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. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the. . However, only a small percentage of the energy stored in them can be accessed, given the flywheel is synchronous (Ref. FESS is used for short-time storage and typically offered with a charging/discharging duration between 20 seconds and 20 minutes. A rotating mass, ideally spinning in a vacuum. The primary types include mechanical flywheels, magnetic bearings, and composite flywheel systems, which each utilize distinct technologies to optimize energy retention. .

Torus Spin—our flywheel energy system—provides the same stabilizing inertia to the grid as conventional power plants. . With solar and wind contributing 38% of East Asia's new power capacity in 2023 (Global Energy Monitor), energy storage has become critical. Unlike traditional batteries, flywheel systems offer: "Flywheel technology acts like a shock absorber for power grids – it doesn't store the most energy, but. . Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy. By providing multiple cycles of kinetic energy without chemical degradation, our flywheels are uniquly suited to support the transition from fossil fuels to sustainable renewable. . Our systems combine chemical batteries—Torus Pulse—and flywheel energy systems—Torus Spin—to provide significant performance advantages over chemical-only solutions.
