Progress! Does that density mean smaller batteries as one might
think? With extraction and desalination at the Salton Sea
California might be energy independent.
Batteries aren't an energy source
Yes, I misspoke: the "independence" would be from better storage of
energy sources. The implication in the article was that a lithium
battery could have the same energy as the same sized gas tank.
it's really hard to imagine what a doubling of battery use in our transportation energy system would do. A set of batteries in the car.
A set of batteries in the grid to store it so it's available to
charge our car batteries at night.
That would do.
Salton sea has some mountains nearby. I'd be more inclined to look
for a hydroelectric storage solution or even a hydrogen system
It's full of lithium and has geothermal resources.

"Recent legislation mandates that all of the state’s electrical power
come from renewable sources by 2045. Besides lithium, our new report
discusses using electrolytic hydrogen and pumped water as methods for
storing electrical power, which could help the state meet its goals.
Hydrogen gas produced by electrolysis of water, using electricity
supplied by geothermal energy, can be stored or transported to provide electrical power. Pumped water can also be stored in raised reservoirs
and released to generate hydroelectric power during peak demand hours."
that lasts over doubling the battery demand which still need
frequent replacement. Since the source is limitless and free
(solar), efficiency at that point of the system isn't that great a
concern. Consider solar panels are 25% at best.
I also assume it could be years before a practical application but
those present three thousand pound batteries aren't ideal.
Of course new battery tech on the horizon always makes current e-car
buyers a bit foolish as their car becomes relatively worthless.
One could argue buying any new car is foolish given the instant
depreciation. I buy used and drive them forever.
