CLEAN ENERGY Objectives There is a very strong interest worldwide in the development of technologies that allow the coupling of biomass gasification and fuel cell systems to have high-energy efficiency, ultra-clean environmental performance and near-zero greenhouse gas emissions. In this field numerous RTD programs are in progress in U.S.A. and other countries; this project is addressed at strengthening the co-operation among member States of EU, to maintain competitiveness in the global market. The technical programme is aimed at demonstrating the industrial feasibility of the integration of biomass steamgasification with a Molten Carbonate Fuel Cell (MCFC) for clean and renewable power generation. Achieving the above objectives involves the assembly and operation of an integrated pilot plant that includes: a 500 kWth gasifier, a hot gas clean-up system and a 125 kWe MCFC, as well as an ancillary work programme focused on key areas of direct relevance to the optimisation of the plant performance. Progress in coupling biomass gasification and MCFC stack Challenges To improve the efficiency of Biomass Gasification and Fuel Cell coupling. To prove the technical feasibility of this integration by operating a pilot plant which includes: • a 500 kWth fast internally circulating fluidised bed (FICFB) gasifier for catalytic biomass steam-gasification, with ancillary units; •a gas clean-up system for sulphur and chlorine compounds removal by adsorption on a basic powder, and ceramic candle fine particle filtration; • a 125 kWe MCFC. To carry out accompanying research activities in selected key areas which includes: • cold modelling studies of the fluid-dynamic behaviour of the gasifier in the presence of power load changes at the fuel cell • development of a comprehensive model for the gasifier, which combines overall reaction kinetics and heat transfer processes with fluidisation dynamics. • detailed simulation of the whole system and its components to develop optimal operation and control strategies. • catalyst upgrading, characterisation and testing over a wide range of operating conditions. To estimate investment and operating costs. Project structure The Consortium is composed of universities, industries and a national research agency. The University of L’Aquila (Italy), project co-ordinator, is involved in tasks related to the engineering of the integrated pilot plant and lab tests of catalytic steam gasification. The Technical University of Vienna (Austria) studies the system simulation 68 and performs gasification tests in its 100 kW th facility. The University College of London (United Kingdom) is involved in CFD comprehensive modelling of the fluidised bed gasifier and cold model tests. The University of Strasbourg (France) optimises the preparation of a purposely developed Ni/olivine catalyst and provides it for tests at process conditions. The companies are Ansaldo Ricerche S.r.l (Italy) and Pall - Schumacher GmbH (Germany) involved in the Hot Gas Clean-Up System (dechlorination reactor, cyclone and ceramic candle filter) and Ansaldo Fuel Cell S.p.A. (Italy) which provides the MCFC stack and designs the fuel cell BoP. The Italian National Research Agency ENEA assembles and operates the integrated pilot plant. Expected impact and exploitation Biomass-to-electricity systems based on gasification have a number of potential advantages. Projected process efficiencies are much higher than direct combustion systems. Process efficiencies are comparable to high efficiency coal-based systems, but can be achieved at a smaller scale of operation. Thus, not only does biomass close the carbon cycle, but gasification based systems, due to their high efficiency, reduce CO2 emissions per megawatt of power generated over conventional biomass power plants. Fuel cells hold great promise for both stationary and mobile electric power applications. The energy efficiency of these systems has been projected to approach 55% or even higher if cogeneration opportunities can be utilised. MCFC is a leading candidate for integration into advanced power

In addition MCFC is able to convert CO via an internal water gas shift reaction. In conclusion, integrated biomass gasificationfuel cell power systems offer an attractive combination of high energy efficiency, ultra-low environmental emissions, and near zero net greenhouse gas emissions, particularly for distributed power applications, given that with these systems high efficiency is possible even in low capacity units. Progress to date The activities developed regarding the existing gasifier have been: Pilot plant modifications and experimental runs which check and verify the values of the operating parameters and the fuel gas properties and composition, the site layout (to allow pilot plant extension), and the commissioning and construction of the steelwork structure needed to assemble the hot gas clean-up section. Regarding the new section of the pilot plant, the detailed design of the different components of the hot gas clean up system has been completed. The construction and assembling activities are in progress, and in the next phase the absorption reactor, the cyclone and the filter will be mounted and operated. The design of the MCFC system has been completed and almost all the components of the fuel cell stack have been bought and the fuel cell stack construction is expected in the next phase. The work programme accompanying the pilot plant Integrated gasification – fuel cell pilot plant located in Trisaia (Italy). design, construction and operation includes the following activities to be carried out: the facility available for cold modelling experimental studies of the fluid-dynamic behaviour of the gasifier in the presence of power load changes at the fuel cell has been refurbished and adapted to simulate different operating conditions of the gasifier; development of a comprehensive model for the gasification section of the FICFB reactor, combining overall reaction kinetics and heat transfer processes with fluidisation dynamics; the kinetic model to be implemented in the computer code has been chosen, and this (a commercially available CFD code) has been adapted to impose boundary conditions compatible with the geometrical structure of the gasification chamber; detailed simulations of the whole system and its components; improvement and optimisation of the preparation procedure of the Ni/Olivine catalyst, to achieve the optimum quantity of Nickel deposited and linked to the olivine structure; study of the reforming of tars, methane and the catalyst deactivation by coke deposition; preparation of a large quantity of Ni/Olivine catalyst (260 kg); catalytic gasification tests in bench and pilot scale facilities, which produced satisfactory results regarding the fuel gas quality (high hydrogen and low tar content), the Ni/Olivine activity as a function of running time, the low level of coke deposition on the particle surface and the resistance of catalyst particle to mechanical stresses. 69 INFORMATION References: ENK5-CT-2000-00314 Programme: FP5 - Energy, Environment and Sustainable Development Title: Biomass-Gasification and Fuel-Cell Coupling via High-Temperature Gas Clean-up for Decentralised Electricity Generation with Improved Efficiency – CLEAN ENERGY Duration: 36 months Contact point: Antonio Germanà Universita degli Studi di L’Aquila (I) Tel: +39-0862-414214 Fax: +39-0862-434203 germana@ing.univaq.it Partners: Universita degli Studi di L’Aquila (I) TU Wien (A) University College London (UK) Université Louis Pasteur (F) Ansaldo Ricerche (I) Schumacher Umwelt- und Trenntechnik (D) ENEA (I) Ansaldo Fuel Cells SpA (I) EC Scientific Officer: Garbiñe Guiu Etxeberria Tel: +32-2-2990538 Fax: +32-2-2993694 garbine.guiu@cec.eu.int Status: Ongoing
