Plug Power Receives Fuel Cell Order From National Retailer

VANCOUVER, British Columbia, Oct. 22 /PRNewswire-FirstCall/ -- Plug Power Inc. , through its wholly owned subsidiary Cellex Power Products, Inc., today announced a purchase order for GenDrive(TM) fuel cell power units from Wal-Mart Stores, Inc. for use in lift trucks at one of the company's distribution centers. This is Plug Power's largest single GenDrive order to date, although the specific terms are confidential.

The order follows a successful beta trial at two Wal-Mart distribution centers in Ohio in late 2006. During the trial, the 12 fuel-cell-powered pallet trucks ran in live, working conditions for more than four months, logging more than 18,000 hours and 2,100 indoor fuelings by pallet truck operators. The Cellex Power fuel cells demonstrated environmental and operator benefits. The new units will power pallet trucks used at Wal-Mart's food distribution center in Washington Court House, Ohio, replacing the lead- acid batteries that are traditionally used in such applications.

"This is a significant event for Plug Power and a solid step forward with the widely respected leader in distribution and logistics," said Tom Hoying, Plug Power's vice president of sales and customer operations, Motive Power Division. "We believe Wal-Mart's state-of-the-art distribution centers make an excellent proving ground for the commercial application of GenDrive."

This fuel cell order aligns with Wal-Mart's strategy to integrate innovative technologies into its business plan that reduce operating cost and help the environment. The purchase of these fuel cell power units is equivalent to removing approximately 60 cars from the highway in southeastern Ohio in terms of CO2 and greenhouse gas emissions.

"We've seen how fuel cells can improve efficiency in our distribution centers while enabling us to be more responsible global citizens," said Johnnie Dobbs, Wal-Mart's executive vice president of logistics and supply chain. "Wal-Mart is focused on finding ways to improve our relationship with the environment throughout our operations. Our hope is that our investment in fuel cell technology will encourage its development as a viable option to existing technologies."

For pallet trucks and similar industrial vehicles operating in large, around-the-clock fleet operations, lead-acid battery systems can be more expensive to operate and require more valuable space when compared with fuel cell power units. Lead-acid batteries also require documentation demonstrating proper disposal and present other safety issues in terms of care and handling. Plug Power's GenDrive product eliminates the need to change, charge, maintain and handle batteries in these high-throughput distribution centers, which could result in cost improvements and productivity gains.

Plug Power, which acquired Cellex Power in April 2007, considers material handling applications to be an attractive near-term market for proton exchange membrane (PEM) fuel cell power and has targeted this sector as a central component of the company's revenue growth strategy.

"We view Wal-Mart's purchase order as an important indicator of the progress that fuel cells are making as reliable and clean alternatives to incumbent technologies in a variety of industries," said Roger Saillant, Plug Power's President and CEO.
