EU grant for biofuel capable SOFC power plants
The EU has awarded a grant of €5.8 (US$7.5) million to a European consortium undertaking a three-year project to develop Large Solid Oxide Fuel Cell-based (SOFC) power plants that run on a multitude of fuels, including biofuels (on biogas powered fuel cells, see earlier post).
The project, ‘Towards a Large SOFC Power Plant,’ started on January 1, 2007, with a total budget of €11 (US$14.2) million. The project focuses on materials, components and systems required for efficient, reliable and cost effective large scale SOFC power plants. Systems design, balance of plant component engineering, such as heat exchangers, and the processes and materials required for low cost stack production are included in the project.
Solid Oxide Fuel Cells (click image to enlarge) work at very high temperatures, typically between 700 and 1,000ºC. In these cells, oxygen ions are transferred through a solid oxide electrolyte material at high temperature to react with hydrogen on the anode side. Due to the high operating temperature of SOFC's, they have no need for expensive catalyst, which is the case of proton-exchange fuel cells (platinum). This means that SOFC's do not get poisoned by carbon monoxide and this makes them highly fuel-flexible.
The possibility for stack production will be critical for the successful commercialisation of the concept, so the project will study the production of large quantities of stack for non-pressurised CHP (combined heat-and-power) units and pressurised units producing only power. Reviewing the issues of grid connection, fuels and environmental impact are also included in the project.
The consortium expects the units to be on the market in the middle of the next decade. Success of the units will be measured by a combination of high fuel efficiencies, low emissions, multi-fuel capabilities and use of bio-fuels including gas from biomass gasification, biogas from the anaerobic fermentation of biomass and natural gas.
The use of biofuels forms part of a separate project, run by France's Centre de Coopération Internationale en Recherche Agronomique pour le Développement (CIRAD), called 'SOFC Fuel Cell Fuelled by Biomass Gasification Gas' which aims to develop a tar decomposition and gas cleaning system that can be integrated with woody biomass gasifiers, in order to produce a gas with suitably low tar content for solid oxide fuel cell (SOFC) applications. Two approaches to tar removal based on char beds - with and without bed material – will be developed and evaluated. The project will also determine the requirements of the gas cleaning system to ensure that the inorganic impurities are removed to an acceptable level. To demonstrate the feasibility, two laboratory or pilot-scale systems comprising the complete chain from gasifier to SOFC stack will be operated for 100 hours.

SOFC-based power plants are currently under rapid development. First demonstrations can be expected in the end of the decade. Sizes of the plants will range from 20 – 50 kW to 250 kW and up to 1 MW, using pressurized and non-pressurized technologies. These units will be suitable both for CHP and power-only in distributed generation applications.
The research consortium working on the SOFC power plants is coordinated by VTT Technical Research Centre of Finland and comprises nine collaborators from EU member states: VTT Technical Research Centre of Finland, Wärtsilä, Rolls-Royce Fuel Cell Systems, Topsoe Fuel Cell, Forschungszentrum Jülich, Dipartimento di Ingegneria Chimica e di Processo ‘G.B. Bonino’ - Università di Genova, Bosal Research, Verteco and Inmatec Technologies.
