WHAT IS THE COST PER LITER OF SULFUR GENERATED HYDROGEN?
If it takes 20 kilowatt hours of electricity to recycle the aluminum necessary to generate 1 kilogram of hydrogen and we can buy the electricity at ten cents per kilowatt hour, the cost to refine the aluminum is $2.00. Sulfur historically trades for 50 to 100 dollars per ton. At 100 dollars per ton, one kilogram of sulfur costs ten cents. If the reaction requires 3 kilograms of sulfur to produce a kilogram of hydrogen, the cost of the sulfur would be 30 cents. Thus, the total cost for the materials is $2.30.
