Abstract
The BiGPower project aims to develop reliable, cost-effective and fuel flexible gasification technologies for high-efficiency small-to-medium scale (1-100 Mwe) power production from biomass. The project is designed to create the fundamental and technical basis for successful industrial follow-up developments and demonstration projects aiming to commercial breakthrough by 2010-20. This overall project approached by carrying out in a pre-competitive manner well-focused activities on the key bottlenecks of advanced biomass gasification power systems.Three promising European gasification technologies in this target size range have been selected to form the basis for the development of the 2nd generation processes: 1) Air-blow novel fixed-bed gasifier for size range of 0.5-5 Mwe, 2) Steam gasification in a dual-fluidised-bed gasifier for 5-50 Mwe and 3) Air-blown pressurised fluidised-bed gasification technology for 5-100 Mwe. In all biomass gasification processes, the product gas contains several types of gas contaminants, which have to be efficiently removed before utilising the gas in advanced power systems. The key technical solutions to be developed are: a) High-temperature catalytic removal of tars and ammonia by new catalytic methods, and b) Development of innovative low cost gas filtration and the control of different gas contaminants by sorbents (HCl, and alkali/heavy metals).Three most potential power production cycle alternatives are examined and developed: 1) gas engines, 2) molten carbonate fuel cells (MCFC) and 3) the simplified Integrated Gasification Combined Cycle (IGCC) process. The performance and techno-economic feasibility of these advanced gasification-to-power concepts will be examined by carrying out detailed case studies in different European regions.
