GreenMan Technologies' Subsidiary Signs Distributor Agreement for the Dominican Republic

LYNNFIELD, MA--(Marketwire - Jul 28, 2011) - GreenMan Technologies, Inc. (OTCQB: GMTI) (PINKSHEETS: GMTI) announced that its APG International Inc. subsidiary ("APGI") has entered a dual fuel distribution agreement with Caribbean Power Group CPG S.R.L. which has its headquarters in Santo Domingo. The agreement will cover sales, marketing and installation of APGI's dual fuel system for both diesel generators and diesel-powered vehicles.

Dominican Today previously reported that President Leonel Fernandez had launched the "Program to Implement the Use of Compressed Natural Gas In Vehicles" which is a plan to switch at least 20,000 public transport vehicles to natural gas. The objective is to establish four major corridors with natural gas fueling stations from Santo Domingo to different regions of the country. The government wants the use of natural gas to become a national priority.

APG's dual fuel system converts diesel engines and diesel generators to function more efficiently and at a lower operating cost (average net fuel cost savings of 20%-35%) by seamlessly displacing up to 40%-60% of the normal diesel fuel consumption with either CNG, LNG, pipeline gas, well-head gas, or other qualified bio-methane gases. 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 power or torque and will 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, "It was recently reported that the Dominican government issued 65 new licenses to companies which market natural gas and related natural gas activities underscoring their commitment to implementing the needed infrastructure to make natural gas vehicles a reality. We are also seeing notable interest from the private sector for both power generation and vehicular natural gas applications."
