6 Frequently Asked Questions about “Flywheel Energy Storage and UPS”
What is a direct current flywheel energy storage system?
Advances in power electronics, magnetic bearings, and flywheel materials coupled with innovative integration of components have resulted in direct current (DC) flywheel energy storage systems that can be used as a substitute or supplement to batteries in uninterruptible power supply (UPS) systems.
Can flywheel energy storage be used in ups?
Coupled with seemingly ever-increasing needs for more reliable, higher quality power, the long-run prospects for flywheel energy storage in UPS applications looks good. Manufacturers of flywheels for applica tion in UPS systems were primarily identified via searching Internet web sites. This search was conducted dur ing fall 2002.
What are DC flywheel energy storage systems?
As indicated throughout this Federal Technology Alert, DC flywheel energy storage systems are an alternative or supplement to lead-acid batteries. Bat teries have the advantage of providing backup power for a period measured in minutes rather than seconds, but this advantage has limited value if reliable backup generators are available.
What is flywheel energy storage?
However, there has been a steady growth in the flywheel energy storage market as technology has improved. A flywheel is essentially a rotating mass that spins at incredible revolutions per minute (RPM). This spinning disc is typically housed in vacuum to reduce resistance and is used to convert kinetic energy to produce DC power.
Can a flywheel replace a battery in a UPS system?
Flywheels appear poised to replace or supplement batteries as a backup power supply in UPS systems. Six companies currently offer DC flywheel energy storage products. Another half dozen or so are developing products they expect to bring to market within the next few years.
Do flywheels save energy?
The federal government, responsible for a broad spectrum of critical services, represents about 5% of the total UPS market in the United States. The primary attractions of flywheels in UPS applications are not energy savings. Instead, flywheels offer the possibility of improved UPS system reliability and reduced life-cycle costs.
