In order to compliment the growing use of renewable energies in the United States, additional technologies must be employed on the bulk power system. This paper forecasts the most probable energy storage technologies. These include: compressed air energy storage, pumped hydro, flywheels, lead acid batteries, and advanced battery technologies. A SWOT analysis was performed on each of the storage types to identify potential benefits or disadvantages. This analysis provided a multi-perspective view of these energy storage approaches. Next Bibliometric and Patent searches were conducted for all of the key technology types. This data was then used to create growth curves applying the Gompertz and Pearl methods. An analysis of this research shows the how different rates of growth correspond to the maturity of the various storage types, and predicts when some of the newer technologies will overtake the mature technologies in this area.
