New mesoporous crystalline Si exhibits increased rate of H2 production; potential use in Li-ion batteries also

Green Car Congress

The etching process uses to produce porous silicon results in the loss of material, said said Donghai Wang, assistant professor of mechanical engineering, who led the research. Instead, Wang’s team uses a chemically based method that builds up the material rather than removing it. Batteries Hydrogen Production Solar Solar fuels'

GE and PowerStream launch Ontario microgrid demonstration project; Durathon batteries

Green Car Congress

For the project, GE provided its Grid IQ Microgrid Control System (MCS), as well as the engineering design services, to help PowerStream build a microgrid, which uses renewable energy resources (wind, solar); a natural-gas generator; and energy storage devices (including GE’s Durathon sodium-metal halide batteries, earlier post ) to provide electricity (..)

Caltech engineers devise new thermochemical cycle for water splitting for H2; recyclable, non-toxic, non-corrosive and at lower temperatures

Green Car Congress

The research group led by Mark Davis, the Warren and Katharine Schlinger Professor of Chemical Engineering at Caltech, describes the new, four-reaction process in an open access paper in the Proceedings of the National Academy of Sciences (PNAS). °C that is completely recyclable and does not involve toxic or corrosive intermediates.

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.

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Short-term transients, including those related to wind and solar sources, present challenges to the electrical grid. To maximize the benefit of the open structure, the researchers needed to use ions that fit; hydrated potassium ions proved to be a much better fit compared with other hydrated ions such as sodium and lithium.

Debunking the Lithium "Mining" FUD

Plug In India

The interesting thing is before electric cars were popular, no one in the auto industry or mainstream media even questioned where petrol or the metals used in engines are coming from. Thier technical development unit has examined how the carbon footprint of electric cars in compares with that of internal combustion engines.
