Abstract

This work offers an insight into both the theoretical possibility and practical challenges surrounding the use of hydrogen fuel cells to power the Class 66, one of the most popular intermodal freight locomotives. Results are presented for a test route constructed out of the most challenging sections of the West Highland line in Scotland, where hydrogen powered trains are most likely to operate. The forward model of the Class 66 models the dynamics effectively. The data from the inverse model is then used in Inverse Simulations, where many different methods are trialled. All methods reproduced the tractive force time history from the forward model effectively. Powertrain components were then chosen on the basis of the inverse simulation results, in particular the high gain method. It was found for a hypothetical 14km test route that a hydrogen fuel cell system containing 14 200kW fuel cells would be able to cover the power requirements of the locomotive and consume 39.942 kg of hydrogen. Alternatively, a hybrid configuration with 8 fuel cells and 5 60 kWh batteries would also cover the power levels, with the added benefit of using comparatively less hydrogen at 22.824 kg. The mass of the fuel cell only powertrain and the hybrid powertrain would be 12.25 and 16.25 tonnes, respectively, with the omission of power electronics. The final conclusion is that it is most certainly possible
