Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode.

PNNL process extracts magnesium salt from seawater using laminar coflow

Green Car Congress

Researchers from Pacific Northwest National Laboratory (PNNL) and the University of Washington (UW) have developed a simple way to isolate a pure magnesium salt, a feedstock for magnesium metal, from seawater. The selectivity of this process makes it particularly powerful. —Wang et al. Qingpu Wang, Elias Nakouzi, Elisabeth A.

SiGNa Chemistry Demonstrates Sodium Silicate-Based Hydrogen Generation System for Portable Fuel Cells

Green Car Congress

Prototype sodium silicate hydrogen generation system as presented earlier this year at DOE merit review. The H300 utilizes real-time swappable cartridges that generate hydrogen on demand using SiGNa’s proprietary sodium silicide (NaSi) powder. Sodium-Silica-Gel: 2Na-SG + H 2 O → H 2 + Na 2 Si 2 O 5.

Researchers develop all-weather solar cell that generates power from rain as well as from sun

Green Car Congress

While many technical advances have made solar cells more efficient and affordable, a disadvantage remains in the fact that solar cells produce no power when it’s raining. This phenomenon inspired researchers working with Qunwei Tang to use graphene electrodes to obtain power from the impact of raindrops. mV and 7.17 pW for 9.46
