Hydrogen is the simplest element on earth—it consists of only one proton and one electron—and it is an energy carrier, not an energy source. Hydrogen can store and deliver usable energy, but it doesn't typically exist by itself in nature and must be produced from compounds that contain it.

Hydrogen is an essential element that plays a crucial role in numerous industrial applications. In various chemical reactions, hydrogen acts as a source of reactive hydrogen atoms, which can facilitate the removal of oxygen from compounds or promote the conversion of undesirable chemicals into more valuable products. This attribute makes hydrogen an indispensable component in numerous chemical manufacturing processes, including the production of methanol, ammonia, and various synthetic materials.
