Eos Energy Storage develops 1 MW battery storage device

Eos Energy Storage announced partnerships this to deploy its battery energy storage technology with electric power utilities in the U.S. and Europe.

Eos’ Aurora energy storage system is a 1 MW zinc hybrid cathode battery the size of a washing machine that the company projects could supply power to the grid for around $160 per KWh, compared to between $400 and $1000 per KWh for current battery technologies, Eos executives told The New York Times.

“Eos is focused on producing a reliable 25-year battery that can integrate into the utility grid at a price equivalent to a combustion gas turbine,” said an official with the Public Service Co. of New Mexico, one of Eos’ partners in the venture. “If they can do that, Eos will be in a position to change the way utilities do business.”

Eos’ partners in its “Genesis program,” to deploy early iterations of its technology in 2014, include utilities representing more than 300 GW of power generation and 76 million customers in 70 countries, according to a press release.

According to Power Engineering, the partners say the program represents a major step in bringing viable energy storage to the grid, which could radically change not only systems for meeting peak demand, but the economics of intermittent renewable technologies as well.
