2 Agenda Changing climate and changing energy mix.... the wave energy resource that is out there!.. different roads lead to Rome.. one company that is going to get it!.. with the right technology.. with the right strategy 2

3 ... and I sensed a loud infinite scream passing through endless nature. * Edvard Munch: Skrik (The Scream of Nature), 1893 * Diary notes

4 As climate change is an inconvenient truth in desperate need for urgent action... 4

5 ... we already face a shrinking polar ice cap and melting glaciers world wide in an accelerated manner An 1870 postcard view of the Rhone glacier in Gletsch, Switzerland, contrasted with the shrinking 21st century version of it. (Dominic Buettner for The New York Times) 5

7 Work has to be done both on the supply as well as the demand side of the energy spectrum Source: SEI, EPSSU 7

8 There is hope! Conveniently electricity can be generated from various sources of motion (already invented in Maynooth, IRL) (particle motion in waves) 8

10 Agenda Changing climate and changing energy mix.... the wave energy resource that is out there!.. different roads lead to Rome.. one company that is going to get it!.. with the right technology.. with the right strategy 10

11 The current and future global demand for vast resources of renewable energy is unquestionable... Source: SAR imagery. Global mean significant wave height (metres) in January... and ocean wave energy forms an immense and yet un tapped resource of renewable energy... 11

12 Both nations and companies have set ambitious targets to harvest the immense wave energy resource Estimated accessible global wave energy resource: 2000 TWh per year 650bn in technology sales Equivalent to global nuclear or hydroelectric generation Source: World Energy Council, 2007 Targets (installed WEC capacity) by 2020: 500 MWe 1.75bn in sales 1360 MWe 4.76bn in sales 1500 MWe 5.25bn in sales 500 Mwe 1.75bn in sales 550 Mwe 1.85bn in sales 12

13 Agenda Changing climate and changing energy mix.... the wave energy resource that is out there!.. different roads lead to Rome.. one company that is going to get it!.. with the right technology.. with the right strategy 13

14 Market opportunities drive innovation Patents in wave energy technology Oil price 14

15 Countless initiatives entered the wave energy arena, but only a handful entered a pre commercial phase 15

16 Out of many varieties, the self reacting point absorber emerges as the most promising wave energy converter The innovation funnel Offshore deep water Floating, self reacting Oscillating system Accessible 25+ years lifetime Survivability Tuneable Large installed power Scale: arrays Smart fabrication Health and safety Wavebob 16

24 Key components of a Wavebob are torus, float, tank, neck and power take off Power Take off Torus Tank Mooring Power control and grid 24

25 Elements of wave theory and hydromechanics (1) Harmonic wave definitions Trajectories of water particles in a deep water wave Superposition of hydro mechanical and wave loads Floating body amplitude response transfer function Source: J.M.J. Journée and W.W. Massie, Introduction in offshore hydromechanics (OT3600), TU Delft,

26 Elements of wave theory and hydromechanics (2) Water particles in waves make circular trajectories 26

27 Elements of wave theory and hydromechanics (3) Irregular waves are a superposition of numerous regular harmonic waves Floating bodies (like the float and torus of a Wavebob) acts as a transfer function of a wave spectrum into an amplitude responses Source: J.M.J. Journée and W.W. Massie, Introduction in offshore hydromechanics (OT3600), TU Delft,

28 Difference in response of torus and float to a certain wave period results in relative motion and a PTO stroke Wave elevation Motion of float 0 20 Motion of torus Piston stroke Time 34 [s]

29 Power, calculated with piston force and velocity (derived from stroke motion) is in phase with the wave Wave elevation Piston force Piston velocity Power Take off Time [s] 29

30 With optimum damping, the power take off combines torus and float motions into a one peak response (RAO) [NOTE: RAO=1 > no relative motion > de tune for safe mode during storm conditions] Torus Float WITHOUT virtual mass 5.00 Torus Float WITH virtual mass Combined damped response RAO (heave/wave) Wave period (seconds) RAO (heave/wave) RAO (heave/wave) Torus Float WITH virtual mass Wave period (seconds) Wave period (seconds) This power capture is then characterised by high loads over a small stroke, and a small relative motion between the float and torus.

31 From the circular motion within a wave, Wavebob captures the power contained in heave direction (example wave period of 15 seconds) CONTROLLING THE MOTION Force OBJECTIVE Circular motion in a wave Vertical motion in PTO Velocity Power take off 31

32 The Wavebob offers unique features like adjustable bandwidth and excellent energy absorption capability De tune for survival Tune to wave climate Tune for maximum power absorption Safe, effective, efficient.

33 Adjustability of PTO damping and tank mass allow Wavebob to extract a large % of available wave power Theoretical maximum wave power Power response Power response to different damping and tank masses Wave period 33

40 Differentiating innovations and systematic engineering minimize cost whilst maximizing generated power Cost / kwh = Cost of (capital + operations + maintenance) Electrical power output 40 40

41 A systems engineering approach is used to capture the complexity of the development process Complexity Transport Deployment Systems Engineering Framework 41

42 Although pragmatic work has been done on transport and deployment procedures for scaled Wavebobs carefully engineered deployment methods of arrays of full scale Wavebobs will vastly reduce OPEX. 42

43 Wavebob is committed to building an integrated system based on three fundamental planning exercises What we will do How we will do it How we will make money Validation of target markets Program Management Plan Economic Models Validation of engineering requirements Validation of cost targets 1. 1 st step in engineering process ahead of detailed design and specification 2. Captures current body of knowledge as it applies to commercial system goals 3. Validated with 3 rd party review and engagement with key stakeholders G u i d i n g p r i n c i p l e s 1. Integrates activities in three areas: Technology development System development/demo Operation & Support planning 2. Uses 2 Phase approach for System Development to allow technology transfers, if ready Identifies target markets by location and application 2. Accounts for industry supports and incentives in near term 3. Determines engineering cost targets as a design requirement
