Abstract:
The Horizon Europe project Micro-Bio-CHP aims at the development of an innovative system for heat and electricity supply to achieve an almost energy autonomous multi-family building with regard to heating and electricity consumption as well as electro-mobility. This shall be reached by integrating a biomass CHP plant, a PV system and appropriate heat and electricity storage technologies. One main focus of the project is the development and test of the projects core technology, the biomass conversion unit and especially the generation of a clean product gas for the SOFC. Necessary development work covered the CFD-aided development and optimisation of a new gas burner with integrated thermal and catalytic tar reformer as well as of the high-temperature particle filter, the selection and lab-reactor tests of suitable tar reforming catalysts as well as the design and construction of a 15 kW testing plant. Test run results show that stable operation is possible and an almost tar as well as particle free product gas can be generated for the SOFC. Through a stepwise optimisation process a tar reduction of 99.5% and a minimization of the dust contents of the extracted product gas to levels in the range of 1 mg/Nm³ could be achieved. For the Micro-Bio-CHP process a novel gas extraction and cleaning technology has been successfully developed and tested. All innovations represent novelties in micro-scale biomass CHP concepts, which clearly go beyond the present state-of-the-art. Thus, the Micro-Bio-CHP system can represent a new milestone in clean product gas production from biomass.
