Altergy's Freedom Power™ Systems Achieve Major Clean Energy Milestone - Over 5 Million Hours of Safe Zero Emission Operation

FOLSOM, California – March 23, 2011 – Altergy Systems (Altergy) is pleased to announce that its international fleet of deployed Freedom Power Systems has achieved yet another major milestone: These clean and safe “zero emission” systems have accumulated over 5 million operational hours.

Altergy - The Telecom Solution

Altergy’s Freedom Power Systems are providing both continuous power and back-up power to the telecommunications industry and others worldwide.

Altergy’s zero emission electrical fuel cell power generators provide clean safe power at the point of use -- eliminating the need for batteries and the grid. They provide high reliability, long runtime, a small footprint, low weight, long life, low maintenance, and low noise while also affording a low up front capital cost and the lowest total cost of ownership.

Unlike solar or wind power, Altergy’s Freedom Power Hydrogen Fuel Cell power systems provide true uninterrupted power supply (UPS). Mission critical applications such as telecommunications and various other crucial back up power demands immediate and long lasting reliability. The sporadic limitations of other alternative energy systems cannot successfully address these power demands on a continuous uninterrupted basis.

“Surpassing 5 million hours of actual field operation is a major achievement.” says Altergy CEO Eric Mettler “We’re extremely proud that our Freedom Power Systems are now providing clean and safe zero emission power in thousands of locations around the world. “

“The world has long waited for fuel cells to demonstrate their capability as the true “work horse” in alternative energy.” he adds “We feel this achievement shows the dramatic and expanding role, importance, and advantages of hydrogen fuel cell power in solving the world’s current and future clean energy demands.”
