Concentrating Solar Power

Transcription

1 Concentrating Solar Power Technology, deployment and research perspective Dr. Karl-Heinz Funken on behalf of Prof. Dr.-Ing. Institute of Technical Thermodynamics Solar Research German Aerospace Centre (DLR) Linder Höhe, D Köln

2 Development of European electricity demand and its coverage by power plants already existing in 2000 moderate increase due to efficiency gains and sociodemographic development significant investments required to replace old plants targets for reduced CO 2 emissions and increased renewable sources window of opportunity for restructuring of electricity sector and to reduce dependency on imported fuels

3 Development of MENA electricity demand, and its coverage by power plants already existing in 2000 significant increase due to economic and population growth significant investments required for new plants window of opportunity for sustainable local electricity and water supply potential of future electricity exports unique opportunity for closer economic, political and social links with Europe

4 Renewable energy resources in Europe and MENA in brackets: (max. yield in GWh el / km² /y)

5 renewable resources greatly exceed the present and future electricity demands solar radiation is by far the most abundant source of energy Economic renewable electricity potentials vs. demand in Europe and MENA

6 renewable resources greatly exceed the present and future electricity demands solar radiation is by far the most abundant source of energy 1 km² of desert land may generate 50 MW of electricity 1 km 2 of desert land may produce GWh el / year 1 km² of desert land avoids 200,000 tons CO 2 / year Economic renewable electricity potentials vs. demand in Europe and MENA The electrical energy produced by a solar power Solar thermal power plants are the most plant effective with the size technology of Lake Nasser to harvest equals this the vast total ressource Middle East oil production

7 Why solar thermal power plants? Conventional power plants

8 Why solar thermal power plants? Solar thermal power plants

9 Why solar thermal power plants? can be integrated into conventional thermal power plants provide firm capacity (thermal storage, fossil backup) serve different markets (bulk power, remote power, heat, water) have the lowest costs for solar electricity have an energy payback time of only 6-12 months Solar thermal power plants
