Hydrogen, an energy source to replace fossil fuels, has been produced mainly through steam methane reforming (SMR) because of its high efficiency. However, SMR-based hydrogen production emits a large quantity of carbon dioxide due to steam injection. In this study, the process for carbon neutral hydrogen production via catalytic pyrolysis of methane (CPM) was developed and analyzed from economic and environmental perspectives. By using CPM, hydrogen production is possible to be produced via catalytic decomposition of methane at high temperature without emission of carbon dioxide. Our techno-economic analysis reveals that the levelized cost of hydrogen cost was determined to be $3,635/ton-H2, which could be further decreased to $1,750/ton-H2 when renewable energy-based surplus electricity was adjusted. Moreover, we quantified the indirect environmental impact via life-cycle assessment. |
