“Feasibility of Hydrogen Fuel Cell Technology for Railway Intercity Services: A Case Study for the Piedmont in North Carolina,” Orwell Madovi, Andreas Hoffrichter, Nick Little, Shanelle Foster and Raphael Isaac, Railway Engineering Science, Volume 29, October 2021.
An Integrated Hybrid Train Simulator for intercity railway is used to evaluate the feasibility of various train and powertrain configurations. A case study of the Piedmont intercity service in North Carolina features six train configurations and powertrain options, and nine hydrogen supply options in addition to diesel. The results from the hydrail option suggest that a low- or zero-carbon hydrogen supply chain could be possible.
