GreenMan Subsidiary Secures $0.3M Dual Fuel Conversion Order With Bhushan Steel Ltd.

Follow-On Order for Conversion of Two of the Largest Stationary Generators in the World

CARLISLE, IA--(Marketwire - December 21, 2010) -  GreenMan Technologies, Inc. (OTCBB: GMTI) announced that its American Power Group Inc. (APG) subsidiary has received a follow-on order from Bhushan Steel Ltd., ("Bhushan Steel") New Delhi, India, to convert two MAN B&W 12.3MW generators at their Khopoli industrial site to APG's dual fuel technology. Bhushan Steel has been operating two 12.3MW generator sets which were retrofitted with APG's dual fuel technology in 2006 and are considered to be one of the largest dual fuel engines operating in the world. The $0.3 million order is scheduled for completion during the first quarter of 2011. Bhushan Steel Ltd. is India's third largest secondary steel provider with estimated capacity of 2 million tons per annum. The company has three manufacturing facilities in the states of Uttar Pradesh, Maharashtra, and Orissa. 

APG's dual fuel system converts diesel engines and generators to function more efficiently and at a lower operating cost (net fuel cost savings of 25% - 35%) by seamlessly displacing 40%-70% of the normal diesel fuel consumption with CNG, LNG, or bio-methane. APG's system is non-invasive to the OEM engine and operates within all OEM performance controls with the flexibility to return to 100% diesel operation at any time. APG's dual fuel conversion and emissions reduction systems can help users achieve their sustainability goals through lower carbon monoxide, nitrogen oxide, and particulate matter emissions. In addition, the introduction of natural gas through APG's dual fuel system does not impact diesel engine performance and will also assist in extending the engine's oil life as natural gas is a cleaner burning fuel compared to diesel.

Lyle Jensen, GreenMan's President and Chief Executive Officer stated, "This opportunity is a prime example of the diversity of applications for our patented dual fuel solution. In the case of Bhushan Steel, we are installing our dual fuel technology on two generators (12.3MW each) which are used to supply primary energy for the operation of Bhushan's steel rolling mills and are the size of two greyhound buses stacked on each other. This is in stark contrast to several smaller applications (less than 100kw) identified in the oil patch and residential markets which are approximately 1/25th the size of the Bhushan generators. Our ongoing efforts and investments to enhance the functionality and cost competitiveness of our dual fuel technology is why we can offer cost effective solutions in such diverse markets. India is quickly becoming a large market for both generator and vehicular CNG dual fuel opportunities and we look forward to building upon our relationship with Bhushan Steel.
