Pentadyne Introduces New Flywheel


October 06, 2009  |  2 Comments

Print

Pentadyne Power Corporation has introduced the next generation of its flywheel technology for uninterruptible power supply (UPS) systems. The new flywheel, branded GTX, delivers 25% more energy storage than the company's previous models.

The 25% increase in energy storage allows UPS customers to reduce the number of flywheels and the cost needed to bridge the gap between utility or renewable energy system power losses and transition to a back-up generator system.

“The Pentadyne GTX flywheel technology is unique in that our flywheel operates with no bearings and no vacuum pump, making the GTX flywheel highly reliable and virtually maintenance free. GTX is at least 10X more reliable than lead-acid batteries in delivering the energy needed to support mission-critical loads while engaging the back-up generator system,” said Claude Kalev, Pentadyne's CTO.

Technologies like the GTX are ideally suited for supporting hospital, data center and casino mission critical load applications. The flywheel uses about one quarter of the valuable space that batteries require and can operate in a wide temperature range, making them a possible solution for storing/backing up solar and wind power as well.

I've always wondered about flywheel storage for automotive and whether the gyroscopic forces would be a hindrance or could be used to benefit stability.

Although of course flywheels are the "greener" alternative to lead acid batteries and have some significant benefits over them it is misleading to state that the flywheel occupies one quarter of the space that batteries require. Batteries have a far greater energy density than flywheels will ever have, borne out by the fact that runtime calculations for flywheel technologies are calculated in seconds, whereas lead acid batteries are in minutes. A typical UPS with a flywheel will have a runtime in the region of 30-60s, whereas a standard battery will give 5-10minutes, ten times as much. So for four times the space you get ten times the energy. Given this ratio, you could argue that Ampere-hour for Ampere-hour, flywheels actually take up more room than lead acid batteries- over twice as much in fact.
