Mercedes-Benz Expands Use of Plug Power Hydrogen Fuel Cells at Vehicle
Assembly Plant in Tuscaloosa, Alabama

Construction of New Logistics Hub Drives Purchase of 123 Additional Lift
Trucks Powered by GenDrive Fuel Cells

LATHAM, N.Y., Aug. 20, 2013 (GLOBE NEWSWIRE) -- Plug Power Inc. (Nasdaq:PLUG),
a leader in providing clean, reliable energy solutions, today announced that
Mercedes-Benz US International, Inc. (MBUSI) has ordered 123 additional
hydrogen-based GenDrive^® fuel cell units to power new forklift trucks for its
material handling fleet at a logistics hub now under construction in
Tuscaloosa, AL.

Last July, Mercedes purchased 72 GenDrive fuel cells for the lift truck fleet
at its Tuscaloosa vehicle assembly plant. Earlier this year, construction
began on a brand new $70 million, 900,000 square-foot state-of-the-art
warehouse. This new facility is designed to streamline logistics operations
and support the receiving, handling and sequencing of parts for M-Class and
GL-Class SUVs and R-Class crossover vehicles currently in production, as well
as for the successor generation of the current C-Class for the North American
market beginning in 2014. It is expected that the new GenDrive-powered
forklift fleet will be operational by the fourth quarter of 2013.

Plug Power's GenDrive fuel cell is designed as a drop-in replacement for
lead-acid batteries. It is a more efficient, cost-effective method of
providing clean energy for warehouse and distribution operations. Not only
does fuel cell usage eliminate the possibility of lead and acid contamination
in the workplace, it also eliminates the need for battery storage and
re-charging rooms in the new logistics hub.

Compact refueling stations will be available in several locations within the
facility, with hydrogen provided by Air Products (NYSE:APD). Fuel cells take
only minutes to fully re-fuel, whereas batteries can take hours to reach
maximum charge. In addition, fuel cells keep lift trucks running at constant
speed, unlike batteries, which cause vehicles to slow as their charge runs

"The Mercedes-Benz plant in Tuscaloosa has experienced first-hand the value of
GenDrive fuel cells to operate its forklift fleet," said Andy Marsh, CEO of
Plug Power. "Success with their initial implementation has led Mercedes to
broaden their commitment to sustainable energy by ordering even more GenDrive
units to power the fleet in their new logistics center."

It is anticipated that the coming logistics center, which will be as large as
the current vehicle assembly plant, will receive about 240 semi-trailer truck
deliveries daily and the GenDrive hydrogen fuel cell-powered lift trucks will
handle approximately 2.9 million automotive parts per day.
