제목 MCFC R&D activities in Italy: focus on Non-conventional waste-derived fuels for Molten Carbonate Fuel Cell
초록 One possible way to contribute in reducing fossil fuel demand/dependency is the use of alternative or non-conventional fuels, derived from waste or biomass. These fuels are generally poor in energy content, which imposes localized deployment and maximum efficiency in their utilization. In the effort to maximize the energetic yield from these alternative sources the coupling of MCFCs to the fuel gas produced from these sources is an attractive option. Combining these resources with MCFCs would provide a significant contribution to environmentally friendly, efficient energy use. Replacement of conventional technologies (ICE, GT) with MCFCs would allow a more efficient use of bio-fuels but, more significantly, would reduce NOx and SOx to very low levels and increase CO2 benefits. The crucial link between anaerobic digestion and MCFC is formed by the gas clean-up step to trap trace elements, originate from the organic nature of the feedstock, that have detrimental effects on fuel cell performance and durability. The most common contaminant contained in the biogas is hydrogen sulphide (H2S), relevant for harmful effects, both on the fuel cell electrodes as on the reforming catalysts. For this reason a quite large part of the current studies of “MCFC community” is dedicated to the particular effects of H2S on the MCFC anode. The objectives being the identification of the true, effective tolerance limits of current MCFC materials.
MCFC R&D activities in Italy will be presented focusing the problems related to the coupling of MCFC to an anaerobic digestion process of organic residues. In particular experimental investigation of MCFC running on simulated reformed biogas from anaerobic digestion and the effects of H2S and impurities on Ni-NiAl Anode are highlighted.
Finally a technical-economical analysis will be illustrated, considering the use of biogas in a 1.4 MW MCFC plant, in order to identify the most important economic parameters that affect the use of biogas in MCFC.
