largely ignored.
