- Natural Gas
A gas mixture that occurs naturally in underground deposits. It is composed primarily of methane and may contain other hydrocarbons, carbon dioxide, and hydrogen sulfide. Commonly employed as a fuel for electricity generation, it is also used for space heating, industrial processes, and as a starting material for the manufacture of chemicals and other products.
