John Olav: Innovations in Offshore Wind Technology Through R&D

  1. 1. Innovations in Offshore Wind Technology through R&D www.nowitech.no John Olav Giæver Tande Director NOWITECH Senior Research Scientist SINTEF Energy Research John.tande@sintef.no 1
  2. 2. A big global market for offshore wind►Firm European commitment►2020: 40 GW; EUR 66bn►2030: 150 GW, EUR 145bn►Significant developments in China, Japan, Korea and USA►Near-term large market is for bottom-fixed wind farms►Increasing interest in developing floating concepts 2
  3. 3. Main drivers► Battle climate change Stern Review (2006): ..strong, early action on► Security of supply climate change far outweigh► Industry value creation the costs of not acting. IEA 2DS scenario: 15 % wind in global fuel mix by 2050Copy from IEA Energy Technology Perspectives 2012 3
  4. 4. NOWITECH in brief Research partners: Associated research► a joint pre-competitive ► SINTEF (host) partners: research effort ► IFE ► DTU Wind Energy ► NTNU ► MIT► focus on deep offshore Industry partners: ► NREL wind technology (+30 m) ► Devold AMT AS ► Fraunhofer IWES ► Det Norske Veritas ► Uni. Strathclyde► budget (2009-2017) ► DONG Energy Power ► TU Delft EUR 40 millions ► EDF R&D ► Nanyang TU ► Fedem Technology AS Associated industry► co-financed by the partners: ► Fugro OCEANOR AS Research Council of ► GE Wind Power AS ► Access Mid-Norway Norway, industry and ► Kværner Verdal ► Energy Norway research partners ► NTE Holding AS ► Enova ► SmartMotor AS ► Innovation Norway► 25 PhD/post doc grants ► Statkraft ► NCEI ► Statnett SF ► NORWEA ► Statoil Petroleum AS ► NVE► Vision: ► Vestas ► Wind Cluster Mid-  large scale deployment ► Vestavind Offshore Norway  internationally leading 4
  5. 5. Multidisciplinary Research Challenges O&M Wind turbine Sub- structure Grid LPC distribution of offshore wind farm (example)Key issue: Innovations reducing cost of energy from offshore wind 5
  6. 6. Exciting floating concepts (2011, 2,3 MW) (2009, 2,3 MW) BlueH (2007, 80 kW) NREL/MIT HiPRwind 6
  7. 7. The HyWind demo – in operation since Sept. 2009 Turbine power 2,3 MW Turbine weight 138 tons Draft hull 100 m Nacelle height 65 m Rotor diameter 82,4 m Water depth 150–700 m Displacement 5300 tons Mooring 3 lines D @ water line 6m D submerged 8,3 m Data from Statoil 7
  8. 8. One big advantage: relatively easy installation!► In-shore assembly in sheltered waters► Tug-boats for transport to site for installation► Alternative: WindFlip? 8
  9. 9. It is stable? Yes; according to Simulations and Test in Ocean Basin Lab (2005) 20Tower top displacement (m) 15 10 5 0 -5 -10 With stabilizer Without stabilizer -15 100 150 200 250 300 Time (s) 9
  10. 10. Connection to oil and gas installations Gas ~ turbines Electric loads (storage) subsea cable Wind turbineswww.sway.no► Wind farm operate in parallel with gas turbines  Saves fuel (~300 Sm3/MWhel) and emissions (CO2: ~600 kg/MWhel)► Little space available  No extra transformer at oil rig► Energy storage likely not economic 10
  11. 11. NOWITECH 10 MW reference turbine Initial design parameters  Nominal power output 10.0 MW  Design wind velocity 13.0 m/s  Tip speed ratio 7.7  Hub height 93.5 m  Turbine diameter 141.0 m  Design water depth 60.0 m  Wind & waves ala Doggerbank  (work in progress!) The NOWITECH 10 MW reference turbine introduces a new generator and support structure concept
  12. 12. Superconducting generators reduce weight  100 times the current density compared to copper  More than doubles the achievable magnetic field  Eliminates rotor losses  Operating at 20-50 K  New materials give new electromagnetic designs  Possible step-changing technologyCourtesy AMSC  Activity in new FP7 project application: InnWind 12
  13. 13. Optimization of the offshore grid ► Inside and between wind farms ► New market solutions are required ► New technology (HVDC VSC, multi- terminal, hybrid HVDC/HVAC, .. ) ► Protection, Fault handling, Operation, Control, Cost, Security of Supply 140 10 Number of cable configurations 120 10 100 10 80 10 60 10 40 10 20 10 0 10 0 5 10 15 20 25 30 Number of nodes 13
  14. 14. Innovative DC grid solutions for offshore windfarms avoiding need for large sub-stationConventional system +100 kV 33kV +100 kV
  15. 15. Remote presence reduce O&M costs► It is costly and sometimes impossible to have maintenance staff visiting offshore turbines► Remote presence:  Remote inspection through a small robot on a track in the nacelle equipped with camera / heat sensitive, various probes, microphone etc.  Remote maintenance through robotized maintenance actions
  16. 16. From Idea to Commercial Deployment 2014-16 Large Parks 2009 Pilot Park 2005 Commercial and Market Focus Prototype2001 Cost Focus Model test Technology Focus ConceptGraphic is copy from Statoil presentation on HyWind at WindPower R&D seminar; 20-21 January 2011, Trondheim, Norway
  17. 17. Rounding up► Remarkable results are already achieved by industry and R&D institutes on deep offshore wind technology► Technology still in an early phase – Big potential provided technical development and bringing cost down► Research plays a significant role in providing new knowledge as basis for industrial development and cost- effective offshore wind farms at deep sea► Cooperation between research and industry is essential for ensuring relevance, quality and value creation► Test and demonstration, also in large scale, is vital to bring research results into the market place► Offshore wind is a multidisciplinary challenge – international collaboration is the answer! 17
  18. 18. NOWITECH is a joint 40M€We make it possible research effort on offshore wind technology.Questions?  Integrated numerical design tools  New materials for blades and generators.  Novel substructures (bottom-fixed and floaters)  Grid connection and system integration  Operation and maintenance  Assessment of novel concepts www.NOWITECH.no 18
