Choices For Mining Lithium

The Salton Sea is one of numerous new mining proposals in a global gold rush to find new sources of metals and minerals needed for electric cars and renewable energy.

Thanks to the New York Times for this coverage of the choices surrounding how and where to mine a key ingredient of more efficient batteries–a consequential environmental question:

The Lithium Gold Rush: Inside the Race to Power Electric Vehicles

A race is on to produce lithium in the United States, but competing projects are taking very different approaches to extracting the vital raw material. Some might not be very green.

“This is the most sustainable lithium in the world, made in America,” Rod Colwell, the chief executive of Controlled Thermal Resources, said. “Who would have thought it? We’ve got this massive opportunity.”

Atop a long-dormant volcano in northern Nevada, workers are preparing to start blasting and digging out a giant pit that will serve as the first new large-scale lithium mine in the United States in more than a decade — a new domestic supply of an essential ingredient in electric car batteries and renewable energy.

The mine, constructed on leased federal lands, could help address the near total reliance by the United States on foreign sources of lithium.

But the project, known as Lithium Americas, has drawn protests from members of a Native American tribe, ranchers and environmental groups because it is expected to use billions of gallons of precious ground water, potentially contaminating some of it for 300 years, while leaving behind a giant mound of waste.

Turning Point In USA’s Transition To Electric Vehicles

General Motors has partnered with EVgo to deploy more than 2,700 fast chargers across the U.S. CREDIT: GM

John Paul MacDuffie and Sarah E. Light, both professors at the Wharton School of Business at the University of Pennsylvania, have published an article on Yale E360 highlighting the improving potential for electric vehicles to dominate the USA market sooner than previously expected:

EV Turning Point: Momentum Builds for U.S. Electric Vehicle Transition

Driven by GM, Tesla, and the Biden administration, the U.S. is now poised to press ahead in the transformation to electric vehicles. Big challenges still loom, but technological advances, government support, and growing consumer appeal will drive the inevitable switch to EVs.

Last month’s failure of the Texas electric grid, coming just weeks after General Motors’ pledge to make only electric vehicles by 2035, highlights the daunting task the United States faces as it takes the first steps toward weaning its economy off fossil fuels. Continue reading
