Wastewater analysis at Bolivian lithium deposit explores how to avoid past environmental mistakes

Envirotec Magazine

The concentrated lithium is eventually moved from the evaporation ponds to a nearby facility for processing into lithium carbonate the material that goes into rechargeable batteries. My group has worked all over the world in Africa, Europe, Vietnam, India and I dont think we ever measured that level of arsenic.

Understanding Natural Hydrogen and Its Global Energy Potential

Hydrogen Fuel News

White hydrogen offers a naturally occurring, carbon-free energy source waiting to be extracted, unlike green or gray hydrogen, which require energy-intensive production methods. This region could also support carbon-negative hydrogen production by combining hydrogen extraction with carbon sequestration.
