The focus of IGCC development activities is therefore seen to be first on improvement of reliability and on reduction of specific costs. For further reduction of IGCC capital cost and improvement of commercial competitiveness, primarily of coal-based plants, more advanced and larger gas turbines will play a major role. They will enable larger IGCC units with higher efficiencies and reduced specific capital cost. On the other hand greenhouse gas reduction strategies will in the future also requıre power plant solutions with CO2 capture and sequestration, and one of the promising options for such future coal-based power generation is IGCC. Both applications require a proper and optimized integration of the gas turbine and the power island, respectively, in the overall plant, considering the operational requirements of the individual application and the lessons learned from design, construction and operation of the existing IGCC plants. in addition to that, the capability of advanced gas turbines for operation with medium to high hydrogen content syngases is of importance for future applications. These aspects are addressed in several funded development programs in which Siemens have committed to participate or even have the lead. in these programs utilities or operators of existing European IGCC plants are involved as partners, e.g. to support market research, to push development of advanced concepts or to specify customer requirements for syngas-related gas turbine applications. On the other hand greenhouse gas reduction strateaies will in the future also require power plant solutions with C02 capture and sequestration, and one of the promising options for such future coal-based power generation is IGCC. 1 ENERJİ DÜNYASI EKiM 2006 781 One of the projects, initiated and coordinated by Elcogas, was aiming for the pre-design of next generation and more powerful IGCC plants based on the design optimisation potential identified as result of the operating experience gained at the Puertollano plant. This effort was supported by another EC-funded development program aiming for improved fuel flexibility of syngas-proven gas turbines with silo-type combustion chambers, and for development of flexible advanced syngas burner technology for SGT5-4000F gas turbines (formerly known as V94.3A). in addition to several European partners and research institutes which were involved in this Siemens-coordinated program, also Nuon, the operator ofthe IGCC plant at Buggenum, and Enel joined the team to bring in customer's requirements. At the 5th European Gasification Conference, held in April 2002 in Noordwijk/ The Netherlands, the results of a study were presented by Siemens which was focused on the market potential for IGCC applications based on refinery residues, and on related IGCC plant concept standardisation efforts. The major findings of this study, which was focused on power generation only, are stili valid. But as present market activities primarily in Europe show, future IGCC plants are expected to also be used for combined heat and power or co-production applications to maximise feedstock utilisation and revenues from product mixture.
