1 Resonant Wave Power Introduction August 2015 Patrik Möller, CEO CorPower Ocean corpowerocean.com High Efficiency Wave Power page 1

2 Why wave power? The opportunity Significant untapped resource of clean energy High power density Good predictability Different timing compared to Wind and Solar 10-20% of global electricity generation CorPower Ocean High Efficiency Wave Power page 2

3 The challenge Survive without being too large and costly CorPower Ocean High Efficiency Wave Power page 3

4 State of the art: MWh / ton A. Babarit, J. Hals Numerical benchmarking study of a selection of Wave Energy Converters. CorPower Ocean High Efficiency Wave Power page 4

5 Challenges in converting ocean waves to electrons 1. Low velocity motion (typically <0,5m/s) 2. Reciprocating motion 3. Irregular wave periods (6-14s) 4. High loads in extreme waves 5. Highly varying instantaneous power (20:1) CorPower Ocean High Efficiency Wave Power page 5

6 CorPower s Wave Energy Converter Mass production of small compact units drives down cost. Low inertia, effective phase control high capacity factor. Distributed energy Pneu-mechanical production with many small units, giving fault tolerant and predictable output to grid. Phase control 5 x energy density Efficient support and maintenance scheme. Quick and simple install/de-install with standard vessels, enabling low maintenance cost. Relatively low investment cost per unit, lowering entry barriers. (cost of evaluation / capacity expansion of farms). Small & light devices drive train (PTO) Energy density (power per m3 and kg) multiple times higher than competing wave power devices. * (5-30x) Total cost per kw targeted to be commercially viable on the global energy market, without subsidising.* (2-5x) Effective install * Design, calculations and assumptions behind the exceptionally high energy density and low cost per kw being and O&M audited in verification projects involving KTH expertise and external engineering firms during Q2-Q CorPower Ocean High Efficiency Wave Power page 6
