Pennsylvania Wants Beacon Power’s Flywheel Energy Storage

Pennsylvania Wants Beacon Power’s Flywheel Energy Storage

excel at this requirement. Response times are measured in fractions of a second. “This is remarkable new technology that will help lower the cost of electricity in the long run,” said U.S. Representative Lou Barletta (PA-11). During off-peak times, Beacon’s magnetically supported flywheels are spun up to 1500 mph in a vacuüm (16000rpm.) When the power is needed, the inertia is drawn off to generate electricity. The 25-kWh units can be combined to achieve the required capacity. It is in the nature of flywheels that speed increases energy storage faster than the weight of the flywheel. Beacon Power says: “flywheel technology consumes no fuel, produces zero emissions of any kind, and can perform faster and more cost-effectively [than spinning reserve.]” Water usage by power plants is an increasing concern , as well. The Beacon facility does not require water cooling in its op...
