  1. Williams High-Power Flywheel Daniel Hertrich, P.Eng. Senior Hydro/Civil Engineer Renewable Power Business Unit

  2. High-Power Flywheel Systems – Mobile Applications Motorsport • Mobile solution developed by WF1 for KERS • Used for Porsche 911 GT3 R Hybrid • 2 x 80 hp motors connected to front wheels • Capture regen. braking energy going into turns, increased, 4WD power out of turns • Audi etronquattro placed 1st and 2nd in 24 hrs of le Mans

  3. High-Power Flywheel Systems - Technology • Magnetically Loaded Composite (MLC) • Lower eddy current losses in rotor • Lower heat gain – higher duty cycle • Body of rotor – filament wound carbon and glass fibre composite

  4. High-Power Flywheel Systems – Mobile Applications WHP activity • Contract with London Bus operator to retrofit with flywheels • Contract with UK operator of electric passenger rail to study replacing onboard resistor bank with flywheels

  5. High-Power Flywheel Systems - Technology • High power density for short term, cyclical storage 200 kW peak, 1.5 kWh storage • High duty cycle (>75%) without loss in performance • Long life (20 yrs) • Low standing loss (<1%) • High round trip efficiency (>96%) • Fast response time (full power <5ms)

  6. High-Power Flywheel Systems – Stationary Applications Rail Traction Systems • Energy savings (10 – 30%) by recovering regenerative braking energy • Voltage support • Emergency reserve

  7. High-Power Flywheel Systems – Stationary Applications Industrial / Mining Applications • Peak shaving of cyclical demands • Reduce capital requirements • Energy savings through capturing regenerative braking energy • More efficient operation of generating equipment

  8. High-Power Flywheel Systems – Stationary Applications Renewable Energy • Power conditioning • Voltage and frequency regulation • Wind - diesel systems • relaxes the operating constraints of diesel gensets – increased penetration of wind • Potential for diesel off operation in small systems

  9. High-Power Flywheel Systems – Energy Storage

  10. High-Power Flywheel Systems – Stationary Applications

  11. Typical Wind Diesel System in Alaska Data from ACEP and AIDEA 2011 PCE

  12. Analysis of Hybrid System in Alaska
