Fraunhofer team develops process to recycle carbon black from car tires

Green Car Congress

Waste tires have been used mainly for recovering energy sources; only small proportions of the carbon black contained in these tires are recycled, since mineral ash accounts for around 20% of its content. Around three kilograms of carbon black—also known as industrial soot—are found in a standard car tire. © Fraunhofer IBP.

Chinese steel group Tsingshan investing $375M to build lithium plant in Argentina with Eramet

Green Car Congress

China’s Tsingshan , the world’s largest producer of stainless steel, will invest $375 million to build a lithium plant in Argentina with French multinational mining and metallurgy company Eramet. The project consists in extracting brine from the salar and processing it into lithium carbonate.

Researchers devise seawater-resilient bipolar membrane electrolyzer for turning seawater into hydrogen

Green Car Congress

The results of their study, published in Joule , could help advance efforts to produce low-carbon fuels. Generation of H 2 and O 2 from untreated water sources represents a promising alternative to ultrapure water required in contemporary proton exchange membrane-based electrolysis.

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. Earlier post.) —Licht et al.

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

Green Car Congress

The thermochemical production of hydrogen and oxygen from water via a series of chemical reactions is of interest because it directly converts thermal energy into stored chemical energy (hydrogen and oxygen), and thus can take advantage of excess heat given off by other processes. —Xu et al.
