“…The operating temperatures of biomass gasification plants and SOFCs match perfectly. In the last few years, many studies have been carried out to determine the optimal operating conditions, the performance, and the potentials and limitations of various integrated power plant coupling gasifier and SOFC [4][5][6][7][8][9][10][11][12][13][14][15][16].…”

An innovative process based on hydrothermal carbonization, gasification, and solid oxide fuel cells (SOFCs) technologies was developed using a commercial process simulation software called ASPEN Plus. The object of this work is to study plant efficiency under various operating conditions. The hydrothermal pre-treatment (HTC) at 200 and 250 °C was modelled as a black box based on the experimental results. The gasifier was modelled as a single reactor vessel with both the fluidized bed steam gasification of solid fuel and the hot gas cleaning system. The SOFC was modelled as a simple grey box with the ASPEN Plus blocks. The effect of HTC temperature and steam/carbon (S/C) ratio on the syngas composition and yield and plant efficiency was studied. The results show that the gasification of hydrochar obtained at 200 °C with S/C ratio of 0.6 gives the best results, namely an energy output of SOFC equal to 1.81 kW/kgBiomass, and overall process efficiency of 36%.

“…Syngas may directly feed to Solid oxide fuel cell (SOFC) units, or be further purified by removing CO to feed proton exchange membrane fuel cell (PEMFC). In fact, hydrogen as a strategic energy vector could be derived from syngas which is much more favourable compared to fossil fuels: one kg of hydrogen produces an energy equivalent to that produced by 2.63 kg of gasoline [17][18].…”

“…This possibility has been described theoretically [3][4][5][6][7][8][9] , while experimental investigations are rare. [10,11] The option is not only limited by technical but also by economical obstacles. Another possible route to produce biogas is the anaerobic digestion of biomass.…”

Oxidative Dry‐Reforming of Biogas: Reactor Design and SOFC System Integration

et al. 2013

Biogas is an attractive fuel for solid oxide fuel cell applications because of the high CO2 content. Its composition allows a high electrical efficiency without adding external water to the system. Because of the CO2 reforming reaction only a very small amount of air is needed for partial oxidation, which is why the process could be called oxidative dry‐reforming. Herein, this concept is demonstrated by a thermodynamic analysis of the process and experimental system and component results. In order to realize a high yield of electrical power from the SOFC stack, a large flow of chemical energy into the stack is needed. To achieve this goal the efficiency of the reforming process is essential. With optimized reforming conditions it is possible to increase the chemical energy content of the fuel by adding an ample amount of heat to the reforming step. To achieve this in practice, the necessary heat flow to the reformer has to be calculated for a given operating temperature. Based on these thermodynamic calculations a reactor was built and tested. After successful laboratory tests the reactor was integrated into an SOFC system, where the necessary heat for the reforming step was supplied by the afterburner. The results of the component tests were verified under system conditions. Based on this system concept a high value for the electrical efficiency (ηel>0.5) of the system was achieved.
