Hydrogen storage and supply for vehicles

Hydrogen vehicle storage and supply systems typically use high‑pressure composite tanks (often 350 bar or 700 bar) along with regulators, valves, piping, and safety sensors to deliver hydrogen fuel to either a fuel cell stack or a combustion engine.[11][15] For motorsport and demonstrator applications such as at Le Mans, dedicated refueling infrastructure and safety procedures are implemented to manage leak detection, ventilation, and emergency shut‑down given hydrogen’s low ignition energy and tendency to disperse rapidly.[8][11]
