It's a really long article but the trunkated version is this...

anybody with a more sciencey background know how plausible something like this is?

...It promises to nudge the world to a paradigm shift as big as the switch from centralized mainframe computers in the 1980s to personal laptops. But this time the mainframe is America's antiquated electrical grid; and the switch is to personal power stations in millions of individual homes....Inside Ceramatec's wonder battery is a chunk of solid sodium metal mated to a sulphur compound by an extraordinary, paper-thin ceramic membrane. The membrane conducts ions -- electrically charged particles -- back and forth to generate a current. The company calculates that the battery will cram 20 to 40 kilowatt hours of energy into a package about the size of a refrigerator, and operate below 90 degrees C.
This may not startle you, but it should. It's amazing. The most energy-dense batteries available today are huge bottles of super-hot molten sodium, swirling around at 600 degrees or so. At that temperature the material is highly conductive of electricity but it's both toxic and corrosive. You wouldn't want your kids around one of these.....
Ceramatec says its new generation of battery would deliver a continuous flow of 5 kilowatts of electricity over four hours, with 3,650 daily discharge/recharge cycles over 10 years. With the batteries expected to sell in the neighborhood of $2,000, that translates to less than 3 cents per kilowatt hour over the battery's life. Conventional power from the grid typically costs in the neighborhood of 8 cents per kilowatt hour.
Re-read that last paragraph and let the information really sink in. Five kilowatts over four hours -- how much is that? Imagine your trash compactor, food processor, vacuum cleaner, stereo, sewing machine, one surface unit of an electric range and thirty-three 60-watt light bulbs all running nonstop for four hours each day before the house battery runs out. That's a pretty exciting place to live....
And then you recharge. With a projected 3,650 discharge/recharge cycles -- one per day for a decade -- you leave the next-best battery in the dust. Deep-cycling lead/acid batteries like the ones used in RVs are only good for a few hundred cycles, so they're kaput in a year or so.
How do you recharge? By tapping your solar panels or windmills. It's just like plugging in your cell phone or iPod, only you plug in your house.
A small three-bedroom home in Provo might average, say, 18 kWh of electric consumption per day in the summer -- that's 1,000 watts for 18 hours. A much larger home, say five bedrooms in the Grandview area, might average 80 kWh, according to Provo Power.;Either way, a supplement of 20 to 40 kWh per day is substantial. If you could produce that much power in a day -- for example through solar cells on the roof -- your power bills would plummet.
Ceramatec's battery breakthrough now makes that possible...."Batteries and PV are about to merge," said MIT's Nocera, using the shorthand for "photovoltaics" or solar power. "First Solar is now saying that it takes $1 a peak watt to manufacture, and another 80 cents for installation. So they're saying that you can get PV for under $2 a watt. That's a reduction of cost by a factor of four. Only a few years ago, it was $8. If CoorsTek and Ceramatec come up with a good battery, the market will develop quickly."
"There are two classes of ceramic materials that are good conductors," Coors explained. "One is what developed here in the early days -- beta-alumina solid electrolyte, or BASE. It's temperamental, brittle. A.J. thought of a better material. It's a better conductor, easier to manipulate and process, and lower cost."
This is where the earth moves for renewable energy. The new electrolyte enables the development of an energy-dense, inexpensive and safe storage battery for use at home. Combined with the rapidly emerging thin-film solar cells, it presents an unparalleled business opportunity....
They're about about six months away from initial scale-up toward a commercial product, he said.
Lots of sodium will be needed to make the new batteries, and Ceramatec proposes a symbiotic relationship with the federal government to get it. Enormous quantities of sodium metals, the byproducts of nuclear weapons manufacturing, just happen be available for cleanup at Hanford nuclear reservation near Richland, Wash. It's a ready-made source of material that CoorsTek can recycle....
Take Deer Creek at the head of Provo Canyon, for instance. Generators at the dam can produce up to 5 megawatts, but they run mainly in the irrigation season. But water to sustain the Provo River has to be released all the time, and local residences, with batteries trickle-charging continuously, could benefit.
It's another value proposition added to others, like the net metering enjoyed by the Shepherds in Alpine. The idea in all this is to ease pressure on the grid while moving people toward greater energy independence.
"What we're talking about is the ability to take the edges off," Hunter said. "We're at a tipping point for alternative energy."
In Salt Lake City, Grover Coors agrees: "This will be the largest industry of all time," he said. "But it's all about cost and reliability.
