This work presents a techno-economic analysis of multiple direct hydrogen production technologies using different blends of Arabian crude oil and natural gas as feedstock: Auto thermal reforming, steam reforming, and combined reforming technologies are thermodynamically and technically evaluated through development of process flowsheets. Comparative analysis indicates that combined reforming using Arabian light crude oil achieves a 22.69 % of hydrogen recovery with carbon capture, which is higher than auto thermal reforming and steam reforming by 0.7 %. At the same time, auto thermal reforming achieves a 26.70 % of hydrogen recovery without carbon capture, which is higher than steam reforming and combined reforming by 4 %. Arabian heavy, medium, light, and extra light are evaluated using auto thermal reforming technology to estimate hydrogen recovery values. A wide range of crude oil and natural gas prices are included in the analysis to calculate hydrogen production cost. With crude oil price at 90 USD/bb, the hydrogen production cost is 2.9 USD/kg, and natural gas prices at 30 USD/MMBtu (Europe), 20 USD/MMBtu (Japan), and 2.5 USD/MMBtu (GCC region), the hydrogen production cost is 4.5, 3.0, and 0.4 USD/kg respectively.
