SOLAR ENERGY
Most environment friendly source of green energy
Technologies: Photovoltaic Solar Thermal Energy Concentrated Solar Power
![Page 3: KS Energy and Sustainable Development Theresa Spitzer, Stefan Krammer, Patrick Reiter](https://reader030.vdocument.in/reader030/viewer/2022032706/56649de65503460f94adeb3f/html5/thumbnails/3.jpg)
Most promising technology for large-scale solar power generation in Desserts
Lenses or mirrors concentrate a large area of sunlight onto a small area
Concentrated light is converted to heat which drives a heat engine connected to an electrical power generator
CONCENTRATED SOLAR POWER

2003 TREC, Trans-Mediterranean Renewable Energy Cooperative
Desertec Foundation emerged from the Cooperative
2005 – 2007 Researches CDER(Morocco) NREA(Egypt) NERC(Jordan) University of Sana’a and Aden(Yemen) DRL(Germany)
HISTORY OF DESERTEC
![Page 6: KS Energy and Sustainable Development Theresa Spitzer, Stefan Krammer, Patrick Reiter](https://reader030.vdocument.in/reader030/viewer/2022032706/56649de65503460f94adeb3f/html5/thumbnails/6.jpg)
HISTORY OF DESERTEC
Result of studies: 15% of European final energy consumption
can be delivered with a „supernetwork“ of renewables
Most energy can be produced with CSP in deserts
Founding of Desertec Foundation in 2009

Cooperation between EUMENA Europe and Middle East and North Africa
Methods: CSP Photovoltaic Windparcs desalination stations
Until 2020 MENA and until 2050 Europe
AIMS AND VISIONS

400 billion Euros 350 billion for the grids 50 billion for the transport
15-30 eurocents/kilowatt-hour actual production costs
4-5 eurocents/kilowatt-hour if the demand increases
No commercial competitiveness at the moment
COSTS AND FINANCIAL SITUATION

OBSTACLES
Cooling requirement
Temperature and salt

GRID SYSTEM
Most promising Technology is HVDC Voltage about 800kV Cost effective and environmental friendly Transportation losses of only 10-15% HVDC like highways and conventional AC
system as country and city roads

VISION OF THE GRID SYSTEM

POLITICAL OBSTACLES
Instability in Northern Africa and Middle East
Closed border between Morocco and Algeria
Negotiations only in a broader sense Dependency on Northern Africa
Risk of expropriation of assets Reneging on license agreements Corruption and bureaucratic red tape
![Page 14: KS Energy and Sustainable Development Theresa Spitzer, Stefan Krammer, Patrick Reiter](https://reader030.vdocument.in/reader030/viewer/2022032706/56649de65503460f94adeb3f/html5/thumbnails/14.jpg)
COMPETITION WITH SMALL-SCALE PARADIGM
Europe has potential of renewables within borders Desertec will lead to monopoly Cost-effective? Faster Implementation
