Hitachi makes shipping container size 1 MW battery for grid energy storage

Hitachi has developed an all-in one, container-type energy storage system as a core energy product for ensuring the stable use of distributed renewable energy such as wind and solar power, while maintaining the power supply-demand balance. This energy storage system fuses Hitachi’s electricity grid control technologies built up in the Hitachi Group and Hitachi Chemical Co., Ltd.’s battery-related expertise and will be offered as a packaged system.

In the beginning of 2014, Hitachi plans to begin a demonstration test of this energy storage system in North America. Plans call for Hitachi to reflect the results of this testing in a commercial product after verifying the commercial viability and performance of the system in the electricity trading market, or the so-called ancillary market*2 connected with maintaining the electricity supply-demand balance. Furthermore, Hitachi will examine whether to promote the system, to be named “CrystEna” (Crystal+Energy), as one of its solution businesses for expanding the transmission and distribution business in the global market.
