Abstract: A solid oxide fuel cell power generation system's entire output is made up of three streams: water, sequestered carbon dioxide provided into a storage tank, and carbon dioxide depleted air. Thus, the system generates electricity from a hydrocarbon fuel, while outputting substantially no pollutants into the atmosphere and cleaning the air by removing carbon dioxide from the air exhaust stream. Thus, the system outputs cleaner air than it takes in without releasing pollutants into the atmosphere, while generating electricity from a readily available hydrocarbon fuel, such as natural gas.
