Exploring hydrogen fuel cell and battery freight locomotive options using train dynamics simulation

Spiryagin, Maksym / Cole, Colin / Schindler, Christian F. / Bosso, Nicola / Sun, Yan / Wu, Qing

As efforts are being made to quickly adopt zero carbon technologies and replace fossil fuel powered trains, the design requirements are explored using train dynamics simulations to establish energy needs. The test case was a freight train of 3030 gross tonnes consisting of two locomotives and thirty wagons operating on a relatively flat coastal rail route. Then, assuming rapid deployment of existing and near market technologies, speculative locomotive designs are proposed for both battery only and hydrogen-battery systems. Batteries were assumed as rack mounted systems and hydrogen assumed at 250 bar gaseous. The results showed that full recovery of dynamic braking required only a very small amount of storage to capture and allow re-use, requiring a battery of only 6% of the trip total of recovered energy. The haulage task was found to require traction energy of 10.7 MWh per locomotive but reduced to a net requirement of 7.6 MWh per locomotive with recovery of dynamic braking energy. The large mass of batteries needed for the operating trip, however, limits the practical operating range. The results showed that, although hydrogen storage and equipment occupy considerable space and the containment systems have large mass, the space and mass requirements for a hydrogen system in this case study could be as low as half that required for batteries, while higher pressure or cryogenic approaches to hydrogen storage will allow the scaling for longer range.
