4 Smoothed Power Output Video

5 Where to deploy the commercial devices? Current focus Area of interest

6 FPP: From P37 to P80 up to 2.6 MW wave power up to 5 MW Wind P37 Site-Specific Design P80 Designed for Probable Commercial Sites 80 m wide Min water depth 45 m

7 TRL is very linear

8 Scaled up Approach The Way We Develop Concept tests Design Optimisation Numerical modeling & engineering Commercial Prototypes & Small Arrays Commercial wave-basin and wave-flume tests Dry tests 4 Scaled p37 offshore tests Large scale P80 commercial arrays 8
