“…The purchased equipment cost was calculated using an exponential scaling expression based on the cost and size data in the National Renewable Energy Laboratory report . The installed equipment cost, which includes additional costs required to install the equipment and make it operational (e.g., piping), and the total capital investment, which includes project contingency, were then estimated sequentially using a factored approach in which a multiplier is applied to the purchased equipment cost. − The capital recovery factor was used to extract the actually dissipated value (by depreciation) of the equipment for 1 year after the installed equipment cost, assuming an interest rate and equipment lifetime of 6% and 30 yr, respectively . The catalyst replacement cost was estimated considering the stability of catalysts in severe conditions with a high CO concentration.…”

A comparative study to obtain a cost-competitive catalyst was performed to produce hydrogen via the high temperature water gas shift (WGS) reaction using synthesis gas (syngas) derived from waste. First, several selected active metals on Nb−CeO 2 support and preparation methods were applied to prepare highly active and stable catalysts under severe reaction conditions. Various characterization methods were employed to understand the correlation between catalytic activity and physicochemical properties of the prepared catalysts. Among the Me−Nb−CeO 2 (Me = Co, Cu, Fe, and Zn) catalysts, Co−Nb− CeO 2 showed the highest activity at a high gas hourly space velocity of 315,282 mL•g −1 •h −1 (temperature = 500 °C, X CO ≈ 84%). This was attributed to the high Brunauer−Emmett−Teller surface area and oxygen storage capacity of the Co−Nb−CeO 2 catalyst. In addition, to investigate the effect of preparation method, various methods, including coprecipitation, incipient wetness impregnation, sol−gel, and hydrothermal methods, were applied for the synthesis of the Co−Nb−CeO 2 catalyst. The Co−Nb− CeO 2 catalyst prepared using the coprecipitation method exhibited high activity without significant deactivation for 60 h. This was attributed to the high oxygen storage capacity and intimate interaction between Co and the Nb−CeO 2 support. Finally, technoeconomic analysis and environmental impact assessment were performed for the Co−Nb−CeO 2 catalysts, prepared by different preparation methods to identify the most promising catalyst for the production of hydrogen using the syngas derived from waste. By comparison with a commercial catalyst, it was shown that Co−Nb−CeO 2 synthesized using coprecipitation is a promising, costeffective, and eco-friendly catalyst with high activity.

Steam methane reforming (SMR) process is regarded as a viable option to satisfy the growing demand for hydrogen, mainly because of its capability for the mass production of hydrogen and the maturity of the technology. In this study, an economically optimal process configuration of SMR is proposed by investigating six scenarios with different design and operating conditions, including CO2 emission permits and CO2 capture and sale. Of the six scenarios, the process configuration involving CO2 capture and sale is the most economical, with an H2 production cost of $1.80/kg-H2. A wide range of economic analyses is performed to identify the tradeoffs and cost drivers of the SMR process in the economically optimal scenario. Depending on the CO2 selling price and the CO2 capture cost, the economic feasibility of the SMR-based H2 production process can be further improved.
