The $200 Million Spinning Wheel Revolution – Torus Flywheel Energy Storage

American energy storage company Torus just secured $200 million from Magnetar Capital for a technology that could fundamentally change grid economics: massive spinning wheels that store electricity for 25 years.

While the industry focuses on incremental battery improvements, Torus is scaling flywheel energy storage to utility level. Their hybrid approach combines millisecond-response flywheels with traditional batteries, extending battery life while providing instant grid stabilization.

Key metrics driving investor confidence:

 

99.9% uptime across 230+ installations in 2025

500 MW utility contracts with PacifiCorp

25-year operational lifespan vs 3-5 years for batteries

Already deployed at Salt Lake City Airport and industrial facilities

 

The economics are compelling: replace one flywheel system every 25 years versus 5-8 battery replacements over the same period.

What's your take on mechanical vs chemical energy storage for grid applications?
