Hydrogen is colorless, odorless, and gaseous, element When Hydrogen is subject to a pressure 500,000 times greater than that of the earth's atmosphere, hydrogen becomes a solid with metallic properties. About 7.8 million metric tons of hydrogen are produced in the United States today, enough to power 20-30 million cars or 5-8 million homes.
