Japan has introduced hydrogen fuel-cell passenger trains that emit only water vapor during operation. The trains generate electricity onboard by combining hydrogen with oxygen, offering a zero-emission alternative to diesel on non-electrified rail lines. Hydrogen trains could play a key role in decarbonizing regional rail networks worldwide. Important Details: • Powered by hydrogen fuel cells • Emits only water vapor • Replaces diesel on non-electrified lines • Quiet and low-maintenance operatio
