“…The studies conducted on MCFC integrated energy systems have shown that MCFC offers the technology of producing H 2 simultaneous to power generation and CO 2 capture process, which is demonstrated by the work of Barkoltz et al [ 15 ] In this study, the extent of H 2 synthesis is governed by a factor known as fuel utilization factor, which has an inverse proportionality effect on H 2 availability from the fuel cell at the anode outlet. The focus of this work is over the natural gas combined cycles, and as such the anode inlet is fed with syngas obtained from methane steam reforming.…”

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.

“…Therefore, this technology cannot be used, as the objective is to achieve carbon neutrality by 2050. However, unless a CO 2 capture device-which can produce hydrogen (H 2 ) through a transformation process that can be reused in the system [67]-is integrated into MCFCs, the system will remain bulky and tedious to model, and it will suffer from a significant increase in system costs. PEMFCs, SOFCs, and PAFCs are also suitable for large-scale electricity production.…”

To achieve a more ecologically friendly energy transition by the year 2050 under the European “green” accord, hydrogen has recently gained significant scientific interest due to its efficiency as an energy carrier. This paper focuses on large-scale hydrogen production systems based on marine renewable-energy-based wind turbines and tidal turbines. The paper reviews the different technologies of hydrogen production using water electrolyzers, energy storage unit base hydrogen vectors, and fuel cells (FC). The focus is on large-scale hydrogen production systems using marine renewable energies. This study compares electrolyzers, energy storage units, and FC technologies, with the main factors considered being cost, sustainability, and efficiency. Furthermore, a review of aging models of electrolyzers and FCs based on electrical circuit models is drawn from the literature and presented, including characterization methods of the model components and the parameters extraction methods, using a dynamic current profile. In addition, industrial projects for producing hydrogen from renewable energies that have already been completed or are now in progress are examined. The paper is concluded through a summary of recent hydrogen production and energy storage advances, as well as some applications. Perspectives on enhancing the sustainability and efficiency of hydrogen production systems are also proposed and discussed. This paper provides a review of behavioral aging models of electrolyzers and FCs when integrated into hydrogen production systems, as this is crucial for their successful deployment in an ever-changing energy context. We also review the EU’s potential for renewable energy analysis. In summary, this study provides valuable information for research and industry stakeholders aiming to promote a sustainable and environmentally friendly energy transition.

“…Several advantages account for the widespread use of MCFCs: they are highly efficient (>60%) (66), tolerant to impurities, can use a variety of fuels, and can be integrated to form combined heat and power cogeneration systems (59,62,63). Additionally, MCFCs offer the potential for carbon capture because they take in CO2 as an oxidant for operation (67)(68)(69)(70)(71). In this manner, the MCFC can be used to filter out CO2 from exhaust gases and produce electricity as a by-product.…”

With CO2, nitrous oxides, and methane emissions data across the African continent, this review paper quantitatively describes the health, environmental, and mortality (expressed as avoidable deaths in thousands per year) effects that the combustion of fossil fuels generates. As a solution, this research study goes further to describe, with visual aids, the technology of fuel cells, their attractive green value, the types of fuel cells including low-temperature and high-temperature fuel cells (LTFC & HTFC) that enable different applications, as well as their levels of commercialization readiness.
