​​​INL researchers are evaluating options including heavy vehicle battery packs, fly wheels, flow batteries and supercapacitors
Variability in electricity demand is a challenge for intermittent renewable sources, but large-scale storage systems ​could fill gaps in energy availability and reliability. The ideal combination of energy source and backup system depends on the electricity demands of each particular end user. Since usage and recharging patterns impact a storage system’s performance and lifetime, INL tests and demonstrates a variety of systems to understand which are best suited to a particular scenario.
