Introduction MATChING is the acronym of a project titled: “Materials & technologies for performance improvement of cooling systems in power plants” which has been submitted for the call NMP-15 of H2020 EU funding program. CALL NMP 15 – 2015 is on “ Materials innovations for the optimisation of cooling in power plants ” The CALL is within Section 5 of HORIZON 2020 – WORK PROGRAMME 2014-2015 : Leadership in enabling and industrial technologies. Nanotechnologies, Advanced Material, Biotechnology and Advanced Manufacturing and Processing MATChING has been selected for funding and it is now in the phase of Grant Agreement Preparation Current Status 3 3
Background Background European Commission’s Resource Efficient Europe Roadmap 2050, indicates that by 2020 “ Water abstraction should stay below 20% of available renewable water resources ”(1). MATChING aims to reduce the water demand and improve Power generation is a sector requiring great amounts of water: cooling water for energy efficiency for cooling energy production accounts in fact, for 43-45% of total water abstraction in European systems in the energy sector Union second behind agriculture (2,4). through the use of advanced and There is currently a gap between water demand and water availability. Following the nano-technology based materials business as usual approach this gap is expected to increase in the upcoming years and innovative configurations (3): to meet EU requirements, Additional innovation actions are needed.

The Objectives of MATChING Two areas of the energy sector have been taken into account: Geothermal and Fossil fuelled plants Thermal Power Plant Geothermal Power Plant Increase the robustness of cooling equipments to allow the use OBJECTIVES of non-traditional waters; Reduce evaporative losses and plume visibility in Increase the heat exchange efficiency of condenser and geothermal power plants to increment the geo- cooling equipments; fluid re-injected fraction; Promote the use of alternative water sources (low quality waters, blow down waters, municipal waters) Overall plant efficiency increase up to 0.4-0.5%, enhancing the heat transfer efficiency in the condenser both on the Overall reduction of geothermal steam emitted into the steam side and water side via the use of advanced nano- TARGET atmosphere up to 15% and extension of production wells engineered coatings and surfaces.. life up to 10% using hybrid solutions for cooling towers and advanced materials and coatings for dry modules Overall reduction of fresh water abstraction in fossil fuelled power plants of about 30% validating a set of solutions (6) for the recovery and treatment of cooling water in CT equipped plants. 5
