Plug Power Announces Additional Site for Procter & Gamble

Fuel Cells Now Powering Lift Trucks at Four P&G Manufacturing Facilities

LATHAM, N.Y., Nov. 29, 2012 (GLOBE NEWSWIRE) -- Plug Power Inc. (Nasdaq:PLUG),
a leader in providing clean, reliable energy solutions, today announced that
Procter & Gamble Co., (NYSE:PG) has selected its GenDrive® fuel cell products
to power its electric lift truck fleet in its manufacturing facility located
in Mehoopany, PA. This additional facility now brings to four the number of
sites converting to GenDrive fuel cells. Over 340 units will now be deployed
throughout Procter & Gamble's manufacturing infrastructure. Additional P&G
sites using green fuel cell technology include facilities in California, North
Carolina and Louisiana.

Unlike the incumbent technology, GenDrive is powered by hydrogen, ensuring
constant voltage to the truck and has a 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. Since GenDrive is
powered by hydrogen, an emerging clean-energy fuel, it is estimated that
greenhouse gas emissions are reduced by more than 60 percent.

"Plug Power's GenDrive product is delivering increased fleet productivity,
decreased facility operating costs and reduced greenhouse gas emissions at
customer sites throughout North America," said Andy Marsh, CEO at Plug Power.
"P&G is one of six Fortune 100 companies to convert multiple facilities to
GenDrive fuel cells. With this fourth site conversion, P&G will lessen its
environmental impact while realizing increased productivity, reduced operating
costs and better predictability of its fleet performance."
