"Flywheel-based energy storage systems, unlike lead-acid batteries, are sustainable â€œgreenâ€ technology solutions that do not use hazardous materials for production, nor create them during operation. Unlike batteries, flywheels operate reliably for many years with little or no maintenance. Their life cycle cost benefits and ROI have proven to be far superior to those of lead-acid batteries. Despite higher initial costs, flywheels offer an attractive and long-term cost-effective energy storage alternative for the canadian pharmacy cialis generic growing number of companies implementing sustainable business practices."
Flywheels have been used for years to provide uninterruptible power supplies, but Beacon Power has developed a system that can be used for grid level power balancing, which is orders of magnitude greater. Beacon's system has just received certification from California's Independent System Operator - the not-for-profit corporation that operates Californiaâ€™s high-voltage electrical grid.
Flywheels are also likely to gain increasing use as wind and other intermittent generators become more prevalent. At the other end of the scale, small scale flywheels may make it easier for homes and small businesses to be completely off the grid by storing excess power their systems generate in peak periods of cheap canadian pharmacy sun or wind, and drawing on that stored energy during slack periods.
