Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10, up to 10, cycles of use), high specific energy (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The energy efficiency (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 kWh to 1
In transportation, hybrid and electric vehicles use flywheels to store energy to assist the vehicles when harsh acceleration is needed. 76 Hybrid vehicles maintain constant power, which keeps running the vehicle at a constant speed

Because they can be placed almost anywhere, flywheels can be located close to the consumers and can store electricity for distribution. While a single flywheel device has a typical capacity on the order of kilowatts, many
A 1,000kg, 5m, 200RPM flywheel would store 685,567J of energy if it was shaped like a disc. That''s 0.19kWh of energy — enough to boil the water for about seven (7) cups of tea or run a typical airconditioner for
The moment of inertia plays a crucial role in this process, affecting how much energy a flywheel can store. The energy stored by a rotating flywheel can be calculated using: [ E = frac{1}{2} I

Our flywheel energy storage calculator allows you to compute all the possible parameters of a flywheel energy storage system. Select the desired units, and fill in the fields related to the quantities you know: we will immediately compute
Calculations based on the above formula allow designers to predict how much energy the flywheel can store when it rotates. Consider a flywheel with a mass of 5 kg and a radius of 0.4 m. The
A flywheel system stores energy mechanically in the form of kinetic energy by spinning a mass at high speed. Electrical inputs spin the flywheel rotor and keep it spinning until called upon to release the stored
A flywheel system stores energy mechanically in the form of kinetic energy by spinning a mass at high speed. Electrical inputs spin the flywheel rotor and keep it spinning until called upon to release the stored energy. The amount of energy available and its duration is controlled by the mass and speed of the flywheel.
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.
Their efficiency is high during energy storage and energy transfer (>90 %). The performance of flywheel energy storage systems operating in magnetic bearing and vacuum is high. Flywheel energy storage systems have a long working life if periodically maintained (>25 years).
Small applications connected in parallel can be used instead of large flywheel energy storage systems. There are losses due to air friction and bearing in flywheel energy storage systems. These cause energy losses with self-discharge in the flywheel energy storage system.
Our flywheel energy storage calculator allows you to calculate the capacity of an interesting type of battery!
Recent interest in space applications of flywheel energy storage has been driven by limitations of chemical batteries for Air Force and NASA mission concepts. FES was designed to replace the nickel hydrogen (NiHz) battery orbital replacement units in the ISS Electric Power System.
