With renewable energy potentially causing fluctuations in the nation's electric grid, Hitachi's energy storage system aims to offset this issue as well as meet growing energy demand for wind and solar.
Hitachi anticipates testing this energy storage system, to be named CrystEna (Crystal+Energy), in North America in 2014. It could be available for commercial purchase by the end of 2015, Tatsuro Ishizuka, president of Hitachi's power systems unit said. New regulations emerging in the U.S. are requiring companies and other organizations to look into incorporating renewable energy sources, and Hitachi's power systems could help them comply with these green energy rules.
"As the use of renewable energy expands, stabilization has become a very important priority," said Masaaki Nomoto, general manager for Hitachi's transmission and distribution systems, according to Bloomberg.
The firm projects the U.S. market for devices that will stabilize the grid will expand to 20 gigawatts by 2020, with potential for its energy storage system to contribute 7.5 GW to the market.
In October, the California Public Utilities Commission enacted the first energy storage mandate in the U.S. in a unanimous vote. Under the new mandate investor-owned utilities will be required to purchase at least 200 megawatts of energy storage by 2014 and 1,325 MW by 2020.
