I ran across the video on YT. This says that 20% of Australians from Perth are using Solar Cells for home power. Also, you have a new battery technology using Bromine. I thought that was interesting considering that I keep seeing these reports on the forum that there are walking brownouts and blackouts in the southern part of Australia. Is the use of batteries really that prevalent for home power? The $5000 government rebate looks nice as well.

Will people be able to ever run the house from the battery in their electric car i wonder.
it is really a failure at the political level.

The company referred to is almost certainly http://redflow.com/

Yes it would be Redflow.
I have a contact who can hook me up with a director of this company (Simon Hackett of Shark tank fame)

Where is there a $5k rebate for battery systems?
I'd be seriously interested in seeing some more detail on their tech. The stuff on their web is nice, but kinda vague.
I never understood this "lets place a battery to every home" movement. You dont want to place batteries at home. Batteries are expensive, they need maintenance, they are a fire hazard, they wear out. The grid operator needs to place batteries. They need to smooth out the power fluctuations, and supply the grid with reliable power. That is what we are paying for.
If your country is not using net metering, there could be a financial point to place batteries. But it is wrong. They should be using net metering, and have battery stations. The reasoning, is fundamentally wrong.
It is a different story than placing solar panels. You have a roof, an empty space, the energy company does not have lots of empty space.
And it is not economical. Solar panels are a different story, since even microinverters would be the most optimal. For batteries, the electronics scales very well. In theory, you can create a 10KV battery pack, run it through some SiC transistors, inductors, transformers, and get any AC voltage. It scales well upwards in power, not so much downwards. It costs hundreds of millions of dollars to make a power plant, surely, the grid operator will eventually be able to afford reasonably sized battery banks.

For utility grade batteries it seems to me it would make sense to do this along HVDC lines. Could literally use lead acid batteries for that if you set the voltage to a proper float voltage (multiple of 2.25). Each cell would be about the size of a backyard swimming pool and there would be enough of them to be at the HVDC nominal voltage. They could run along the line in flat long buildings. The utility owns that property anyway and it needs to be cleared of trees, may as well build there. They would not be very tall buildings, just very long. The HVDC would then be set to the float voltage of that battery. For example if you go with a 675,000 volts, that would be 300,000 cells. Actually, 600,000, you want at least 2 strings for redundancy. Seems insane but seems to me this is the right way to go about battery storage. Not sure how much actual storage you'd get out of that though, but it would basically act as a big capacitor. Give a better grace period to startup more generating stations. Maybe buy minutes instead of seconds.

Maybe buy minutes instead of seconds.Actually, the way I imagine it is on a a smaller scale. In Belgium, we have a problem in some cases, when the sun is really shining.All the solar panels, are generating electricity, so the voltage at a feeder would increase, and when it would increase above the limit, your inverter is shutting down. This already happens, and the problem will happen more often, the more solar panels are installed.
So the way I see it, the battery storage needs to be in a shipping container. It has to be a completely autonomous unit. Then the grid operator, would install these at the required places. Also, in case of an emergency, these can be relocated to the required location. They can be connected together, multiples next to each other, on top of each other, and so on. Complete, with built in fire suppressant system, space for maintenance, inverters, and so on, electro magnetically shielded, since it is a container, made out of steel. Lifetime of 10-15 years, we are supposed to have better battery technology by then anyway.
On the grid scale, probably, it makes more sense to use fuel cells. Or batteries, where the electrolyte is stored externally. Storing liquid in high quantity is solved, and probably a lot cheaper than making mega batteries, or millions of 18650 cells.
I plan on powering my home off AA alkaline cells. Sure you have to change the battieries but they are cheaper then rechargeable batteries and come fully charged. That will save alot in electricity when I have charge the batteries the first time I take them out of the box. Or even better idea: buy those dollar store "Heavy Duty" batteries. Im going with AA because the batteroo fits on them. Maybe augment them with some solar panels I can install under the parked cars in the drive way.
I can't wait for the first video of a refrigerator sized liPo battery exploding.
Photonicinduction on youtube has a good video on how he installed a bunch of batteries in his basement and recharges them at night with off peak electricity.
