Study finds high sodium bicarbonate concentrations in water from coal-bed natural gas production harms aquatic life; water treatment can mitigate effects

Green Car Congress

Produced water from coal-bed natural gas (CBNG) production may contain sodium bicarbonate (NaHCO 3 ) at concentrations that can harm aquatic life, according to a new study by the US Geological Survey; Montana Fish, Wildlife and Parks; the Bureau of Land Management and the US Environmental Protection Agency.

KAUST team devises electrically-driven membrane process for seawater lithium mining

Green Car Congress

Researchers at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia have developed a continuous electrically-driven membrane process which successfully enriches lithium from seawater samples of the Red Sea by 43,000 times (i.e., 13000 ppm of sodium, magnesium, calcium, and potassium ions, among others).

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 new method flows two solutions side-by-side in a long stream. —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.

TUAT team develops more efficient method to recover heavy oil using novel chemical flooding

Green Car Congress

By making use of a previously undesired side effect in oil recovery, researchers at Tokyo University of Agriculture and Technology (TUAT) have developed a method that yields up to 20% more heavy oil than traditional methods. To yield more oil, water may be injected into the reservoir to maintain pressure in order to keep the flow moving.
