Water enriched in molecules that include deuterium instead of normal hydrogen is called Elemental hydrogen from solar, biological, or electrical sources requires more energy to make than is obtained by burning it, so in these cases hydrogen functions as an energy carrier, like a battery
Hydrogen forms a vast array of compounds with called the , and an even vaster array with that, because of their general association with living things, are called H 2 is also used as a of metallic
