The electric company maintains in its advertising, and correctly that you cannot store electricity but you can store energy. As a consequence we initially think of the battery; the most recognized energy storage device, and it is only fairly recently in the batteries 100 plus year history that it became the “U” in UPS as providing uninterruptibility.

Most recently, batteries are undergoing a change. Even a metamorphosis from lead acid to a wide variety of metals all designed to improve reliability. Concurrently, other devices are entering into the realm of energy storage technology as alternatives. One of these with a 4000 year-old history is the flywheel. In this instance chemical storage is replaced by kinetic energy storage.

This session examines battery storage technologies presenting the latest efforts to improve reliability. Included in the discussion are new battery developments, primarily related to use with the UPS. The flywheel as a kinetic energy storage device is also presented. However, it is examined from a perspective of being a very flexible use storage system going beyond the UPS and into other power quality/reliability applications.
