BIO-HYDROGEN aims at the development of a cost effective biogas reforming system (10 kW hydrogen) for decentralised application with biogas from agricultural wastes, municipal waste water treatment plants and landfills. Main objective is the development of a reforming process with a better compatibility with biogas and hence shows an improved efficiency. The improvement of the heat and steam management for CO2 containing gas will be targeted with the aid of simulation and modelling. Further the biogas upgrading will be performed by means of state-of-the-art technologies for desulphurisation and by a biofilter for the removal of siloxanes. Latter is of great importance due to the fact that a cost effective technology is currently not available. Within this project laboratory results from a biofilter for siloxane removal will be upscaled to a pilot plant level showing a capacity of 2 m3/h biogas.These ambitious aims will be achieved by a well balanced international consortium containing the necessary critical mass. SME partner BESEL and RTD partner UNI DUISBURG will be jointly responsible for the development of the reforming unit (including the shift reactor). SME partner SCHMACK and RTD partner PROFACTOR will develop a biofilter unit for siloxane removal based on results from European research projects AMONCO and PROBAT (both coordinated by PROFACTOR within FP5).UNI NITRA will give support in the lab test phase. UDOMI is an SME partner who offers the link to the stationary fuel cell trading branch in which the hydrogen supply at the specified quality is of great importance. The inclusion of SME end-users (MFN, PROTON Motor and BITTER) will guarantee the right orientation of the project. FRONIUS as a non-SME demonstrates without getting funding its interest in the technology to be developed. The SME partners will perform the dissemination. UNI NITRA which will be responsible for the dissemination in New Member Countries in Middle and Eastern Europe.
