Sørensen background Business and university background PhD, 40 years with business development Project management large projects Ocean wave and tidal energy (Wave Dragon, Tideng) Offshore wind (Middelgrunden 40 MW and Samsø 23 MW) Committees Danish Wind Turbine Owners Association, board European Ocean Energy Association, vice president # 2

4 What to look for? Living in the Danish, Swedish and Norwegian part of the North Sea, Skagerrak and Kattegat when looking at utilising the sea for energy purposes The enormous potential for power general - maybe not so much in the first years directly as energy supply but The impact in the region in form of infrastructure and supply base # 4

5 Offshore Wind The WINDSPEED approach: How to use the North Sea wind potential optimal not being bound by national thinking WP3: Inventory of current and future sea uses WP2: Cost inventory of offshore wind energy WP4: Develop Decision Support System (DSS) WP6: Scenario analysis of spatial priorities WP6: Roadmap and policy recommendations Stakeholder consultation # 5

6 Spatial Inputs Cables & Pipelines Military Sand Extraction Shipping Density Shipping Routes Oil & Gas Platforms Fisheries Nature Conservations Zones Fish species richness Benthic value Bird Sensitivity Existing and Planned OWP shipping Marine wildlife vulnerability Military zones Spatial usage patterns and nature values were collected for the entire study area and harmonised for use in the DSS along with exclusion rules that dictate how each sea use function interacts with OWE # 6

9 Grid Connections The scenarios fall into two broad categories in regards to the connection philosophy assumed for future OWE. The first is for radial connections only, whereby countries continue to connect individual parks back to shore with HVAC or HVDC technology as seen today. The second is a mix of radial connections (for near shore resource), along with an offshore meshed grid where further from shore OWE clusters are directly interconnected using HVDC technology (see below).

11 Wave Dragon principle The Wave Dragon is a slack-moored wave energy converter that can be deployed alone or in parks wherever a sufficient wave climate and a water depth of more than 25 m is found.

22 Tide around the Faroe Island Between Streymoy and Sandoy A Tideng Power Plant can produce 8.15 GWh/y when the current is 2 m/sec as mean value # 22

23 Streaming water in rivers etc. Tideng may be placed in rivers without blocking shipping, fish or currents to any considerable extent.

24 Streaming water after traditional dams Tideng may be placed in front of existing dams and reuse the water which is pumped out for new energy production There are more than 48,000 dams more 15 metres high More than 1,600 dams are being built. # 24

25 Combined wave and wind A 1.5 MW unit can produce 3.000MWh/y and 1.3MWh/y with two windturbines # 25
