The American electricity grid is remarkable and unique.  It forms one Read more [...]

As more and more grid energy storage projects are planned, how do you select the best technology for the need, or even begin to report and compare performance?  Comparing pumped hydro, compressed air, sodium sulfur batteries, flow batteries, lead acid batteries, lithium ion batteries, flywheels, and capacitors is akin to comparing apples to oranges to pears to kumquats to….you get the point. Ambiguity in measuring performance in energy storage could result in slowing down adoption of Read more [...]
