Decarbonized hydrogen and electricity from natural gas

Heat and mass balances are evaluated by a model accounting for the constraints posed by commercial technology, as well as the effects of scale. Results show that, from a performance standpoint, the technologies of choice for the production of de-carbonized hydrogen from NG are FTR with SC or ATR with CC. When operated at high steam-to-carbon ratios, the latter reach CO2 emissions chargeable to hydrogen of 10-11 kg of CO2 per GJLHV-less than 20% of NG-with an equivalent efficiency of hydrogen production in excess of 77%.
