Sources of sulfur dioxide pollution In 1963, more than 23 million tons of sulfur dioxide were discharged into the atmosphere of the United States. The fossil-fueled power plant is the chief contributor to sulfur dioxide emissions and accounts for over 40% of the total emission.
The main use of hydrogen is to remove the sulfur that occurs naturally in fuels, a process that improves air quality. Sources of fossil energies such as crude oil naturally contain sulfur. The combustion of fuels containing sulfur produces sulfur oxides: SOx. These irritating gases cause a number of serious respiratory ailments.
