Altergy's Fuel Cells achieve energy milestone - over 5 million hours of operation

Altergy Systems 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" hydrogen fuel cell systems have accumulated over 5 million operational hours.

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 fuel cell electrical power generators provide clean safe power at the point of use -- eliminating the need for batteries and generators. 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 demand immediate and long lasting reliability. The sporadic limitations of these other power systems cannot successfully address those power demands on a continuous or 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."
