Hydrogen on-board storage options for rail vehicles are in the focus of the paper of Mathias Böhm. It focusses on the comparison of current implementation projects in hydrogen powered trains.
The paper of Markus Kordel discusses two innovative technologies to reduce energy demand for Air-Conditioning in hydrogen fuel cell rolling stock: The hydrogen powered air-conditioning (HyPAC) utilizes the pressure work between tank and fuel cell; the absorption refrigerator uses the waste heat from the fuel cell.
