“…SOFC operates at high-temperature, being a good option when energy systems are designed via biomass gasification, due to similar high operational temperature of SOFC and biomass gasification process. SOFC also produces byproducts like heat, which is proper for cogeneration facilities [60].…”

“…The SOFC has been considered a suitable option for efficient integration with other energy conversion technologies namely, gas turbine (GT), steam turbine (ST), organic Rankine cycle (ORC), Stirling engine, etc. [60]. Most of the studies are based in modeling results and present the combination SOFC-GT (gas turbine) as the main option to improve system performance [61,80,84,90], however more complex solutions are also presented but most of them including the GT [60,79,91].…”

“…A HRSG was also included in the cogeneration system proposed by Roy et al [60], but an externally fired gas turbine (EFGT) was considered instead of the MGT. These authors performed modeling and analysis of an integrated cogeneration system for heat and power generation, which included a biomass gasifier, a SOFC module, an externally fired gas turbine (EFGT) block and a HRSG.…”

This paper reviews the most recent information about the main operations to produce energy from carbonaceous materials, namely biomass and wastes through the integration of gasification, syngas cleaning and solid oxide fuel cells (SOFCs), which have shown to be a good option for combined heat and power (CHP) production, due to high efficiency and low environmental impact. However, some challenges still need to be overcome, mainly when mixed feedstocks with high contents of hazardous contaminants are used, thus syngas cleaning and conditioning is of major importance. Another drawback is SOFC operation, hence new materials especially for the anode has been proposed and tested. An overall process to produce CHP by gasification integration with SOFC is proposed.

“…are very limited contributions to justifying and comparing different biomass to bioenergy conversion techniques from technical, environmental, and economic aspects. In the subject of biomass gasification, several studies carried out thermoeconomic assessment of gasification systems in integration with other energy generation technologies such as Fuel Cell (FC) [6,7], Stirling engines [8,9], and micro-turbines [10,11]. Often, optimizing the Levelised Cost of Energy (LCOE) and exergy efficiency, by performing sensitivity analyses on several thermodynamic parameters, was the main objective in these studies.…”

Biomass is one of the most versatile sustainable energy sources. This versatility allows utilization of different biomass feedstock using a verity of conversion techniques. Often, a biomass‐to‐bioenergy conversion method is selected depending on the application, end‐use product, and the type of feedstock. In many applications such as residential energy supply, it is possible to select amongst various technologies. Although, there exist several challenges such as cost‐effectiveness and sustainability that constrains bioenergy development. To this end, this research elaborates on the impacts of different conversion methods on techno‐economic performance of bioenergy systems for residential energy supply. In this context, Organic Rankine Cycle based on direct combustion, and Dual Fluidized‐Bed technology based on gasification were selected for that purpose. A techno‐economic comparative analysis illustrates that the primary product of the system and fuel cost are the two most important factors in feasibility assessment. The negative impact of feedstock price was more severe on the Organic Rankine Cycle. For wood chips prices below 55$/t, Organic Rankine Cycle could be the better option due to lower capital and maintenance costs. In contrast, Dual Fluidized‐Bed could better tolerate the variation of feedstock price; offering 8% lower cost of energy at 65$/t wood chips.

A detailed technoeconomic analysis of a standalone steam cycle integrated with molten carbonate fuel cell and an organic Rankine cycle is presented herein. The modeling and thermodynamic analysis of the proposed plant is performed using a commercially available software tool called Cycle Tempo. The response surface methodology tool is employed to develop regression models to predict the plant's energy, exergy efficiencies, and levelized cost of electricity (LCOE) for varying independent factors: fuel utilization factor (uf) CO2 utilization factor (ϕ), and current density (i) of the fuel cell. The response surfaces developed from the models are used to conduct the parametric analyses on the plant. The desirability test performed for multiobjective optimization has shown the optimum plant configuration, with higher energy, exergy efficiencies, and a lower LCOE is obtained for uf = 0.85, ϕ = 60%, and i = 1000 A m−2 With an intent to reduce CO2 emissions, monoethanolamine‐based carbon capture system is implemented to the plant configuration, that exhibits maximum energy efficiency for ϕ = 90%, and results in an LCOE of 6.53 Rs kWh−1.
