  17. 17. Surface conditions Cleaning properties are determined by wettability Hydrophilic Hydrophobic Super-hydrophobic contact angle << 90° contact angle ~90° contact angle >> 90° “self cleaning” IF rinsing speed self-cleaning is high “easy-to-clean” “no wetting”Typical application on glass together with photo- photo catalytic effect (TiO2 particles) special applications inspired b nature i i d by t
  18. 18. Surface conditionsHydrophilic “self-cleaning” surfaces• Self-cleaning mechanism • Dirt particles are washed away by water wetting the surface • Requires high rinsing speed to work well – Typically installation angle of surface >70° (gravity drives water!) – Large amount of water • Well suited for environments with amply rain for badly accessible installation locations• Photo-catalytic effect • TiO2 particles in surface dissociate water molecules into super oxide and hydroxyl radicals, which decompose organic residues on the surface e g bacteria lichen fungal attack surface, e.g. bacteria, lichen, • No effect to inorganic dirt, e.g. sand, dust, lime-scale
  19. 19. MIRO-Sun Easy to clean surfaceHydrophobic “easy-to-clean” surfaces• Decreased sticking of dirt on surface dirt is easily removed when rinsed with water• Rinsing cycle requires less water water droplet on l f t d l t leaf• Easy drying due to decreased wettability of water without wiping trace• Can easily be dried by air blower without water residues on surface• Easy de-icing water droplet on MIRO-sun• Metal surface no static loads if grounded
  20. 20. Why do we need CSP ?The way of thinking of our modern civilization is based on afatal mistake:We do not see the fundamental difference inbetween energy sources and energy stores!Our global energy consumption is based mainly onENERGY STORES like fossil fuels and uranium with nosustainability and fatal consequences for future generations(climate change nulear waste) change,Our choices for the use of ENERGY SOURCES:(Electricity production per square kilometer of land use per year) Source: DLRBio Mass Power Plants 1-2 GWh/km²/a (Central Europe)Geo Thermal Power Plants 1-2 GWh/km²/a (Turkey, Italy, France)Wind Parks 5-50 GWh/km²/a (Coast and Offshore)Hydro Power 5-50 GWh/km²/a (Norway, Alps)PhotovoltaicsPh t lt i 10-100 GWh/km²/a (S th 10 100 GWh/k ²/ (Southern Europe) E )CSP 100-250 GWh/km²/a (North Africa) EFFICIENCY.

  28. 28. Installed cost of CSP has to go down,but how? New d ib th ?N designs? S l ? ? Scale? Metal Reflectors fit ideally into large scale productionprocesses: some examples 28
  29. 29. New concepts for CSP Heliotrough Is bigger better? And is glass still able to do the job if sizes are increased? 29
  30. 30. New concepts for CSP-Alcoa and National Renewable Energy LabTesting New Innovative Concentrating SolarPower System- Advanced Alcoa Wing Box Design andTechnology to Lower Cost to Generate Energyfrom the Sunf th S - 30% 30
  31. 31. New concepts for CSPThe World’s first MicroCSP Solar ThermalPlant “Holaniku at Keahole Point” onHawaii.2 Megawatt thermal energy project whichspans across 3.8 acres in the hot Konadesert utilizes 1,000 Sd t tili 1 000 Sopogy proprietary i tMicroCSP solar panels.With an unique thermal energy storagebuffer that allows energy to be p gy producedduring cloudy periods and to shift energyproduced from the day to eveningperiods. 31
  32. 32. New concepts for CSP Linear Fresnel Design with aluminium composite primary mirrors -More accurate form factor -Less weight -Simpler torque tube and fixation -Mirror is part of the structural design f 32
  33. 33. New concepts for CSP High temperature secondary mirrors for linear fresnel receivers
  34. 34. New concepts for CSPRadically new engineering approach forDishs and Heliostats-Drastically lower material usage-Increased form factor lead to higher overall efficiency-Short installation time allows mass field deployment-Drastically decreased cost /watt compared to existing gdesigns 34
  35. 35. New concepts for CST Concentrated Solar Thermal 35
  36. 36. The future of concentrated solar energy, new designs for self efficiency and self-efficiency reduction of global costs Conclusions •L Large production capacity will b crucial f f th CSP d ti it ill be i l for further development • Existing manufacturing facilities and processes will play an important role in this development • First examples show that metal mirrors are already choosen if p y it comes to large scale manufacturing. •Radically new designs starting from scratch are the most promising way to get installed cost down • PV is in CSP´s neck…. 36
