  1. DESERTEC10,000 GW FROM DESERTS BY 2050Large-scale deployment of BSE/Luz II solar towersEnergy Forum, Hannover, April 24, 2008 USA 1999 Harrison Street, Suite 500, Oakland, California 94612, Tel.

  2. “1,000 GW capacity by 2050” The technology and component availability Approach to the desired technology and at market-driven quantities Solar energy in the desert - availability and transmission Potentially recognized and assumed for this presentation Solar electricity price How to reduce solar electricity price to half of current state of the art trough technology, is not presented here.

  3. What’s the approach? • The BSE / Luz II way

  4. Original Luz Solar Trough Design* Modular Solar Field Centralized Power Block The 354 MW of original Luz plants have generated over 11,000 GWh of electricity worth more than $1.7 billion in revenue * Still used by many competitors

  5. Technology & Design Philosophy • Compete with conventional power production: • solar steam parameters equal to conventional energy steam parameters • Follow global market trends to minimize costs: • use available materials and components • Implement technology as it becomes available • Build DPT 550 plants (subcritical) as DPT SC1 technology (supercritical) is developed 5

  6. Luz II Distributed Power Tower (DPT550) Solar Boiler Steam 550°C 165 Bar Electric Generator Steam Turbine Calibration Target Solar Tower Receiver 7m2 Heliostat Air Cooling 5500C Steam to power block Steam Condenser Solar Field Heliostats Tower

  10. 1,000 GW by 2050 • Major equipment items would otherwise be produced for conventional power requirements • power block equipment including turbines • boilers • Towers and heliostats are fabricated from plentiful, conventional materials such as steel and glass • As an example, ~5 billion m2 of mirrors will be required for 1,000 GW • roughly equal to one year’s glass production worldwide (2005 figures) • But spread over 30 years, it is only 3% of the world glass market
