Emission regulations for ships are forcing ship-owners and shipyards to drastically reduce harmful species for the Emission Control Areas (ECA) along the US coast, Baltic Sea and North Sea. SOFC systems are seen as most efficient and clean alternative to conventional diesel engines. A diesel based SOFC demonstrator is developed with a rated power of around 50 kW. It consists of 2 submodules supplying each 27 kW gross power. The key feature of the process is the adiabatic prereforming process that allows us to handle the diesel without any deep desulphurization technologies. Adiabatic prereforming of diesel is one of the most efficient types of fuel processing for SOFC systems. The feasibility of adiabatic prereforming of commercial ultra-low sulphur diesel has successfully been tested with one of Haldor Topsoe's catalyst. The demonstrator was started on commercial road diesel containing 11.3 ppm_wt sulphur, 6.2%_vol FAME and 24%_wt aromatics. An electrical gross efficiency of 55% and fuel utilization of 73% could be demonstrated already during the first hours of operation. |
