What are facts about Hydrogen Energy?
Hydrogen Energy Facts. Hydrogen is the most basic and most common element on Earth. Represented by the letter "H" on the periodic table, hydrogen is a gas that combines with oxygen to make water (H 2 O), and with carbon to form compounds such as methane and coal. Hydrogen is also a potent source of clean energy.
