The application of fuel cell technology to rail transport operations

Abstract

Fuel cell technology has in recent years undergone a period of rapid development. This evolution has been driven by the requirements of developed countries to reduce the emission of greenhouse gases, with particular emphasis placed on reducing CO2 emissions. This article discusses the possibility of using fuel cell technology for rail vehicle propulsion, with the United Kingdom chosen as a case study. A brief review of fuel cell technology and its application within the UK is presented. It is concluded that, although the technology for fuel cell power will be suitable within the next few years, its adoption by mainline UK rail operators will be delayed considerably until existing diesel vehicles have reached the end of their useful life. By this time the technology of fuel cells will be well proven within other transport markets and its transfer to rail markets will be facilitated. This will be augmented at this time by increasing diesel fuel prices. However, the adoption of fuel cell technology for light rail/tram systems does offer advantages in terms of infrastructure development and aesthetics which could make it a serious option for new and upgraded light rail/tram schemes.
