Hydrogen Energy Overview
Hydrogen is a common element found in all fossil fuels and all organic matter. In its pure molecular form, H2, hydrogen is a colorless, odorless, nontoxic gas. Like oil and natural gas, hydrogen can be transported via pipeline or shipped in containers. When burned or used to power a fuel cell, hydrogen produces zero emissions besides water vapor. This makes it the ultimate clean fuel.
Hydrogen is the lightest gas and also the most energy-dense fuel per mass. One pound of hydrogen holds 52,000 Btu, three times the energy of a pound of gasoline. While hydrogen gas does not occur naturally on earth, it is easily produced in a variety of ways (link to “Hydrogen Production”).
For nearly all of history, humans have used hydrocarbons for fuel. Hydrocarbons are molecules containing primarily carbon and hydrogen. Coal, oil, and natural gas are all hydrocarbons. When burned, hydrocarbons produce water and carbon dioxide. More carbon-intensive fuels produce more carbon dioxide pollution. As a carbon-free fuel, hydrogen can end our age-old reliance on dirty hydrocarbons. This is one of many benefits of hydrogen energy.
Compare the carbon content in different fuels. More carbon equals more carbon dioxide emissions:
