New energy storage technology acts like a UPS for your entire house

Summary:Priced starting around $45,000 the device from Rosewater Energy is pitched as a complement to solar installations or for places where the grid electricity supply is unreliable.

Is it me, or do a lot of the energy storage technologies making their way onto the market look a lot like especially big UPS devices (aka uninterruptible power supplies)?

The latest one that I'm reading about comes from Rosewater Energy of Fort Lauderdale, Fla., which is launching something called the Rosewater Residential Energy Storage Hub.  

The company makes no bones about the UPS connection in its product description: the hub uses 10 kilowatt (kW)/12 kilowatt-hour (kWh) power quality technology to act as a surge productor and to act as an alternative power source in cases of an outage.

Rosewater's device uses lead-carbon (PbC) batteries from Axion Power, which it says outperform traditional lead-acid battery technologies.

It is being pitched as a complement to solar installations, helping store electricity when the sun is shining, and as method of helping homeowners participate in demand response programs -- where utility customers get credit for reducing demand on the grid.

Of course, that's provided you have the money to pay for it in the first place -- the technology is priced around $45,000. It should be interesting to see what financing models emerge to support its adoption. And, frankly, where to put it.
