Hydrogen fuel is a zero-emission fuel when hydrogen is burned with oxygen (if one considers water not as an emission) or used in a contained cell also capable of 'reversing' the reaction if needed.
Description
Hydrogen is often used as fuel in electrochemical cells, or combustion in internal engines, to power vehicles and electric devices.
It is also used in the propulsion of spacecraft and might potentially be mass-produced and commercialized for passenger vehicles and aircraft.
Energy carrier, not energy resource
Since there is very little free hydrogen gas, hydrogen is in practice only an energy carrier, like electricity, not an energy resource.
Hydrogen gas must be produced, and that production always requires more energy than can be retrieved from the gas as a fuel later on.
