Hydrailとは 意味・読み方・使い方

Hydrail is the generic term denoting all forms of rail vehicles, large or small, which use on-board hydrogen as a source of energy to power the traction motors, or the auxiliaries, or both. Hydrail vehicles convert the chemical energy of hydrogen to mechanical energy either by burning hydrogen like in a hydrogen internal combustion engine vehicle, or by reacting hydrogen with oxygen in a fuel cell to run electric motors. Widespread use of hydrogen for fueling rail transportation is a key element of the proposed hydrogen economy. The term is now used extensively by research scholars and technicians around the world. However, no hydrail rail systems are currently in public use.
