Quoting from EcoGeek:

A company in Salt Lake City, Utah is developing a battery system for home-based electricity storage that may make energy storage much easier and more economical for off-the-grid homes as well as helping to improve the efficiency of grid-tied homes.

The technology being developed by Ceramatec is a new variation on sodium sulfur batteries, an existing technology with very high energy density, but best suited for very large scale, industrial style installations such as grid storage. However, these batteries have the potential to bring the advantages of sodium sulfur batteries to a much wider range of uses.

Currently, sodium sulfur batteries operate at very high temperatures - above 300 degrees C (572 degrees F), and the components in them are corrosive. This isn't the sort of thing that you would want in your home, and, for efficiency, they work best at a much larger size they aren't really at a home-scale size. On the other hand, there are some advantages to sodium sulfur batteries. They use very common and inexpensive materials, which makes them attractive. And the high energy density means that a small battery is all that is needed for a large amount of energy storage.

The Ceramatec battery separates the sulfur and sodium from each other with a thin ceramic membrane which allows electricity to be stored while operating at a much lower temperature. Ceramatec envisions a refrigerator-sized unit that would remain below 98 degrees C (208 degrees F), the melting point of sodium. Keeping the sodium solid makes for a much safer battery. The battery could store 20 kWh worth of energy, either from local, sustainable sources such as wind or solar, or from off-peak recharging from the grid, much like a plug-in hybrid car recharges when the grid demand is low.

: "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." (Daily Herald)
