Sørensen AAU Break Feedback Chair, Kim Nielsen RAM

3 Objective of Introduction To introduce the strategic research project/alliance Structural Design of Wave Energy Devices Through: Whyis utilization of wave energy interesting and necessary? How can this be done? Whatis the problem? Present the approach of the SDWED project.

4 Why wave energy? As with other renewable energy sources: Climate change (CO2 problem) The finite ressource of fussil fuels (oil, coal, gas, uranium) Security of supply political stability Jobs Never say never 1974, Risø report: Vindenergi vil aldrig kunne bidrage væsentligt v til elproduktionen i Danmark Vindenergi vil aldrig blive rentabelt (TW) 40 = 3.4 kw IEA Oil 10 Gas 5 Coal U RE ?

5 Potential ocean energy worldwide Wave 3.0 (net) 3.7 (gross) TW (TW ~ W) Ocean currents 0.05 TW Tidal currents 0.2 TW Temperature gradient 3.8 TW Osmose / salinity 2.3 TW Global energy needs~ 15 TW (2005) (140 x kwh/year) electricity ~10 % Note: Global solar energy: TW ca times world consumption! (Mørk et al., 2010)

6 Annual Net Theoretical Coastal Wave Power Worldwide (excluding contributions where P 5 kw/m and potentially ice covered areas)

7 Potential wave energy in Europe Denmark's electricity consumption: 3,7 GW Danish West coast (offshore): Up to 25 MW/km averagely 16 MW/km Around 150 km from the coast ~ 2,4 GW In the European Atlantic/North Sea coasts: MW/km Mediterranean sea: 4 11 MW/km Total potential on European coasts: 286 (net) 381(gross) GW

8 What technologies are used for harvesting wave energy?

22 Very large numbers of ideas... Hundreds of concepts for utilization of wave energy and even more patents! Still new concepts coming and being tested No convergence so far... So, what is needed to aid development of winner technologies? Common base/methodology for comparisons of very different technologies Development of more complete (wave to wire) models Economically reasonable/optimal safety levels Financing demonstration projects are very expensive!

23 The Alliance The Project: Structural Design of Wave Energy Devices Objective of the project Strengthen and consolidate Denmark s position as one of the leaders in wave energy research, through the formation of a strategic international research alliance focusing on the structural design of Wave Energy Devices Project granted by the Danish Council for Strategic Research Call: Strategic Research in Sustainable Energy and Environment Theme: Energy Systems of the Future 5 years ( ) 12 Partner organizations 6 Danish (73 %), 6 International (27 %) Budget: 25 mil. dkr. (19.6 DSF, 5.4 Co fin. )

24 Scientific, commercial and societal sub objectives Increase knowledge on loads on Wave Energy Devices, primarily through the development of models for floating structures taking into account hydrodynamics, moorings and power take off; and the establishment of protocols for design of Wave Energy Devices. Createlasting relations between Danish and international top institutions working in the field to achieve greater research capability. Increase the reliability and decrease the cost of Wave Energy Devices in such a waythattheycanfeasiblycontributeto energy supply. Finally, the main societal objective is to improve and consolidate the competitiveness of Danish wave energy, repeat the Danish Wind Adventure in a new sector and thus create both growth and knowledgeintensive jobs for Danish society.
