Researchers develop new stable artificial photosynthesis device to produce ethylene and hydrogen from sunlight and CO2

Green Car Congress

Electron microscopy experiments at the Molecular Foundry confirmed that cuprous oxide quickly oxidizes or corrodes within minutes of exposure to light and water. We knew it was unstable—but we were surprised to learn just how unstable it really is. This work was supported by the DOE Office of Science. Zheng, F.,

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.

Molten carbonate electrolysis can produce a range of carbon nanomaterials, including graphene, from CO2 at high yield

Green Car Congress

The utilization of the full spectrum of sunlight in STEP results in a higher solar energy efficiency than other solar conversion processes. Electrochemical exfoliation of graphene is a process in which intercalated ions between graphite layers are oxidized, forming gases which break apart the interlayer bonds, and release graphene sheets.

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

Stuart Licht ( earlier post ) have developed a new process that transforms CO 2 into a controlled selection of nanotubes (CNTs) via molten electrolysis; they call the process C2CNT (CO2 into carbon nanotubes). The production of synthetic fuels from carbon dioxide (and/or water) has been widely studied and can be efficient.

China team engineers bacterium for photosynthetic production of ethanol from CO2

Green Car Congress

Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (China), applied a consolidated bioprocessing strategy to integrate photosynthetic biomass production and microbial conversion producing ethanol together into the photosynthetic bacterium, Synechocystis sp. coli to test ethanol-producing efficiency.

Tony Karrer Delicious EVdriven

There are companies that are reinventing the lead-acid battery to make it more competitive with lithium-ion and nickel metal hydride in terms of storage capacity versus weight, durability, and cold weather performance. In most conversions cost is about the same because of needless weight.
