When you burn hydrogen as fuel, you combine hydrogen and oxygen, resulting in some energy and some water.
Fun fact: using any hydrocarbon as fuel (methane, propane, gasoline/petrol, alcohol, wood, etc) results in water being produced, because the chemical reaction is combining oxygen with the fuel, and some of the hydrogen in the hydrocarbon reacts with some of the oxygen, resulting in water. Of course, plenty of other compounds are also produced, many of which are dangerous to health, but there’s water being produced too.
