focused on throughout the course of the NextGenPower project. Sub Project 1 – boiler NextGenPower aims at overcoming fireside corrosion and steamside oxidation in high temperature parts through the application of suitable coatings. The main goal for Sub Project 1 is to demonstrate the benefits and limitations of materials and coatings for the fireside under biomass co-firing conditions as well as for the boiler and main steam pipework under USC and current steam conditions. Sub Project 2 - steam turbine The main goals for Sub Project 2 are to select the best candidate alloys for the HP and ID steam turbines operating at high steam temperatures (≥720˚C). A number of nickel-base alloys have been developed whose properties have been proven at the laboratory scale and for small-scale components. The main uncertainty in the application of these alloys for steam turbine applications is the ability to manufacture, weld and inspect large components. The performance in service presents a much smaller risk since there is confidence that the mechanical behaviour can be modelled on the basis of the material properties. This philosophy follows the approach applied in the development, demonstration and exploitation of materials technology for 700-720˚C steam turbines in other projects (AD700, COMTES, EON 50plus) where the first commercial steam turbine will enter service without prior operation in a test loop. Following alloy selection, full-scale steam turbine casings and rotor forgings will be manufactured and materials properties demonstrated through implementation of a mechanical testing programme. Full-scale demonstration of the welding technology and the NDE capability required for welded rotor and casing manufacture will also be carried out. Sub Project 3 – integration Sub Project 3 provides a framework for the testing and demonstration work in the overall project. It will review the expected operating parameters required for NGP plants, with and without capture technologies, and with and without biomass co-firing. The aim is to evaluate a series of NextGenPower plants with CCS systems in terms of their power generation efficiencies and emissions per unit of electricity generated. Sub Project 4 – dissemination The main goal for Sub Project 4 is to ensure that the generic results and results from topical activities are actively disseminated. It promotes results and approaches and encourages the duplication in other, thereby contributing to EU objectives of the reduction, efficiency improvement and security of energy supply. Another objective is to facilitate the sharing of policies, approaches and
