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. The conversion process builds upon the solar thermal electro-chemical process (STEP) introduced by GWU Professor Stuart Licht and his colleagues in 2009. times above that of sodium-ion batteries with graphite electrodes.

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

Green Car Congress

Dr. Scott Elrod, VP and Director of PARC’s Hardware Systems Laboratory (HSL) research organization also directs the Cleantech Innovation Program at PARC, which develops solutions for delivering affordable solar energy, increasing solar cell efficiency, purifying water, managing energy utilization, and producing renewable fuels. The first application of this technique has been for silver gridlines on the front surface of solar cells. BPMED then regenerates the CO 2 gas.

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).

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. Photovoltaic Solar Energy. Solar photovoltaic (PV) devices harvest and convert sunlight directly to electricity. Advanced systems such as lithium-air, sodium-ion, as well as lithium-ion with new cathode chemistries are appropriate.
