One simple solution is utility scale battery storage in neighborhoods and at the distribution complexes. Already part of the SmartGrid model.

Another obvious solution is for utility companies to work with the smaller residential generator manufactures (Genrac, Eaton, Honeywell, etc) and produce a product that uses repurposed EV batteries, is controlled by the utility itself -- such that the unit can provide local multihouse storage, power factor correction, and demand reduction. Foot print of such boxes would be same as about a 10KW generator. And they could have the added side benefit of providing standby power when the storms hit.

Trying to use a car for EV2Grid is not going to fly! The automakers will never accept the liability for possible damage AND/OR cover the reduced life of the battery. Yes even Lithium Ion batteries have a charge/discharge cycle life. Plugging them in at night and using them to provide power back to the grid - is likely to reduce the useful life. FWIW EV batteries are considered near end-of-life when the have about 80% of their charging capacity left. But as a repurposed battery for small residential standby, powerfactor, voltage optimizing, demand reduction -- the same batteries could perhaps be used until their cycle life is down to 40%.

A permanently installed "EV battery Generator" controlled by the utility could be a win-win for the homeowner and utility. Utilities could command the storage box to charge -- whenever they can buy the power at the lowest rates. They can effectively sell it in the neighborhoods at a much higher rate -- without having to pay for the land the storage boxes sit on. Home owners can lease the boxes -- providing additional income to utilities - and in exchange the homeowner get a "standby generator".

So as Mike Trust suggested --- there is a product/marketing opportunity.
