Hydrogen Basics | NREL
WEBHydrogen as an Energy Carrier. Because hydrogen typically does not exist freely in nature and is produced from other sources of energy, it is known as an energy carrier.It is a clean-burning fuel, and when combined with oxygen in a fuel cell, hydrogen produces heat and electricity with only water vapor as a by-product.
