depends what it is being used for. if it is being used for nucleur fusion it isnt because the hydrogen is turned into helium and cannot be returned. but with burning it can be renewable since it can be retrieved from the water. however all fuels are eventually non-renewable since the sun will eventually run out of fuel. it depends what is considered renewable.

Hydrogen isn't precisely renewable. that's by a ways the most plentiful ingredient interior the universe, yet practically each of the hydrogen life isn't in a form usable as organic hydrogen (H2) gas. that's both targeted in stars or interstellar clouds present procedure nuclear fusion and accordingly thoroughly inaccessible to us in the international, or that's right here in the international yet in chemical substances (jointly with water, organic gas, oil, and organic and organic remember). The combustion of hydrogen yields warmth (that can change into usable capacity) and water (the in problem-free words waste product or emission of burning hydrogen): 2H2 + O2 --> 2H2O + warmth The reaction would nicely be reversed to type hydrogen and oxygen from water and warmth, yet you'll opt to enter the same quantity of capacity to split the water molecules into hydrogen and oxygen as you would by burning the hydrogen with oxygen gas. And no procedure is extremely 100% capacity-effective, so at the same time as we may be able to create hydrogen gas by electrolysis (splitting water into oxygen and hydrogen) we are able to interior the technique finally end up utilizing more suitable capacity than we receives decrease back from burning the hydrogen created by this procedure. So for all useful applications, that's no longer renewable. Hydrogen gas is likewise created from reactions that contain the breaking down of oil and organic gas, which obviously aren't any more considered renewable. the in problem-free words thanks to really "create" hydrogen is by nuclear techniques, breaking down heavier factors atomically into smaller factors. That consists of with it numerous different complications jointly with lots of nuclear waste and putting apart the great things (hydrogen) from the undesirable stuff, and the devastating consequences of any significant twist of destiny.

sure, when it's burned it just turns to water. Unfortunately, it costs energy to extract the hydrogen from water. It's not found as a pure gas and it's very difficult to store.

No. If you are burning it then it is gone. You can't retrieve H2 from H2O without expending at least as much energy as you release when you burn it (otherwise you would be violating the law of conservation of energy). It is environmentally freindly because burning it does not release CO2.
