American Power Group Inc. Announces Collaboration With EQT Corporation and Linde North America on the Completion of the First Dual Fuel Rig Conversion in the Marcellus Shale Region Using Liquefied Natural Gas

LYNNFIELD, MA--(Marketwire - Jul 9, 2012) -  GreenMan Technologies, Inc. (OTCQB: GMTI) announced that its American Power Group Inc. (APG) subsidiary has worked with EQT Corporation (EQT) and Linde North America (Linde) to complete the first dual fuel rig conversion in the Marcellus Shale using liquefied natural gas ("LNG"). EQT's initial rig conversion is operating in Northern West Virginia. Pending evaluation of the economic, operational, and environmental benefits of EQT's pilot program, EQT plans to convert additional rigs in West Virginia and Pennsylvania. Compared to diesel-only engines, APG's dual fuel Turbocharged Natural Gas™ system emits less carbon dioxide, nitrous oxides, sulfur oxides, and particulates. The LNG being used for EQT's pilot program is produced locally from the Marcellus natural gas reserves. 

In a recent EQT Press Release, Steve Schlotterbeck, President of Exploration and Production for EQT, stated: "We want to be a leader in reducing the environmental impact related to drilling and are proud to be the first operator in the Marcellus to launch such a program. We continually look for opportunities to improve our operations and displacing diesel, by introducing the use of alternatives such as LNG and
field gas, is one way of doing so."

Lyle Jensen, GreenMan's President and Chief Executive Officer, stated, "We are pleased that EQT has selected our APG Turbocharged Natural Gas™ system for this important maiden launch in the Marcellus region. We see an ever expanding demand for LNG dual fuel applications in the oil and gas, marine, industrial, and heavy-duty vehicular end markets. This local EQT pilot program is one more important step in reducing emissions and our dependence on foreign oil imports." 

Mr. Jensen added, "We also are pleased to see our recently announced marketing relationship with Linde North America begin to generate revenue. APG is having notable success in converting diesel engines and diesel pumps with well-head and pipeline gas but a majority of the rigs are not logistically close to these sources of fuel so LNG makes perfect sense."
