Battery backup for wind?

One of the central problems in relying on wind as an energy source is that wind is not entirely reliable on a 24/7 basis. One solution would be to store some of the energy produced by wind and rely on the stored energy during times of low wind. Creating such a technology, with economics that make it viable, has proved to be challenging.

One such attempt, a double-decker-sized sodium and sulfur battery is described in a recent article of Medill Reports of Northwestern University.
