A concept of electrified Steam Methane Reforming (eSMR) using reformer tubes is proposed as a cost-effective pathway for hydrogen decarbonization. The concept applies radiant heating elements to a gas-fired reformer, and a thermochemical model and techno-economic analysis demonstrate its superior performance compared to mainstream alternatives. Results show that reformer tube electrification is both economically viable and technically feasible, making it a promising solution for low-cost decarbonization of hydrogen production.
A concept for electrified Steam Methane Reforming (eSMR) based on reformer tubes is proposed as a pathway for hydrogen decarbonization. The proposed concept applies radiant heating elements to a conventional gas-fired reformer. A thermochemical model and a techno-economic framework are developed to evaluate process performance at various conditions and the economic potential of the proposed concept. A baseline scenario with feedstock and electricity priced respectively at $4/MMBtu and $0.04/kWh, and assuming 2% of fugitive methane emissions and 50 gCO2eq/kWh, results in an LCOH of $1.53/kgH2 and a decarbonization cost of $38/tonCO2. The techno-economic results demonstrate that the proposed eSMR process leads to lower LCOH than mainstream alternatives over a wide range of energy prices. The study shows that reformer tube electrification is both economically viable and technically feasible, and therefore has the potential to decarbonize hydrogen production at a low cost.
