Flywheel Energy Storage Systems present a highly effective, sustainable, and economical alternative to traditional battery storage, particularly for grid-interactive buildings. Their application in commercial properties, universities, and hospitals offers numerous benefits, including fast response times, longevity, and low environmental impact.
Hospitals with grid-interactive technology can integrate flywheels as a reliable, quick-response energy source. In cases of power loss, flywheels can seamlessly transfer energy to critical systems while other backup systems, such as generators, come online.
A flywheel stores energy that is based on the rotating mass principle. It is a mechanical storage device which emulates the storage of electrical energy by converting it to mechanical energy. The energy in a flywheel is stored in the form of rotational kinetic energy.
The flywheel as a means of energy storage has existed for thousands of years as one of the earliest mechanical energy storage systems. For example, the potter’s wheel was used as a rotatory object using the flywheel effect to maintain its energy under its own inertia .
Thanks to the unique advantages such as long life cycles, high power density, minimal environmental impact, and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining attention recently.
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
