Is there a hydrogen engine?

Why are hydrogen engines a bad idea?

Can you run an engine on hydrogen?

Hydrogen has a wide flammability range in comparison with all other fuels. As a result, hydrogen can be combusted in an internal combustion engine over a wide range of fuel-air mix- tures. A significant advantage of this is that hydrogen can run on a lean mixture.

Can I make my own hydrogen fuel?

It’s easy to make hydrogen gas at home or in a lab using common chemicals and everyday materials. Once you have the gas, you can use it for a variety of interesting science projects. Of course, you’re not “making” hydrogen, since it’s an element. It is produced by chemical reactions that release it.
