I recently read an article about a company that develops technology for re-using worn-out EV batteries for grid storage. After all, your EV battery with 70% capacity would be useful for many years somewhere in the desert with thousands of other similar batteries, as large-scale grid storage. The technology was great, the business model was sound, grid operators were very interested, everything was fine, except… the supply of those EV batteries.

Turns out those EV batteries do not degrade as quickly as we were repeatedly told (by black PR, my guess) and there simply aren't enough to go around :-)

EDIT: I can't find the original article, but I found this: https://www.forbes.com/sites/carltonreid/2022/08/01/electric...
