Flywheel Energy Storage Nova Spin Our flywheel energy storage device is built to meet the needs of utility grid operators and C&I buildings.
First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. To reduce friction, magnetic bearings are sometimes used instead of mechanical bearings.
The net energy ratios of steel and composite flywheels are 2.5–3.5 and 2.7–3.8. The GHG emissions of steel and composite flywheels are 75–121 and 49–95 kg CO 2 eq/MWh. Flywheel energy storage systems are feasible for short-duration applications, which are crucial for the reliability of an electrical grid with large renewable energy penetration.
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.
Environmental and energy performance indicators are an important part of the investment decisions prior to the deployment of utility-scale flywheel energy storage systems. There are no published studies on the environmental footprints of FESSs that investigate all the life cycle stages from cradle-to-grave.
A 30 MW flywheel grid system started operating in China in 2024. Flywheels may be used to store energy generated by wind turbines during off-peak periods or during high wind speeds. In 2010, Beacon Power began testing of their Smart Energy 25 (Gen 4) flywheel energy storage system at a wind farm in Tehachapi, California.
A flywheel is not a flying wheel, though if things go sideways, it's possible to find flywheels mid-air. Flywheels are devices used to store energy and release it after smoothing eventual oscillations received during the charging process. Flywheels store energy in the form of rotational energy.
