Torus Spin

Flywheel energy storage with a 10C rating, millisecond response, and a 25,000-cycle lifespan – built for power-intensive applications.

25,000 cycles

10C rating

Zero degradation

Torus Spin is a flywheel energy storage system built for high power output, fast cycling, and stabilizing frequency and voltage support. It delivers full power in milliseconds and absorbs the rapid load swings that wear down chemical batteries.

20x power density

A 10C discharge rating delivers 20 times the power-to-energy ratio of traditional battery energy storage systems.

Zero capacity degradation

Spin stores energy mechanically rather than chemically, so it doesn't lose capacity over time. Day-one performance and year-20 performance are the same.

6-minute discharge

Spin is designed to complete a full cycle discharge in 6 minutes, handling multiple events in quick succession. 

25,000 cycles

Spin holds a 25,000-cycle lifespan with minimal maintenance requirements.

Built for fast, high-power events

The hardest power problems don't unfold over hours. They happen in milliseconds.

Manufacturing and industrial

  • Flatten the highest 15-minute peak every billing cycle
  • Discharge and recharge in 12 minutes to handle loads that spike in series
  • Correct voltage sags before they trip a single line
