Batteries Too Costly for Grid Energy Storage: Analysts

Despite all the attention on battery technology for energy storage for the power grid in the latest round of smart grid stimulus funds, current battery technology is just too expensive to be mass deployed right now, according to analysts at Black and Veatch. “Unless battery technology makes dramatic advances soon, B&V doesn’t see them being much of a factor in helping states like California meet their RPS goals looking out to 2020,” the firm told us in an email. Here’s a handy-dandy chart showing just how much cheaper compressed air energy storage (CAES) technology, flywheels, and pumped hydro are (further descriptions of these technologies here) compared to battery technology (NAS stands for a sodium sulfur battery, which are some of the cheaper forms of batteries already in use for the power grid):
