From Wikipedia: Hydrogen is a chemical element with chemical symbol H and atomic number 1. With an atomic weight of 1.00794 u, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the universe, constituting roughly 75% of all baryonic mass.
Hydrogen provides a unique opportunity to reliably generate power with zero on-site emissions of pollutants or greenhouse gases.
Hydrogen releases energy when it bonds with oxygen. Through the use of a Hydrogen Fuel Cell this can be achieved through a reaction of hydrogen by an electrochemical reaction (known as electrolysis) in a fuel cell to produce electricity with the only emission being pure water H2O.
Globally the use of Hydrogen is involved in many new and innovative projects that stand to change the future of power production for domestic, commercial and industrial applications.
