I had hopes a really monster large vat (talking 1,000s of tons) of this stuff might have been cheaper.
Maybe, say, $10 / kWh.
In computer vernacular, longer term (archival) storage for some smaller EESUs with their very high power and energy flexibility (cache).
But, at $250 vs. $100 / kWh (***IF*** that is an apples to apples comparison), it's a no brainer.
EESU is, hands down, the better choice, on both power rate and energy capacity.
Even at a matching $250 / kWh, EESU is a better deal.
On power rate, alone.
Actually Donald Sadoway is aiming at 50$ per kWh!
He says "if you wish to make it dirt cheap, you need to practically make it from dirt".
His comments on cost are at about 6 min. into the following video, if you have the time watch the entire video, 20 min. plus.
This talk is about a year old and they have made progress since then.

This is the first large scale battery technology I expect to come to market at an advantageous price point, 14 acres of these (the size of a small shopping mall) will store 13 giga watts of electricity, enough to run New York city for 24 hours.
This starts us down the road to energy independence, however it still leaves control in the hands of the utilities.
For total independence, we will need an EEStor or something of similar capability.
When the facts change, I change my mind," John Maynard Keynes once observed in a debate. "What do you do, sir?" Why, sir, they take no notice of changed facts and so are untroubled by such questions.
