Senior analyst Dave Hurst believes that we shall see growth in world use of hybrid locomotives due to “new diesel locomotive emissions regulations scheduled to go into effect in the European Union in 2014 and in North America in 2015″. New regulations will result in real change: exhaust treatments and retiring the most polluting engines. Hurst also notes that “railroad infrastructure is growing rapidly in India and China, and emissions concerns will drive hybrid demand in those markets as well.”

According to Green Car Congress, Pike Research anticipates that the demand for less polluting locomotives and greater adoption of hybrid locomotives “could have a positive effect on batteries for other industry sectors. ” Hybrid locomotives use very large capacity batteries; “senior analyst Dave Hurst states that new sales of hybrid locomotives will require approximately 514 megawatt hours (MWh) of battery capacity between 2011 and 2020.”
