To the extent that the following claims are true, V2H makes a lot of sense: - The battery in your vehicle is way bigger than you actually need for expected and surprise daily uses. You have at least a few hours warning before trips >150mi or are comfortable needing to fast-charge. - The lifetime of your vehicle's battery is longer than the lifetime of other components. This can be because of the afformentioned way-too-big battery, because intelligent charging avoids the 80-100% range, or due to new chemistries like LiFePO4 - The variation between min and max electricity price is substantially higher than battery inefficiency. These factors seem mostly false for the first generation of electric vehicles (Leafs, etc.) but much more true for newer EVs with giant batteries. People seem pretty comfortable having a petrol car in their garage with less than 150mi of gas, so it's not surprising they'd be willing to do the same with an EV.
