  1. There is a huge private school near me. Out back they have a line up of at least 25 school buses which are all diesel. They sit in those spots 20 hours a day and only go out to pick kids up and then take them home at the end of a day. Diesel powered vehicles are completely unsuited for this type of stop and go city driving. They have horrible efficiency and massive carbon footprints for operation. And they emit all that other junk near kids in dense urban areas. Instead you replace the buses with BEVs that have 200 kWh batteries. That is 5000 kWh of potential storage. You install a solar array on the massive roof of the building that is doing nothing and you charge them all while they are sitting there daily. You can then use V2G to power the building if needed or back to the grid to stabilise. Now do this for every bus and every school. And then do it for every private vehicle. There is a massive potential here and this future is likely coming quicker then most people think.

  2. Yes, it would help the grid to have cars act as decentralized storage… until people become conscious of the limited charging cycles their batteries have and the price to replace them. I wouldn’t be opposed to using the “EV grid” exclusively during the peak hours of summer, but I fear the usage would creep.

    Edit: Just get a powerwall for the house. By limited charge cycles, I’m talking about the limited number of times you can charge-discharge the cells. It’s cheaper to just build/buy a powerwall for this purpose. Plus you can use it when you’ve taken the car for a drive, or charge from solar when you’ve taken the car to the office.

  3. I think V2L is going to be one of the main selling points for these vehicles in the future. Even low range EVs have as much power on board as 4 power walls. Why pay for a powerwall/generator if your car can do both?

  4. Great idea in theory, in practice I see difficulties

    I love the idea of distributed generation and storage. I don’t like the idea of someone else remotely controlling my stuff

  5. Now that there is security in energy grid, we may see advanced efforts in alternative energy. Only because big electric industry is not threatened by green energy no more. Now let’s find best way to power grid.

  6. The last time this came up,I had an interesting conversation with someone who was doing planning for this. He said it was a massive headache from a control and distribution standpoint and not worth it. Not my words.

    I’ve had some time to think about this and I still believe (because I’m not an expert) that such problems can be ironed out, especially with a very large number of vehicles involved.

    The article glosses over how utilities will deal with constantly changing battery capacity, configuration and even location and that’s a real challenge that must be taken seriously.

  7. After having just had a 15 hour black out during a record high heat wave, I still can honestly say I wouldn’t use my EV as a back up. Cuz at some point I will need a car. What if was an emergency that I needed to be somewhere, and I was without power for more than a day or two? Unless I have an ICE vehicle also, I’d never want to be without my main transportation

    I’d rather use a generator for emergency backs ups.

  8. Electric monopolies are paid cost plus a percentage return on capital investment. They are not paid to be efficient or for your capital investment in a vehicle with V2G capability. Until this aspect of Americas utility system changes V2G will not be significant in America. The problem is utility profit beats the public good not is there an efficient technical way to solve our grid issues.
