Description
The European Council in 2007 adopted ambitious energy and climate change objectives for 2020 – to reduce greenhouse gas emissions by 20%, rising to 30% if the conditions are right, to increase the share of renewable energy to 20%, and to make a 20% improvement in energy efficiency. Achieving energy- efficient Europe is the first out of the five priorities of the new energy strategy. Therefore in the market need, the steam high temperature turbine engine remains the prim over of power generation. Thus any significant technological improvement towards better performance and energy efficiency in this field of turbines will have a direct positive impact in the short term on energy strategy in Romania and Iceland. This project involves the research activities, and networking among universities, R&D performers, material producers and designers and the geothermal power end-users. European dissemination and knowledge transfer from universities/R&D performers will be realized by rapid results access by the project meetings, progress reports and technical reports. For companies involved technical data will be made available through existing communication channels (journals and newsletters, symposia) and interactive actions (scientific platform, workshops, helpdesk). For Iceland the reparation of the turbines are now very important and need for the power companies to have spare rotor available at all time. This is both costly and due to transport and thereby a longer time for the rotor to be out of use for the power companies. Icelandic research priorities within materials have been for some years focusing on materials for geothermal environment. This is not least because the environment differs from one site to another and therefore materials selection cannot be transferred from site to site without consideration.
Summary of project results
The European Council in 2007 adopted ambitious energy and climate change objectives for 2020: to reduce greenhouse gas emissions by 20%, rising to 30% if the conditions are right, to increase the share of renewable energy to 20%, and to make a 20% improvement in energy efficiency. Achieving energy- efficient Europe is the first out of the five priorities of the new energy strategy. Therefore in the market need, the steam high temperature turbine engine remains the prim over of power generation. Thus any significant technological improvement towards better performance and energy efficiency in this field of turbines will have a direct positive impact in the short term on energy strategy in Romania and Iceland. The aim of the GEOTUR project is to develop new material classes, methods and models suitable to fabricate, monitor, evaluate and predict the performance and overall energy efficiency of novel corrosion-erosion barrier coatings in geothermal turbines systems. New structural design of isolative and durable protective layers was optimised for the deposition of Top Coats by new multicomposites materials, coupling the process of preparation and coating into a single step. GEOTUR created new direction of design and synthesis of complex powder mixtures NiCr/NiCoCrMo with different addition of WC and B. Materials were used to obtain protective layers, with improved wear, and corrosion resistance of specifically steam geothermal abrasion and corrosion. GEOTUR obtained preindustrial realization and optimisation of new materials and technologies at laboratory level and complex study of the set-up of the pre-industrial processing procedure in order to obtain components with enhanced surface properties. These coatings formed by Thermal Spray Process have ecological advantages compared to other chemically or electrochemically methods widely used in powder engineering industries. There are considerable differences between benefits expected when the relevant project is in the assessment phase and the benefits really attained after the project has reached the stage of routine operation. In term of market impact and potential benefits despite of some variations our findings are conformable with the outcomes of similar surveys in Iceland and Romania. Geotur outcomes: research and technology development of thermal sprayed applications, 12 article publication, 2 Patent Applications, and 2 participations at EUROINVENT-European Exhibition of Creativityt and Innovation.
Summary of bilateral results
The project has includes research activity in direction to create benefits on several levels: Programme Operator, Project Promoters, Project Partners as including some numbers of PhD students and graduates students whose research activities are supported by the Iceland Programme EFTA funding. This project was involves research activities, and networking among universities, R&D performers, material producers and materials engineer designers and the geothermal power end-users. European dissemination and knowledge transfer from universities/R&D performers was realized by rapid results access by progress reports and technical reports. For companies involved technical data was made available through existing communication channels developed by GEOTUR project. The project was bilateral and synergetic and the project whas dedicate to complementarities of scientific activity Romania - Iceland research on the global green energy development, improving capacity at national and regional level and synchronizing the effort to obtain more access of geothermal energy. Briefly, the bilateral partnership contributed to the project (e.g. in terms of streng th the ning results, innovation, visibility) as follows: Patent Applications 1. Hybrid technology for obtaining multicomposite layers to protect the geothermal turbine blades. OSIM Patent application no. A /00033. 2. A method of producing of multicomposite type metallic layers for the protection of the geothermal turbines rotor shaft and diaphragms. Patent application no. A /00034.
