Bowen says that agreement on new standards means that EV owners will be able to use vehicle to grid technology - effectively using their cars as batteries on wheels - by the end of the year.
The idea isn’t to use V2G just to store power for the building, but to act as storage for the entire grid. So instead of building large battery farms to store power, you use EVs are the batteries, which reduces infrastructure costs and can accelerate the transition.
Obviously you’d want to have other grid level energy storage too, and some incentive to get owners to allow their EVs to be such a storage device, but thats the idea.
Transferring energy into and out of an EV does result in non-negligible energy loss.
Having a dedicated, stationary battery is a much more space and resource efficient way to provide a grid buffer. Pb-Acid and Iron-air batteries are much better for the environment than Lithium, and much more stable. They are much heavier, but still lighter than a Lithium battery powered EV.

Batteries are heavy, even lithium batteries.

That makes sense, but those incentives better be good for you to be putting any wear and tear on my battery that has limited cycles.
