Presentation of Leonardo ENERGY Initiative and an example of available resources on concentrated solar technologies.

1. ICREPQ – April 2009 New Technologies for Small and Medium Scale Solar Power Plants Fernando Nuño www.leonardo-energy.org [email_address]

4. Kind invitation to actively participate… Conferencing interactive system You are all invited to make your presentation You are all invited to attend http://www.leonardo-energy.org/discussion-webinars

6. But not only on the web Low Carbon Electricity Systems Congress 16 th June 09 Arnhem – The Netherlands Large-scale wind energy systems Electricity storage Quality of supply Smart Grids Concentrated Solar Power Ocean Energy – State of the Art Electric Vehicles Strategic Energy Technology Plan Participation is free of charge, but seating is limited Register at: http://www.leonardo-energy.org/

7. For those who already know about us… We have a new look since Monday 13 th April…! Easier navigation Structured contents Better adapted search engine

11. Solar roadmap – Increasing role in the coming years

12. Where does solar energy make sense? Source : Schott Solar

13. Why solar energy fits well in hot climates Spanish average load profile vs average irradiation Source : Red Eléctrica de España

18. CPV - Advantages No water needs Time to Operation Less sensitive to hot climates Modular / Scalable

22. CPV – Components: Concentrator - Technologies

23. CPV – Components: Concentrator - Technologies Central tower CPV Developed by Solar Systems in Australia

26. CPV – Area reduction For the same surface, almost 50% more installed power To reach the same power, 30% less need for materials Source : Concentrix
