CSP Technologies
Left: Parabolic Trough collector: 64 MWelpower plant Nevada Solar One; dimensions:collector aperture width 5 m (Morin, 2010)
Linear Fresnel Collector: 1.4 MWel plant PE1 inMurcia, Spain; dimensions: receiver height abovemirror field: 7 m (Novatec, 2010)
Solar Tower plant PS10, 11 MWel inSeville, Spain (Abgengoa, 2010)
Dish Stirling prototype plants of 10 kWel eachin Almera, Spain; diameter 8.5m (DLR, 2010)

CSP Market Shares and Development
Parabolic Trough today over 90% market share, today
Other CSP Technologies gaining market shares 20 GW installed CSP capacity by 2020 is feasible
BUT: Reliable financial and political framework needed !

Conclusion CSP Components Production in MENA
Near-term: Low-Investment and Low-Complexity Activities in MENA:
Collector Assembly
Collector Installations
Civil: Groundworks, Collector Foundations, Buildings, Infrastructure
MENA manufactoring of approximately 17% of plant invest(+ optional EPC, Proj. Management)
If sustainable MENA-CSP-Markets are given:
More investment-intensive and more complex CSP-Activities in MENA:
Mirror Production
Receiver Production
Other specialized components and processes
Local Value Creation: up to 80% of plant invest
