FRESH NRG · FREsnel for Solar Heat with New Receiver and Geometry

FRESH NRG will target efficiency of 60% at 250°C with a Linear Fresnel Collector (LFC) optimized for industrial use. Our integrated approach will design, implement and test disruptive innovations in 4 key parts of the value chain.Highly innovative sol-gel coatings will target robustness, durability and performance (transmittance >96%, absorbtivity >95%, emissivity250°C <7%).To increase the annual yield, a LFC design with radically new geometry will target differentiation of the width of the primary mirrors and concentration factor >90 to limit heat losses. Ultra light mirror panels will target safety, durability and reflectivity >93%. Modular “plug-in” components (e.g. clip-on secondary mirrors) will simplify transport and installation.Laboratory and field tests of the new LFC and its key components will include existing methods (e.g. EN12975) and methods that are currently revised or will be developed in IEA-SHC/SolarPaces Task 49.A first-of-its-kind lean manufacturing system including receiver assembly and optimized processes to reduce cost and ensure mirror optical accuracy will be prototyped and co-located to optimize cost reduction.Integration packages for Mediterranean industrial applications will include a new control logic to optimize energy output for industrial use. A full blown polygeneration system in Jordan will provide actual use of the new LFC for power generation, heating and cooling.A clear plan for the exploitation of the technical results will include a highly multi-disciplinary approach. Detailed bottom-up prospection of high-potential applications will be analysed to drive industrial strategy towards a large economic impact. Relevant key findings will be shared also with policymakers and industry regulators.Knowledge dissemination will promote the innovative results of the project (e.g. comparison of test methods) to achieve a full scientific impact at EU level.
