"The Bloom systems run on natural gas. "
"The Bloom systems run on natural gas. They strip the hydrogen out of the natural gas and that becomes the feedstock for the fuel cells. So, instead or burning the natural gas to spin a turbine to produce electricity, the hydrogen flows through the fuel cells and the chemical reaction of it passing through the cells produces electricity."
What percentage of the "natural gas" is Hydrogen? And what happens to all the not-Hydrogen? Or is there some sort of catalysis going on that also takes the Hydrogen from the Methane and other components? And if the latter is the case, what happens to the "waste" product? Is it mostly a nearly pure Carbon "soot"?
