Estimating The Carbon Footprint Of Hydrogen Production
Hydrogen is the lightest and most abundant element in the universe. It can be used as a source of power, and it is an important feed stock for many petrochemical processes.
When hydrogen is combusted, it forms water. Therefore, hydrogen can be used as a low-carbon fuel source. Hydrogen can be combusted directly, or it can be used in a fuel cell to produce electricity.
Since hydrogen produces minimal pollutants when combusted, it is envisioned by many as a core component of a cleaner energy future. President George W. Bush touted the potential for a "hydrogen economy" in his 2003 State of the Union address. Billions of dollars have been invested in the attempt to realize this vision.
