PG&E Unveils Battery Storage System In San Jose, California

This looks interesting.  I have no idea if it's promising.  But...large amounts of elemental sodium.  Yikes!!

It and the California Energy Commission just yesterday “unveiled an innovative battery energy storage system pilot project.” There are no details on the cost (just a note that $3.3 million came from the Energy Commission), but the press release does note that it is a “utility-scale sodium-sulfur battery energy storage project” and that it has a capacity of 4 megawatts, with the ability to store more than six hours of energy.
As usual, it will come down to how much room these things take up, how expensive they are and how much of the cost the consumers will have to pay for this.
