Japan launches small container-type power storage system

Hitachi Ltd. has recently developed a small container-type power storage system, a 1 MW lithium-ion battery system package. An empirical test will be conducted in North America from the beginning of 2014. After verifying the effectiveness of the system in the power trading market related to maintaining the balance of power supply and demand, the results will be reflected in commercial products. Hitachi positions it as a core product for stabilizing energy storage systems that utilize distributed renewable energy such as wind power and solar power.


The 1 MW Lithium-Ion Power Storage System Kit integrates Hitachi's power system control technology with the battery-related experience of Hitachi Chemical Co., Ltd., which is part of the Group's advanced components business, and is housed in containers. Using Hitachi Chemical's lithium-ion battery, Extend battery life, improve performance, and use a compact design to achieve high economic efficiency.In an empirical test, the battery capacity will be verified for its optimality and durability.

Empirical tests conducted in North America target the rapidly emerging US auxiliary market. Auxiliary market refers to the establishment of a power trading market to provide services to maintain the balance of power supply and demand in order to adjust the gap between the amount of electricity generated based on the assumptions and actual demand. Hitachi will also test and verify the control algorithms that maximize revenue from electricity sales and accumulate relevant experience.

At present, the world is advancing the adoption of renewable energy, especially in the European and American markets. The market demand for power storage systems that can ensure spare capacity and eliminate the impact of grid use is expected to increase. Hitachi combines the words "Crystal" and "Energy" to name "CrystEna" the "1 MW Lithium-Ion Power Storage System Package" as one of the solution businesses aimed at expanding the power distribution business. , sales in the global market.
