Energy storage systems score a hit in defence

Pentadyne Power Corp has received a follow-on order worth more than $2 million from Beaver Aerospace and Defense for an additional 46 systems over the course of the next several months.

Pentadyne Power Corp has received a follow-on order worth more than $2 million from Beaver Aerospace and Defense for an additional 46 DX-A2-rated (certified for national defence use) Pentadyne VSS+DC systems to be delivered over the course of the next several months.

This third in a series of purchase orders from Beaver Aerospace is part of a procurement contract with Pentadyne to be the exclusive supplier of more than 500 clean energy storage systems that will be deployed in homeland security military defence applications during the next few years.

"I'm proud Pentadyne was selected to be the exclusive supplier of flywheel-based clean energy systems for a vital array of national defence installations", said Pentadyne President and CEO Mark McGough.

"The superior performance and reliability of our VSS+DC clean energy storage flywheel systems over competing products was the overriding factor in Pentadyne being designated as the sole supplier in what we believe is the world's largest flywheel energy storage deployment programme".

Beaver Aerospace Program Manager Jim Diroff said: "We evaluated numerous energy storage technologies".

"Our multi-unit trials of Pentadyne systems over the past two years have confirmed their exemplary performance, exceeding the extremely demanding requirements of this application".

The Pentadyne VSS+DC is an advanced DC flywheel power system that stores energy kinetically instead of chemically, delivering stable, reliable, DC voltage for applications where power continuity is critical.

Flywheel energy systems can eliminate the need for hazardous, maintenance-laden batteries in uninterruptible power supply (UPS) systems, or they can be deployed as the first line of defence with battery arrays to dramatically improve battery longevity and reliability.

The flywheel system provides sufficient ride-through for short duration utility power outages (98% of which last less than 10 seconds) or until a backup generator can come online.

Capable of supplying a 225kVA load for more than 12 seconds (longer for lower demand), each VSS+DC module can be seamlessly paralleled without any communications gear for higher output, redundancy and/or longer duration power requirements.
