Plug Power Secures $6.5 Million Strategic Investment From Air Liquide

Investment Is Endorsement of Plug Power's Hydrogen Fuel Cell Strategy by World
Leader in Industrial Gas Products

LATHAM, N.Y., May 8, 2013 (GLOBE NEWSWIRE) -- Plug Power Inc. (Nasdaq:PLUG), a

million (Euro 5 million) strategic investment from its partner Air Liquide,

great validation of Plug Power's strategy," said Andy Marsh, Plug Power

liquidity we need for growth. But the endorsement and board expertise we also
get is just as important."
