Any comment on the actual idea, which is being trialled in th UK?
It's actually a great idea and here's why.
Domestic vehicles spend some 90% or more of their life parked. So the opportunity for part of the nation's car fleet to participate in this at any one time is easily there.
We sell around 1 million cars a year in Australia so the build up of the asset could be quite large after a few years.
It is expected that evs with be price comparable dollar for dollar with ICE cars somewhere between 2010 and 2025. That means that the average person will buy an ev rather than an ICE powered vehicle because it will be cheaper when you take into account maintenance and running costs.
A Tesla powerwall ( typical home battery ) is about 10KWH. A Tesla S model car battery is a minimum of 85kwh. Even the smaller evs have batterys in the 50KWH range.
So, the car battery storage dwarfs the home storage in capacity. Given there are so many cars sold each year, it won't be too long before the ev battery fleet will be much much larger than the home storage network.
A very large CFPS is around 3000 mw. That is the equivalent of 30,000 Tesla S models with 100kwh batteries.
Of course you wouldn't use all of the battery so let's say you need access to 30% of the battery leaving 70% for the owner's use which is probably 250km or more. " An average Australian trip per day is under 50km so range isn't an issue .
That would mean you need 100,000 Tesla S models for the equivalent of a Loy Yang complex. About 10% of all car sales in one year.
Obviously 100,000 Teslas can't give you 3000mw for days like Loy Yang can but they can give you short term large amounts of power to manage morning and evening peaks easily. They can catch a cfps tripping so that the grid wouldn't even notice. They could help smooth the output from windfarms and solar panels.
Consider how well the Tesla stationary battery in SA is doing and then think of something that is 30 times it's size that is simply parked in driveways around the country.
No more gas fired peaking plants. CFPS wouldn't have to worry about load swings so they could be more efficient.
It's a no brainer imo.
