      Hi dounia199! There are a couple of ways hydrogen is different to other fuels. Firstly, per kg of fuel, hydrogen releases lots more energy than most other fuels – that’s one of the reasons why we’re so interested in using it. The other advantage of using hydrogen is that using it as a fuel doesn’t release any carbon dioxide, a chemical which causes global warming. Most other fuels aren’t as good for the environment. Hope this answers your question 🙂
