Mercedes-Benz will realize greater fleet predictability and flexibility with the use of GenDrive hydrogen fuel cells units.

LATHAM, NY – July 18, 2012 – Plug Power Inc. (NASDAQ: PLUG), a leader in providing clean, reliable energy solutions, today announces that Mercedes-Benz U.S. International, Inc. (MBUSI) has purchased 72 GenDrive® hydrogen fuel cell units to operate its Hyster electric lift truck fleet in Tuscaloosa, Alabama. The GenDrive fuel cells will power a portion of the automotive plant's lift truck fleet.

Mercedes-Benz will realize greater fleet predictability and flexibility with the use of GenDrive hydrogen fuel cells units. The GenDrive units will replace lead-acid batteries, which require space-consuming charging areas and an expensive maintenance infrastructure. Compact hydrogen stations provided by Air Products (NYSE: APD) will be located onsite for a more efficient refueling process. As it grows its operations, Mercedes-Benz can add fuel cells to its fleet, without the need to invest in additional batteries, charging space or dedicated employees.

"Mercedes-Benz is an exciting customer to add to Plug Power's growing list of fuel cell adopters," said Andy Marsh, CEO at Plug Power. "We intend to prove the value of GenDrive fuel cells in Tuscaloosa in order to reinforce the benefits experienced in auto-manufacturing facilities across North America."

Unlike the incumbent technology, GenDrive is powered by hydrogen, ensuring a constant flow of power to the truck and fueling cycle that takes just minutes. Lead-acid batteries need to be changed, charged, stored and maintained, a process that is timely and involves costly infrastructure. With this conversion, Mercedes-Benz is able to eliminate its battery room and open that valuable floor space up for storing and moving product. Finally, because GenDrive is powered by hydrogen, a clean-energy fuel, only heat and water are generated as byproducts of electricity creation.

Plug Power has shipped and commissioned the full unit order.
