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.

UH team reports new catalyst efficiently produces hydrogen from seawater; promising for large-scale hydrogen production, desalination

Green Car Congress

Researchers say the device, composed of inexpensive non-noble metal nitrides, manages to avoid many of the obstacles that have limited earlier attempts to inexpensively produce hydrogen or safe drinking water from seawater. The researchers tested the catalysts with seawater drawn from Galveston Bay off the Texas coast.

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.

CU-Boulder technique finds major class of fracking chemicals no more toxic than common household substances; “fingerprinting”

Green Car Congress

EO28), were identified in hydraulic fracturing flowback and produced water using a new application of the Kendrick mass defect and liquid chromatography/ quadrupole-time-of-flight mass spectrometry. The Kendrick mass defect differentiates the proton, ammonium, and sodium adducts in both singly and doubly charged forms.
