Floating Power Plant Overview - Carsten Bech - Floating Power Plant - April 2010

  1. 1. Nordic Green II Silicon Valley, CA 27 April 2010
  2. 2. Wind and Wave in One In brief… 1 An ultra stable floating foundation for a hybrid renewable solution designed 3 for deep ocean operation invisible from shore. The design and construction of the platform and anchoring system is based on well proven off shore Wind turbines on floating technologies. foundations significantly increases the potential sites for off shore wind. 2 Wave energy harvesting using patented floats to extract energy from the waves and transform this to power. By extracting both the push and the lift energies, it is possible to extract 70% of the total wave energy. This has not been accomplished by any other system 2
  3. 3. Fulfills a Real Need Poseidon has what it takes to make a difference in the ocean energy industry  Only solution in the world that converts both wave and wind energy.  Exploits wind and wave resources in deep ocean waters due to the proprietary floating foundation.  Biggest capacity / footprint ratio in the industry with limited environmental impact and invisible from shore.  Over 10 years of R&D and a full scale demonstration plant documents the potential of becoming a market leader  Established off shore industry makes a perfect match to commercialization 3
  4. 4. Key Markets Utility Industry Poseidon provides stable, efficient, and cost effective clean energy. High production to footprint ratio and low maintenance costs. To be used at deep sea and in connection with off shore wind turbine parks. Oil Industry Poseidon is able to deliver on demand power for the secondary recovery process on offshore oil platforms and thereby avoid design and installation of a fixed off shore infrastructure. 4
  5. 5. The Poseidon is ONE of TWO technologies with the potential of effective wind power production at deep ocean waters 5
  6. 6. We have been out there - We have done it Test phase I completed – Test Phase II planned & financed 6
  7. 7. P37 – Our technology  Full Scale Demonstration Plant  Launched August 2008  Construction price: more than 7 mill. USD  Test window II until March 2011, with the possibility for extension  Placed 3 km north of Onsevig harbour  Grid and net connected  Weighs 350 tons (450 tons with ballast). 7
  8. 8. The P37 Platform  Triangular shape, 37 m wide against wave front, 25 long, 6 meters high  80% of construction submerged  Constructed to survive “50 year storm”*  Stable (low and slow movements) construction improves wave efficiency and supports wind turbines  Wave sheltered boat landing deck improves service window significantly  Advanced ballast system for optimal trim  Several off shore paint protection systems tested *Hsdim=2,6m and Hmax =4,7m (Hsdim is the mean height of the highest 1/3 of the waves in the 2 hour long 50 year extreme storm. In this storm one wave will be 4.7 m high Hmax) 8 Source: DHI and FPP
  9. 9. The Anchor Buoy  360 degree orientation ensures platform always faces the waves  Grid connection point (hub) – the platform can be disconnected and towed away  Based on offshore oil exploration technology like drilling rigs and Floating Production Storage and Off-loading (FPSO)  Weighs 30 tons, not ballasted 9
  10. 10. The Floats  6 meters long, 3 meters wide and 3.2 meters high  Floats weigh 4.7 tons each - can be ballasted up to 21 tons  Swings in an interval of 2.5 m at speeds up to 1 m/s  Anti-fouling paint system minimizes growth and optimizes flow through the water. Axle  Floats absorb 70% of wave energy  The unique concept, shape and ballasting Lift system secures the high absorption rate of the incoming wave energy Push FPP concept 10
  11. 11. P37 wind turbines  Three 11 kW Gaia Wind turbines  Annual production: 30,000kWh pr. turbine  Hub height : 12 meters  Rotor diameter: 13 meters  Optimal yield in moderate wind speeds (annual average wind speed 4,5-7,5 m/s)  Installation of turbines improves the stability of the platform 11
  12. 12. Locations Annual average wave energy (kW/m) At least 20-25 kW/m is needed to operate at competitive scale 12
  13. 13. Our Roadmap to success An inventors brilliant idea 1 Close cooperation with internationally renowned wind and wave research clusters 2 Over 10 years of persistent testing from basin to full scale off-shore installation 3 Strong commitment from key stakeholders 4 Financial support from 60 private investors 5 13
