The U.S. is looking for new battery technologies that are cheaper and can hold onto power longer.
The U.S. Energy Department plans to offer a total of as much as $30 million to researchers developing stationary energy storage systems that can deliver power to the grid for as long as 100 hours, according to a statement Tuesday. The Advanced Research Projects Agency-Energy will administer the program, which is open to a broad range of technologies including mechanical systems like giant flywheels, and new chemical or electrochemical concepts such as flow batteries.
