“…This probably implies that reaction (R22) dominates cell performance. Promotion of reaction (R23) is expected to enhance cell performance, as shown by theoretical studies (Ni, 2013). This can be achieved by developing selective electrocatalysts for reaction (R23).…”

“…This concept, also called direct-biogas solid oxide fuel cell (DB-SOFC), offers several advantages in comparison to the previously discussed method of external reforming (Figure 5), has currently received much attention in both experimental (Goula et al, 2006;Yentekakis, 2006 FIGURE 5 | Schematic of the differences between external (A) and internal (B) reforming concepts for SOFC-added electrical power generation from biogas. Papadam et al, 2012;Takahashi et al, 2012;Lanzini et al, 2013;Ma et al, 2015; and references therein) and modeling studies (Lanzini et al, 2011;Ni, 2013;Janardhanan, 2015a,b). Most of these studies made use of Ni-based cermet anodes, doped with additives in some cases in order to prevent carbon deposition (e.g., Yentekakis, 2006;Ma et al, 2015;Niakolas et al, 2015).…”

Biogas is widely available as a product of anaerobic digestion of urban, industrial, animal and agricultural wastes. Its indigenous local-base production offers the promise of a dispersed renewable energy source that can significantly contribute to regional economic growth. Biogas composition typically consists of 35-75% methane, 25-65% carbon dioxide, 1-5% hydrogen along with minor quantities of water vapor, ammonia, hydrogen sulfide and halides. Current utilization for heating and lighting is inefficient and polluting, and, in the case of poor quality biogas (CH 4 /CO 2 < 1), exacerbated by detrimental venting to the atmosphere. Accordingly, innovative and efficient strategies for improving the management and utilization of biogas for the production of sustainable electrical power or high added-value chemicals are highly desirable. Utilization is the focus of the present review in which the scientific and technological basis underlying alternative routes to the efficient and eco-friendly exploitation of biogas are described and discussed. After concisely reviewing state-of-the-art purification and upgrading methods, in-depth consideration is given to the exploitation of biogas in the renewable energy, liquid fuels, transport and chemicals sectors along with an account of potential impediments to further progress.Keywords: biogas, upgrading, purification, utilization, SOFC, ethylene, reforming, siloxanes BIOGAS Efficient management of ever-increasing amounts of municipal, industrial and agricultural wastes in order to minimize their environmental impact is an urgent necessity. Biological treatment of wastes, which can be carried out either aerobically or anaerobically, is widely applied in this area. Due to their several advantages the anaerobic processes are to be preferred because they require considerably smaller installations, produce less sludge, operate at lower temperatures and are suited to periodic operation. Much more importantly, they generate biogas, which is an attractive potential source of renewable energy and/or added-value chemicals due to its high content of methane and CO 2 . Anaerobic digestion (AD) can proceed over a wide temperature range, from phychrophilic (ca. 10-20 • C) and mesophilic (ca. 20-45 • C) up to thermophilic (ca. 45-65 • C) and hyperthermophilic (ca. ∼70 • C) levels, by means of cooperation between anaerobes and facultative anaerobe microorganisms, which successively promote a sequence of hydrolysis-acidogenesis,

“…Furthermore, the costs of auxiliary components (e.g., transformers, exhaust-flow controllers, etc.) were estimated at 5% of the main equipment cost, i.e., $101,000, as the maintenance cost in China is relatively lower than that in some developed countries [19]. Therefore, the estimated total cost of SOFC-based subsystem was $2.121 million, and of the integrated system, $2.436 million.…”

Abstract:The building sector consumes a great deal of energy and generates organic waste, and thus has been a cause of considerable environmental concern. One distributed-energy technique, solid oxide fuel cell (SOFC)-based biogas-from-waste generation, has shown promise for waste treatment as well as energy saving in buildings. This study proposes a high-efficiency cooling, heating and electricity-generation system with an SOFC-absorption water-cooled tri-generation configuration. Operations data from a typical high-rise commercial building in Shanghai were analyzed as a case study of the proposed system's economic, environmental, and social feasibility in China. The results indicated that its economic performance was satisfactory, with a short payback period of less than one year if subsidized. Additionally, the system was found to achieve high efficiency: i.e., 85%, as compared to approximately 40% achieved by conventional combustion-powered systems. Finally, in terms of social feasibility, survey respondents not only expressed positive overall attitudes towards the application of the system, but also raised concerns about its long-term operating costs. Given that foreseeable technological advancements promise greater flexibility and reduced space requirements, these results imply that the proposed integrated SOFC multi-generation system will be well-suited to future infrastructure and building projects in China.

“…Note that the transfer coefficient applied in Eqs. (7)-(9) is set to be 0.5, which is a very typical value for SOFCs electrode [21,22]. The porosity is set as 0.3 according to experimental testing of an SOFC using similar fabrication techniques [23].…”
