Summary

Energy storage is a critical component of future energy systems where energy waste streams are exploited, energy efficiency is maximized, and fluctuating renewable energy inputs are managed. Many existing and emerging technologies exist to store different forms of energy at a variety of scales and over a variety of storage periods. Several technologies are described and compared. An overview of the role of storage with respect to the supply and demand of energy is provided and examples are given to illustrate how the final form of energy demanded by the consumer impacts the type of storage for an individual application. A top-down approach is used to determine the maximum acceptable energy storage costs based on the payback, the cost of energy, and the frequency of storage cycling. The frequency with which a storage operates has a defining impact on the maximum acceptable storage cost. Long-term storages are cycled infrequently and require low storage costs for economic viability. At present, long-term storage is economically viable only with sensible energy storage. For shorter storage periods, many more storage technologies are economically feasible. The economic limitations and consideration of the final energy demand are critical to selecting the appropriate storage technologies for each application.
