Big Renewable-Friendly Battery From Hitachi

Hitachi says it will begin demonstration tests in the North American market of a 1-megawatt lithium-ion container-style energy storage system.

Who knows how economical it might be, but the Japanese electronics and industrial giant Hitachi is moving toward marketing an energy storage system that could be a companion piece to renewable power generation — another sign of the growing interest in such products.

The company said a system called CrystEna (that’s “crystal” and “energy” shortened and squished together; maybe it sounds better in Japanese) will use lithium-ion battery technology in a 1-megawatt container-like package. At that size, this isn’t for home storage — nor is it the sort of storage that SolarCity has begun promoting for large business solar systems to cut peak demand.

Instead, this looks like a utility-scale application, the kind of thing that would be used in a fashion similar to the 4-megawatt sodium-sulfur battery system from NGK Insulators that the Northern California utility Pacific Gas & Electric is testing in San Jose.

But while Hitachi was announcing CrystEna, it was a bit unclear about exactly when and how it might come to market:
