Subsequent Events [Abstract]
Subsequent Events	14. Subsequent Events The Company has evaluated subsequent events and transactions through the date of this filing for potential recognition or disclosure in the financial statements and has noted no other subsequent events requiring recognition or disclosure other than as stated below. On October 12, 2012, the Company received a deficiency notice from The Nasdaq Stock Market ("Nasdaq") stating that it no longer complies with Nasdaq Marketplace Rule 5550(a)(2) because the bid price of the Company's common stock closed below the required minimum $1.00 per share for the previous 30 consecutive business days. The notice also indicated that, in accordance with Marketplace Rule 5810(c)(3)(A), Plug Power has a period of 180 calendar days, until April 10, 2013, to regain compliance with Rule 5550(a)(2). If at any time before April 10, 2013 the bid price of the Company's common stock closes at $1.00 per share or more for a minimum of 10 consecutive business days, Nasdaq will notify the Company that it has regained compliance with Rule 5550(a)(2). In the event the Company does not regain compliance with Rule 5550(a)(2) prior to the expiration of the 180-day period, Nasdaq will notify the Company that its common stock is subject to delisting. The Company may appeal the delisting determination to a Nasdaq hearing panel and the delisting will be stayed pending until the panel's determination. At such hearing, the Company would present a plan to regain compliance and Nasdaq would then subsequently render a decision. The Company is currently evaluating its alternatives to resolve the listing deficiency.
