“…However, they are best fitted to large scale applications. For instance, net plant efficiency of 46.4% compared to those of the GE Energy and Shell Convective plants (39.2% and 42.0%, respectively), were reported by Esmaili et al [28].…”

A bioethanol reforming system, capable of converting a diluted water-ethanol mixture into hydrogen, is sized and set up to produce 5 kW of electric power via a polymer electrolyte membrane fuel cells (PEMFC). A part of the produced hydrogen supplies heat for the reforming reaction without impairing the power generation, then no additional fuel is required. According to the different configurations of the control variables, the heat released from the system is distributed between two different temperature ranges and coupled to a standard house-scale combined heat and power (CHP) cogeneration apparatus. Hot water can be produced continuously at a high enough temperature to cover the need of a F-class home in the moderately cold Northern Italy winter climate. With a micro-accumulation solution and a careful choice of the set-points, also the sanitary hot water demand (DHW) of a 4-members family might be fulfilled with 2-3 daily cycles of the same system.

“…Referring to the economic sensitivity analysis of the power plants with CCS [4,47], a sensitivity analysis was performed by varying main economic parameters leads, e.g., biomass price, electricity price, hydrogen price yearly running hours, and capital expenditure (fixed capital cost). The economic parameters are identified by variation from −50% to 50%.…”

“…The amount of coal consumed for hydrogen production is 107 Mt (2% of global coal use), and natural gas accounts for 205 Gm 3 (6% of global natural gas), generating 830 Mt CO 2 emissions, which are 2% of total global emissions [3]. Hence, an increase in hydrogen demand would lead to additional CO 2 emissions; however, without carbon capture and storage (CCS), the existing technology infrastructure cannot meet the 2 • C Paris Agreement goal for climate change [1,2,4].…”

Techno-Economic Analysis of Hydrogen and Electricity Production by Biomass Calcium Looping Gasification

Combined cycle, biomass calcium looping gasification is proposed for a hydrogen and electricity production (CLGCC–H) system. The process simulation Aspen Plus is used to conduct techno-economic analysis of the CLGCC–H system. The appropriate detailed models are set up for the proposed system. Furthermore, a dual fluidized bed is optimized for hydrogen production at 700 °C and 12 bar. For comparison, calcium looping gasification with the combined cycle for electricity (CLGCC) is selected with the same parameters. The system exergy and energy efficiency of CLGCC–H reached as high as 60.79% and 64.75%, while the CLGCC system had 51.22% and 54.19%. The IRR and payback period of the CLGCC–H system, based on economic data, are calculated as 17.43% and 7.35 years, respectively. However, the CLGCC system has an IRR of 11.45% and a payback period of 9.99 years, respectively. The results show that the calcium looping gasification-based hydrogen and electricity coproduction system has a promising market prospect in the near future.

“…Studies focusing on the economic assessment of biomass gasification have also recently been published (Esmaili et al, 2016;Ptasinski 2016;Rahimi et al, 2020). For example, Rahimi et al (2020) developed a comprehensive software program to simulate biomass gasification, which utilized an experimental setup to calibrate the simulation results with appropriate modeling coefficients.…”

Comparative Techno-Economic and Exergetic Analysis of Circulating and Dual Bed Biomass Gasification Systems

In this work, the techno-economic and exergy analyses of two gasification technologies with integration into heat and power combined cycles are presented: i). Circulating fluidized bed (CFB) and ii). Dual fluidized bed (DFB) systems. As feedstock, lignocellulosic biomass (sugarcane bagasse, SCB) was considered. The gasification process of the fluidized-bed systems (circulating and dual bed) and the syngas conversion were performed using Aspen Plus® software. The process design includes biomass drying and gasification, syngas cleaning, combustion, power generation, and heat recovery. The SCB-DFB system has the lowest irreversibility rate and, as a result, the highest overall performance and power generation (achieving 32% in the gasification system and 53% of exergy efficiency when coupled with the combined cycle). From the techno-economic assessment, the SCB-DFB system has the lowest total production costs per unit of energy. Hence, the dual fluidized bed systems could be a more competitive technology for the agro-industrial sector to generate power from lignocellulosic materials.
