Hitachi to introduce 1 MW storage system

Japanese electronics giant Hitachi on Monday announced the development of a 1 MW lithium-ion battery storage system that it says will ensure the stable use of distributed renewable energy, such as solar and wind power, while maintaining the power supply-demand balance.

The company said the all-in one, container-type energy storage system fuses Hitachi Group’s electricity grid control technologies and battery technology developed by the Hitachi Chemical Co., Ltd. division as a packaged system.

Hitachi plans to begin testing the system in North America early next year. The company said it would introduce the system to the electricity trading market, or the so-called ancillary market centered on maintaining the electricity supply-demand balance after verifying its commercial viability and performance.

The company will also examine whether to promote the system, to be named CrystEna (Crystal+Energy) as one of its solution businesses aimed at expanding the transmission and distribution business in the global market.

Currently, solar, wind and other forms of distributed renewable energy are attracting attention around the world as a way to reduce CO2 emissions. Demand for energy storage systems is expected to grow rapidly because they can help maintain the electricity supply-demand balance, effectively utilize energy and stabilize power quality.

The European and North American markets, which are leading the way in electricity deregulation, are experiencing an increase in the use of distributed renewable energy, construction of transmission networks to transmit power generated from renewable energies to major cities and by renewable energy subsidies such as tax credit and feed-in tariff (FIT) schemes, the company said.

"The necessity for energy storage systems is thus rising for maintaining the supply-demand balance, power frequencies and voltages, securing backup power, and eliminating the impact on grid operations," it added.
