Hydrogen burns to make clean water. Everything else that burns ends up with pollutants.

Hydrogen is special because it is one of two elements with only one orbital shell for electrons. Helium, which is the other element, has electrons in this shell, and is perfectly happy to remain that way. That means that hydrogen can participate in chemical reactions but helium can't. Furthermore, although hydrogen typically loses that electron and acquires a positive charge in the process, it can gain a second electron and become negatively charged. Sometimes a positively charged hydrogen ion is called proton.

The lightest and most abundant element. A hydrogen atom consists of one proton and one electron. A hydrogen nucleus is just a single proton. Hydrogen composes about 75 percent of the Sun but only a tiny fraction of the Earth.

it only has 1 electron in its first shell, which makes it very reactive.

It's lighter than air and it burns.

It is the basic element for all that is!
