There never was any follow up to the press release above.
The research article that came out of it was probably this one.Assessing the stationary energy storage equivalency of vehicle-to-grid charging battery electric vehicles
The main conclusion I get from this
Vehicle-to-grid-based energy storage has less overall flexibility compared to stationary energy storage.
It is better to buy a Powerwall as battery backup than try to use your car.
There's an interesting talk about the battery survey results collected by Plugin America. here - https://www.youtube.com/watch?v=WLUUfmRkRcA
His talk is very cautious and careful not to dramatise the results. You only get a sense of possible negative data in the Q and A at the end.
I think the most interesting part of the talk is his analysis of the cost of battery deterioration per kWh throughput. He suggests a cost of 40 cents for each kWh cycled through the battery. He uses this to inform the economic reality of using V2G.
For our Soul EVs, if hypothetically a replacement battery costs $6,000USD and lasts only 1000 cycles (160,000km) then the cost of battery deterioration per kWh throughput is about 45 cents.
