  6. 6. Example of the CSP Experience of • Simple operation: use of air as heat transfer fluid without intermediary heat exchanger • Air temperature output: up to 650 ° C • Less expensive solar collectors than other types: Simple construction with locally produced materials, fewer imported components. 6 Cimar, Italcementi Group Ait Baha
  7. 7. Potential benefits • Financial savings from reduced energy consumption of fossil sources • Protection of the environment through reduction in CO2 production • Training of 4 PhD students and one post- doctoral on the industrial applications of solar energy • Generate Intellectual Property (3 patents, 12 publications) 7
