Definition:
A mechanical energy storage system that stores kinetic energy in a rotating mass (flywheel) and releases it as electricity when needed.
Key Components:
- High-speed rotating flywheel
- Vacuum-sealed housing for friction reduction
- Power conversion system
Use Cases/Industries:
- Frequency regulation in power grids
- Backup power for critical applications
- Electric vehicle energy recovery
Advantages:
- High efficiency and long lifespan
- Instant response time for grid stabilization
- No chemical degradation like batteries
Challenges:
- Limited energy storage duration (minutes to hours)
- High initial cost for advanced flywheel systems
- Requires continuous rotation to maintain charge
Related Terms:
Energy Storage System (ESS), Grid Stability, Frequency Regulation
Example:
Flywheels are used in data centers to provide short-term power backup while diesel generators start up.
