(IN BRIEF) Ten Spanish companies are joining forces for the groundbreaking Hympulso project, aiming to develop a renewable hydrogen fuel cell-based propulsion system for a high-speed train. Led by Talgo, the …
A hydrogen rail powertrain was conceptualised and consisted of three different subsystems of the FC, battery, and hydrogen storage systems . A backward design approach is presented to evaluate the power demand according to a "route simulation data" method. The powertrain components are then conceptually sized based on the determined duty cycle.
