SOFC Fuel cell fueled by biomass gasification gas

Objetivo

Electricity consumption is increasing in most countries within and outside the EU. Thus there is a demand to increase the efficiency in the electricity production. Electricity production by SOFC fuel cells is one road to obtain a high efficiency in electricity production. In order to meet this demand in a sustainable way, this project will develop a gasification technology that can produce gas for SOFC fuel cells. For gasification SOFC fuel cell conversion systems, based on biomass, the most cost-effective size is expected to be plants from 1 to 30 Mews. Electric efficiencies above 50% are expected. The main barriers are: Staged fixed-bed gasification producing a very clean gas cannot be up-scaled to more than 5 Math. The output gas from all other gasification systems without extensive and expensive gas cleaning systems is still to dirty to be fed into SOFC fuel cells, ·The price of SOFC fuel cells is still very high due to the technology's immature state and the lack of economies of scale. In order to overcome the first barrier, the objective of this project is to develop up scalable tar cleaning technologies based on char beds integrated into staged gasoliers. One char bed with bed material and one char bed with out bed material will be built and tested. The advantages of the two designs will be evaluated and compared. By implementing this technology gasoliers can produce a gas that can meet the requirements for fuel for SOFC fuel cells through reliable, up scalable and cost-effective staged gasification of biomass. The requirement of the gas quality for an SOFC fuel cell will be determined. Experiments with material from SOFC will be conducted to set up fuel cell specifications. Furthermore a long term testing of two complete integrated gasification-fuel cell stacks plants will be performed on woody biomass. Parallel to this, tar formation and decomposition as well as behaviour and removal of inorganic will be investigated.
