High temperature solid oxide fuel cell integrated with novel allothermal biomass gasification

The use of biomass syngas in IC engines and CCGT plants: A comparative analysis

“…On the other hand, in open literature it is possible to find several works on the innovative coupling between biomass gasification and fuel cells [1][2][3][4][5][6][7][8][9], whereas works on the coupling with traditional power generators, such as IC engines and gas turbines, are relatively scarce [10][11][12][13][14][15][16][17].…”

Performance analysis of integrated biomass gasification fuel cell (BGFC) and biomass gasification combined cycle (BGCC) systems

“…(Shen et al, 2008) This scheme avoids dilution of the resulting syngas with nitrogen whilst avoiding the use of an oxygen plant (air separation unit) for supplying pure oxygen to the gasifier. Panopoulos et al (2006) have proposed a biomass allothermal fluidised bed gasifier comprising steam gasifier, tar cracker and combustor, operating at around 800 o C to produce a medium calorific value gas mixture, rich in H 2 , CO, and CH 4 , which are fuel species for SOFC. These schemes avoid dilution of the product gas with nitrogen whilst avoiding the use of an oxygen plant (air separation unit) for supplying pure oxygen to the gasifier.…”

“…While biomass gasification combined cycle (BGCC) is a proven technology (Bridgwater et al, 2002;Craig and Mann, 1996), a fully integrated biomass gasification fuel cell (BGFC) is yet to be established. Panopoulos et al (2006) had studied the integration between an allothermal biomass gasifier and a SOFC, both operating at an atmospheric pressure, for small scale CHP generation, which was assessed by modelling in Aspen Plus process simulation software. The gasifier consisted of two fluidised bed reactors.…”

“…In addition to the process integration challenges that exist between biomass gasification and SOFCs, a major hindrance to the commercialisation of a BGFC system is the stringent tolerance limits on the contaminants required for the SOFC feedstock (Panopoulos et al, 2006). The most common contaminant in the syngas feed to a SOFC is H 2 S which originates from the raw materials used in gasification.…”

Process simulation of biomass gasification integrated with a solid oxide fuel cell stack

“…Biomass gasification coupled with solid oxide fuel cells (BG-SOFC) offer much higher efficiencies. These systems offer highly efficient renewable energy, are modular in nature making them ideal for decentralised combined heat and power (CHP) applications and as a result have recently gained much attention [1][2][3][4][5][6][7][8][9]. For a comprehensive list and description of research on BG-SOFC systems, refer to Nagel [4] and Doherty [10].…”
