And Beacon Power, before its bankruptcy, focused largely on using flywheels as frequency regulators for power grids. But Ben Jawdat, the founder and CEO of Revterra, a flywheel startup based in Texas, thinks that his company has overcome the shortcomings, making flywheels capable of long-term energy storage for renewable energy.
Previous flywheel storage systems used either mechanical bearings, such as ball bearings, where the bearing physically touches the rotor, or active magnetic bearings, which eliminate friction at the cost of complex and power-hungry control systems.
In comparison, many flywheels consume over 1000 Watts, according to Jawdat. So if you charge the flywheel battery all the way and discharge completely, you would only lose about 10% of the energy, he adds. Improvements in superconductor manufacturing have made them more practical for commercial applications.
Another popular technique, compressed air energy storage, is cheaper than lithium-ion batteries but has very low energy efficiency—about 50%. Here is where Jawdat sees a market opportunity. Compared to lithium-ion batteries, flywheel batteries essentially last forever.
While the interest in flywheels soared in the late 1990s and 2000s, it had shortcomings. These early flywheel batteries were bad at storing energy for long periods.
