Natural Gas Alternatives

Energy Conversions Inc. (ECI) designs and manufactures natural gas and dual fuel or bi fuel systems for diesel engines common to power generators, offshore drilling, industrial and locomotive industries.

In the early 1990's, Energy Conversions was the first to commercially demonstrate a natural gas powered locomotive. The ECI retrofit system, which converts a General Motors EMD diesel engine to dual fuel operation (some call Bi fuel), uses electronically controlled direct fuel injection and is capable of full horsepower high fuel replacements (90%) while substantially reducing emissions. Now offering spark ignition for EMD engines and the Economizer systems for a more simplified conversion of four stroke diesel engines

Today, ECI continues to develop and implement their natural gas systems for power generators, locomotives and various power applications worldwide while researching new avenues of alternative fuel use.

Other alternative fuels that ECI has interest in, DME and Hydrogen both demonstrate very clean alternatives to today's fuels. Development in infrastructure and fuel cost will be the determining factor

News Briefs

      Norfolk Southern Railway project is picking up speed. The spark ignition locomotive switcher project is expected to see commissioning before the end of 2014

    Aggreko has been commissioning several ECI Economizer systems in Russia and Thailand October 2014

   Thailand: with the help of our distributor Precision Power Services, ECI commissioned the second Cummins KTA50 generator set on Mubadala Ban-Yen platform 3/25/14

   GES in Dominican Republic has their fourth 3516 generator system commissioned and the other 3 units tuned up for optimum operation

   Heartland Mill commissions its Cat 3406 generator reaching over 70% diesel replacement. The date 10/11/12 will go down in infamy (at least for us) :) Thank you Heartland Mills

   Canadian National is making application of the ECI EMD conversion system to 2 of their SD40-2 locomotives. The systems delivered earlier this year have been commissioned and placed in revenue service end of October 2012.

   Indian Railroad commissions the first of 10 DEMU passenger locomotives for dual fuel. ECI with the help of our distributor CLH in New Delhi has delivered our order for two units and have completed the first step in the program in record time. June 2012

   January 2012, Laesa applies conversion systems to two more of the mighty Wartsila 18V32's making a total of four. Fuel supply is LNG based.

     Napa Valley Railroad continues to operate one of its locomotives with 100% gas. Now with the increasing price of diesel, operation with gas is more than just cleaner its a lot cheaper.

    ECI tests dual fuel operation with bio diesel proving identical operation while blending alternative fuels

    Global warming on your mind? Natural gas is a perfect midterm solution. Natural gas is the highest hydrogen to carbon ratio fuel. Engines running natural gas with diesel typically have 20 to 30% less CO2 emissions. When you are talking about the single largest pollutant from exhaust, 20% is a huge number.
