successfull?, maybe, we will see if fires, insurance, and end of life disposal costs leave any roe, plus there are no large scale used car battery grid storage plants, just green washing for data centers, where they are most definitly worried about fires, given the huge spacing between units,
green washing/cred,scamenomics,, but most certainly, not grid scale
The Deutsche Bahn (german train system) also does that across its own grid.
Batteries from EVs charging and discharging in stable environments are a lot saver (and they are save anyway) and do not degrade anymore.
Why would that even be green washing? Where is this coming from? Those batteries are doing exactly what they should do and saved already co2 in their first lifetime.
And what has this to do with data centers? All of these battery grid systems have veen started before the AI boom.
