> Can "second life" EV batteries work as grid-scale energy storage? Yes is it profitable? probably not. Looking at the price for brid battery storage, and its dropping precipitously. The cost isn't as much in the batteries them selves, it packaging, placing and then controlling them. For example if you want to have a 200Mwhr 100Mw storage site, you'll need to place it, join it to the grid, all doable. Then you need the switch gear to make it work as you want it to. For day ahead, 30 minute trading, thats fairly simple. For grid stabilisation, thats a bit harder, you need to be able to lead/match/lag the grid frequency by n degrees instantaneously. which is trivial at a few kw, much harder at 100Mw

'probably not'? Based on what numbers? Germany alone had to pay 2 billion in dispatch measures to energy providers. And in the last 6 month we had news about a HUGE request of companies wanting to build grid stabilisation and grid market battery systems in a range of over 100GwH. Also we do have industries which would be able to save a ton of money if the invest in smaller but similiar systems today already due to energy prices. And in germany for example, we do have a lot of wind energy in the north but not enough live transit capacity to get it into the south. In this scenario the market would again stabilize the grid by charging at night from cheap / free wind energy production in north and transfering it to the south and then using it at day.
