Breakthrough on salt-tolerant wheat

Green Car Congress

This work is significant as salinity already affects over 20% of the world's agricultural soils, and salinity poses an increasing threat to food production due to climate change. The salt-tolerant gene (known as TmHKT1;5-A) works by excluding sodium from the leaves. Richard James and University of Adelaide student Bo Xu.

UMD-led study: road salts and other human sources are threatening world’s freshwater supplies

Green Car Congress

Kaushal and his team named these cascading effects of introduced salts Freshwater Salinization Syndrome, and it can poison drinking water and cause negative effects on human health, agriculture, infrastructure, wildlife and the stability of ecosystems. In the built environment, salts can degrade roadways and infrastructure.

CalSEED awards $4.2M to early-stage clean energy innovations

Green Car Congress

is creating a streamlined manufacturing process for silicon solar photovoltaic cells that requires only 10% of the silicon, half of the operating and equipment cost, and a quarter of the energy of incumbent technology, enabling sustainable solar manufacturing that will combat climate change by meeting global demand for solar.

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.

Startups Begin Geoengineering the Sea

Cars That Think

The companys plan is to electrochemically strip carbon dioxide out of the ocean, store or use the CO 2 , and then return the water to the sea, where it will naturally absorb more CO 2 from the air. Thats a huge amount of water. The softened water passes through the electrodialysis unit, which applies a voltage.

ARPA-E awarding $39M to 16 projects to grow the domestic critical minerals supply chain

Green Car Congress

First, an electric potential will be applied to water to simultaneously produce acidity and alkalinity. The technologies use electricity to extract valuable metal ions from the surrounding mineral matrix at sub-boiling temperatures. Feedstocks will include Li/Ni/Ca/Mg-rich igneous and sedimentary minerals. Idaho National Laboratory.

Sodium-ion batteries are set to spark a renewable energy revolution – and Australia must be ready – ET Auto

Baua Electric

Some types of lithium mining require a lot of water and energy and have led to local pollution, such as in South America’s alpine lakes. But a new way to firm up the world’s electricity grids is fast developing: sodium-ion batteries. Sodium-ion batteries are now almost ready to fill the long-term storage gap.
