Flywheel Energy Storage
Flywheel energy storage is a mechanical energy storage technology that stores kinetic energy in a rotating mass (flywheel) to provide short-duration power backup or grid stabilization. It works by accelerating a rotor to high speeds using an electric motor, then converting the stored rotational energy back to electricity via a generator when needed. This technology is valued for its high power density, rapid response times, and long operational lifespan with minimal degradation.
Developers should learn about flywheel energy storage when working on renewable energy integration, uninterruptible power supply (UPS) systems, or grid-scale energy management projects, as it excels in applications requiring fast discharge rates and frequent cycling. It is particularly useful for smoothing power fluctuations from intermittent sources like wind and solar, providing backup power for data centers or critical infrastructure, and enhancing grid frequency regulation due to its ability to respond within milliseconds.
