Electric vehicles are often called batteries on wheels, and indeed the amount of energy stored in a typical EV could run a home for days. Such is the promise of EV power storage, there are hopes the mass adoption of the technology can be used to help prop up the grid and boost Australia’s energy transition. But some are warning vehicle-to-grid technology could be more rhetoric than reality.

00:00Richard Chapman is a very modern type of car man.
00:06He loves cars, but he's also obsessed with all things tech.
00:10Oh, it's epic. Yeah, it's so good.
00:13It's one of the reasons he was such an early adopter of electric vehicles, or EVs.
00:17At his home in the Perth suburb of South Fremantle, he uses solar power to charge the car for a pittance.
00:23Ideally, he'd also like to use the energy stored in his car's battery to power his house when the sun goes down.
00:30When the main house batteries have run out, I want to then be able to draw off of the electric vehicles that I've got hundreds of kilowatt hours sitting there.
00:40But there's a catch. His car maker won't let him.
00:43Tesla are very reluctant to have you do that, at least on the cars that they currently sell in Australia.
00:48At issue is a little known technology that some say has big potential.
00:52It's called a few things, including vehicle to grid and bi-directional charging.
00:56It involves not only charging EVs so they can be driven around, but discharging them as well to power appliances,
01:02help run a household, or even sell power to the grid.
01:05The big golden pot at the end of the rainbow of vehicle to grid is that if we have a couple of million cars
01:12that are able to export to the grid at peak time, will mean that we can do things like close down coal-fired power stations.
01:19We're in the cheap power 9am to 3pm window.
01:23The Federal Government backs the technology and is calling on car makers to get on board.
01:27While I certainly encourage car manufacturers to get with the program, consumers will want this
01:31and I think consumers will march with their feet.
01:33Australia's uptake of EVs is still relatively subdued.
01:36About one in ten new car sales is electric, but that's expected to grow markedly in the years ahead,
01:42providing what experts say is a massive opportunity for the electricity system.
01:47From there we need the homeowner to be rewarded for vehicle to grid.
01:51They're not going to support the grid just because it's a nice thing to do.
01:55EV owner Richard Chapman, for one, is raring to go.
01:59We've got all this battery storage around all in our suburbs and what we need to do is tap into that
02:04because we've got all of this solar.
02:06An EV revolution at risk of being stalled.
