Composite flywheels: status and performance assessment and projections
Conference
·
OSTI ID:6320395
Prototype composite energy-storage flywheels that have evolved from the US Department of Energy/Lawrence Livermore National Laboratory flywheel-development program are described. The flywheels produced by Garrett AiResearch and General Electric Company have demonstrated high energy-storage performance and durability in ultimate-speed and cyclic-spin tests. Ultimate energy densities as high as 72.8 Wh/kg (702 Wh) and 114 kWh/m/sup 3/ have resulted with a design potential up to 100 Wh/kg ultimate. Low-cost rotor designs are also discussed and ultimate-speed spin-test results reported. Progress in understanding the failure modes and containment behavior of these rotors and plans to test burst containment within prototype flywheel housings are noted.
