13. Liquid battery big enough for the electric grid?
Since this one is old, here's a clip from one from just two days ago (11/19/09)

Liquid battery big enough for the electric grid?

Theres one major drawback to most proposed renewable-energy sources: their variability. The sun doesnt shine at night, the wind doesnt always blow, and tides, waves and currents fluctuate. Thats why many researchers have been pursuing ways of storing the power generated by these sources so that it can be used when its needed.

So far, those solutions have tended to be too expensive, limited to only certain areas, or difficult to scale up sufficiently to meet the demands. Many researchers are struggling to overcome these limitations, but MIT professor Donald Sadoway has come up with an innovative approach that has garnered significant interest and some major funding.

The idea is to build an entirely new kind of battery, whose key components would be kept at high temperature so that they would stay entirely in liquid form. The experimental devices currently being tested in Sadoways lab work in a way thats never been attempted in batteries before.

...

Most battery research, Sadoway says, has been aimed at improving storage for portable or mobile systems such as cellphones, computers and cars. The requirements for such systems, including very low weight and high safety, are very different from the needs of a grid-scale, fixed-location battery system. What I did was completely ignore the conventional technology used for portable power, he says. The different set of requirements for stationary systems opens up a whole new range of possibilities.
