December 3, 2013 – Hitachi Ltd. says it 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 (e.g. wind, solar) while maintaining the power supply-demand balance.

This 1MW energy storage system—to be named CrystEna—fuses Hitachi’s electricity grid control technologies built up in the Hitachi Group and Hitachi Chemical Co. Ltd.’s battery-related expertise. Hitachi plans to begin a demonstration of this system in North America in 2014. 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. The company will also examine whether to promote the system as one of its solution businesses for expanding the transmission & distribution business in the global market.
