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.
