Quick Response for Special Needs. Task 75. Guiding the Selection and Application of Wayside Energy Storage Technologies for Rail Transit and Electric Utilities

Rail transit is experiencing increased ridership as a byproduct of the recent rise in price of gasoline that is further taxing the nation's rail systems. At the same time, the price of electricity that powers rail transit systems is rising because of the nationwide rapid growth in electrical demand and the limited capacity of a strained electrical grid. Further, existing rail power substations may be inadequately equipped to support running heavier trains with more passengers; operating higher performance trains; and operating more frequent trains on shorter headways. There is a way out of this dilemma for rail transit systems in the form of trackside energy storage systems, which would recycle regenerated energy from braking, reduce voltage sag between existing substations, and reduce peak power demands thereby reducing electric utility costs. Trackside energy storage units in the form of advanced batteries, electrochemical capacitors and flywheels have come a long way in recent years and some of which have been successfully applied in Europe and Japan. Energy storage in general, other than a few scattered past trials, is very new to US transit agencies. The average transit agency is overwhelmed by the need to amass knowledge on new storage technology quickly, and to learn how to efficiently perform engineering analyses needed to define the design and operation of energy storage technologies. They also need to understand the current state of energy storage technology, the role of utilities as potential partners, and the expected direction of new research and its affect on transit operations.
