  • 9. (II) TECHNOLOGY
  • 10. SunCatcher 25 kW solar power system The system consists of a solar concentrating dish structure that supports an array of parabolic mirrored facets Dish concentrator tracks, collects, and focuses the Sun s energy onto solar receiver tubes which contain hermetically sealed hydrogen gas This heats and pressurizes the gas in the heater head tubing, powering a high-efficiency four-cylinder, reciprocating Solar Stirling Engine The Stirling engine converts thermal energy to grid- quality electricity by utilizing hydrogen as an internal working fluid that is recycled through the engine A new paradigm clean energy solution 10
  • 11. SunCatcher Key Components

  • 20. (IV) UTILITY SCALE VERSUS DISTRIBUTED SYSTEMS
  • 21. Large V Small Scale Solar June 29th 2010 ... energy experts now say developers' focus should be on deploying smaller solar plants ... But can CSP tap into this interim market for SunCatcher Technology Attributes distributed energy, or must it always be limited to utility-scale applications? Lowest Cost Building large central station solar plants and Lowest Water Use transmission lines to remote desert locations also involves major environmental trade-offs in Highest Efficiency terms of water usage and impact on virgin desert Modular Design The technology that is expected to dominate the distributed generation market is Terrain Flexibility & Minimal Land photovoltaics (PV). Most agree that CSP will Disturbance be left to niche applications. Scaling down SunCatcher technology is easier than other CSP due to low water usage and modularity 21
  • 22. Solar Technology Landscape <10kW to 100MW 25MW to >100MW Dish systems occupy a unique space between conventional CSP and PV Systems
  • 23. SunCatcher Modularity The modularity of the design allows commissioning of smaller blocks which significantly reduces commissioning risk and enables revenues during the construction phase
