✦ Synopsis
This paper investigates various usages of natural gas (NG) as an energy source for different hydrogen production technologies. A comparison is made between the different methods of hydrogen production, based on the total amount of natural gas needed to produce a specific quantity of hydrogen, carbon dioxide emissions per mole of hydrogen produced, water requirements per mole of hydrogen produced, and a cost sensitivity analysis that takes into account the fuel cost, carbon dioxide capture cost and a carbon tax. The methods examined are the copperechlorine (CueCl) thermochemical cycle, steam methane reforming (SMR) and a modified sulfureiodine (SeI) thermochemical cycle. Also, an integrated CueCl/SMR plant is examined to show the unique advantages of modifying existing SMR plants with new hydrogen production technology. The analysis shows that the thermochemical CueCl cycle out-performs the other conventional methods with respect to fuel requirements, carbon dioxide emissions and total cost of production.
