According to the analysis, bringing lithium-ion batteries online for grid storage would be a good way to stockpile energy for when it’s needed, and it would prove less costly than building and operating new natural-gas plants.
The finding comes at an interesting time. For one thing, the price of lithium-ion batteries continues to plummet, something that certainly has the auto industry’s attention. And grid-scale batteries, while still relatively rare, are popping up more and more these days. The Minnesota report, then, suggests that such projects may become increasingly common—and could be a powerful way to lower emissions without sending our power bills skyrocketing in the process.
