Hydrogen is the most abundant element in the universe and is the lightest of all elements and gases. In recent years, hydrogen has come to the forefront as an alternative, environmentally, friendly fuel. As an energy carrier, hydrogen provides many advantages versus other alternatives, particularly when used in a fuel cell.
Hydrogen is found in nature in combination with other elements. Natural gas (methane) and various renewable resources contain hydrogen and are the feedstocks for production of this molecule around the world.
