With an increasing interest in hydrogen as an eco-friendly energy carrier, techno-economic analysis for hydrogen production is very essential. Among the various hydrogen production methods such as methane steam reforming (MSR), coal gasification, oil-based hydrogen production, and water electrolysis, MSR is chosen in this paper because it is a commercialized production method accounting for about 48% of global hydrogen production. Comparative studies for MSR in a conventional packed-bed reactor and a membrane reactor equipped with a hydrogen separation membrane showed the improved reactant conversions and product yields in a membrane reactor because of Le Chatelier's principle. In addition, economic analysis was carried out to assess its economic feasibility through itemized cost estimation based on capital and operating costs, sensitivity analysis, and profitability analysis using cash flow diagram. |
