“…Twenty of the seventy-five papers concentrate on economic aspects. Often, production costs are in the center of these ones (e.g., [31][32][33][34][35][36][37]). Other target figures/indicators used are fuel cell system costs [38,39], costs of electricity or energy [40][41][42][43][44], total product unit costs [45], capital costs [46], costs for fuels [47], the net present value (NPV) [48,49], or ownership costs [50].…”

“…Some authors apply specific equations and formulas for calculating the costs for hydrogen production [47] or for system and component costs [39,45]. For the determination of the total production costs, Ma et al use equations as well [37]. Like Chen and Melaina, these four papers perform a sensitivity analysis as well to address uncertainties in their We analyzed the papers regarding several aspects, especially their focus of evaluation (economic, ecological, and/or social) as well as the methods and target figures they used.…”

Enhancing the sustainability of activities is an undebatable need for decision makers regarding the economy as well as society. Fuel cells and their application in different areas, such as energy supply or mobility, are viewed as a promising means towards more sustainability. However, fuel cells as well as fuel-cell-based application systems cause a couple of possibly conflictive impacts in terms of ecological, economic, and social targets—their positive contribution to sustainability is not confident. Consequently, a significant assessment of sustainability is needed to enable a targeted development of fuel cells and their application systems, including the selection of alternative design variants. Furthermore, such assessment is necessary to provide evidence for the intended improvements and thereby contribute to market success and implementation of the systems. However, an overview of the existing methods for sustainability-related assessment of fuel cells and fuel-cell-based systems as well as the outcomes of the assessments does not exist. Therefore, a systematic literature review is conducted without restriction of fuel cell types and evaluation methods. Such a comprehensive overview does not yet exist to the best of the authors’ knowledge. With regard to the suggested or applied methods, the results show, amongst others, that the economic assessment does not refer to the methodical state-of-art, the social dimension is neglected, and an overall assessment of sustainability, aggregating all three dimensions, is not conducted. Due to the variety of analyzed objects as well as applied methods, the outcomes of the studies provide not more than scattered knowledge about the relevance of components and the advantageousness of fuel cells, their variants, and their application systems regarding sustainability. To contribute to avoiding methodological deficiencies, a procedure model for an integrated assessment is presented.

“…The last step is distillation where the purification of the fermentation broth occurs. Distillation is an effective and favorable separation technique as the preferred choice for industrial application due to high alcohol recovery of 99.5% v/v purity, sufficient energy efficiency at moderate feed concentrations, and the ability to simulate the process using process simulation software which makes the integration of mass and energy in other processes easier to accomplish [131][132][133]. All formed byproducts and other impurities are removed during this process, and only imprints remain.…”

On the basis of its properties, ethanol has been identified as the most used biofuel because of its remarkable contribution in reducing emissions of carbon dioxide which are the source of greenhouse gas and prompt climate change or global warming worldwide. The use of ethanol as a new source of biofuel reduces the dependence on conventional gasoline, thus showing a decreasing pattern of production every year. This article contains an updated overview of recent developments in the new technologies and operations in ethanol production, such as the hydration of ethylene, biomass residue, lignocellulosic materials, fermentation, electrochemical reduction, dimethyl ether, reverse water gas shift, and catalytic hydrogenation reaction. An improvement in the catalytic hydrogenation of CO2 into ethanol needs extensive research to address the properties that need modification, such as physical, catalytic, and chemical upgrading. Overall, this assessment provides basic suggestions for improving ethanol synthesis as a source of renewable energy in the future.
