Superconducting Bearings for Flywheel Energy Storage
Introduction. Flywheels have long been used to store energy in the form of rotational kinetic energy. While past applications of the flywheel have used conventional mechanical bearings that had relatively high losses due to friction, the development of magnetic bearings constructed using High Temperature Superconductors (HTSC) has greatly decreased the …
Flywheels turn superconducting to reinvigorate grid storage potential
The flywheel has fallen off many people''s radar since the industry''s leader, Beacon Power, filed for bankruptcy in 2011. Though the company was revived shortly after—and other competitors joined the market since—the flywheel''s comeback to the mainstream hasn''t quite happened yet. But one startup is hoping to change that, …
