alt Hacker NewsI don't think that would ever commonly be viable or at least not for a long time. EV's are a lot more than batteries and are proportionally stupidly expensive. If the electricity net arbitrage was worth the degradation of the battery then .... companies would do it themselves and just build the batteries for cheaper at scale.

The battery is already a sunk cost. Doesn't matter how expensive the battery was if it's already sitting on your drive.
I did a quick fag packet calculation and even today 10% of everyones EV battery would be enough to cover the grid for an hour. That's enough of a buffer to spin up gas turbines for example, so you can actually shut them completely off.
It is commercially viable. A UK energy company already has a Vehicle to Grid tariff.
