We’ve burned fossil fuels.
For a while.
Now, after figuring out that the whole planet is about to become to hot for comfort, we’re slowly replacing fossil fuel with ‘renewable power’. Solar and wind…
And we’re looking for ways to store that power for when the sun is powering the other side of the planet and the wind has stopped blowing.

Lithium to the rescue!
Lithium batteries are the new fad. Powerful enough for Tesla to build around them the ‘coolest’ car ever. Accelerates faster than a Ferrari at less than half the price.

But is this really wise?

Lithium – like oil, has to be dug up from somewhere. Hence it’s not ‘renewable’. Only recyclable, but at a hefty price.
Lithium – like oil, is really messy. To produce in the first place and to recycle.
Lithium – like oil, can be found rather far away from where its needed. Hence has to be transported over large distances. And happens to be under ‘foreign’ control. Much of it, anyway.

So how much farther are we going to go?
On the already ‘paved’ road?
On the other hand, I’m sure Nansen had something else in mind. Other than repeating the same mistake.

An alternative method for storing power would be to use daytime solar and ‘excess’ wind power to produce hydrogen. Which can be stored where it is produced and will be used. Or ‘loaded’ unto fuel cell powered cars.
