STEEL TECHNOLOGY PLATFORM "Materials for Energy: recent achievements and next steps of the European steel Technology platform ESTEP" Dr. P. Gimondo EWEC Wind Conference Marseille – 17 March 2009 1 ESTEP’s main characteristics • Among the first ETPs (first contacts in 2002) created in Europe • Financially supported by the EU steel industry (no support from the EU Commission) • Focused on topics of general interest for Europe (CO2, energy, sustainable use of resources) • Living SRA • On its way to its first general approach (ULCOS project) 2 The SRA of ESTEP answers these challenges Reducing CO2 emissions directly in steelmaking and indirectly by offering light steel solutions Development of safe, clean, energy-efficient and cost-effective technologies Contributing to the development of energy sources for the future Promoting conservation of resources, recovery of wastes and societal value of materials 3 Organisation Mirror Group Member States Decision-making level of the Stakeholders Steering Committee M.
