1. 1 | Program Name or Ancillary Texteere.energy.gov Water Power Peer Review Modular Wave Energy Transfer (WET) Jane Vvedensky Shift Power Solutions JaneVvedensky@ShiftPowerSolutions.com November 2011

2. 2 | Wind and Water Power Programeere.energy.gov Purpose, Objectives, & Integration The Challenge: A renewable energy source that is persistent and consistent, with low operating cost, low environmental impact and rapid commercialization. This promotes the Program by: Producing continuous power from wave energy Providing a model product demonstrating a successful renewable Developing methods for rapidly commercializing new power technology Having a cost-effective system to replace or augment legacy systems Our Objective: develop & validate a generation system that Harvests energy from shoreline waves – especially if they are destructive Can be brought to market quickly Can be integrated with grids, legacy systems, renewable sources and storage facilities – or used in isolation Works in variety of conditions & has a low energy cost when mass produced

3. 3 | Wind and Water Power Programeere.energy.gov Technical Approach & Issues Our solution: a modular approach Many small repeating modules = lower manufacturing costs Not just one unit = mitigated points of failure Can be arranged in configurable sets and arrays = customize to site conditions Plug and play components = rapid changeover for maintenance, expansion or upgrade Maintenance by module swap-out = shutdown of entire system not required Designed for near-shore installations or man-made structures  Potential installation siting and permitting obstacles reduced  Can be used to reduce wave impact on structures  Lower costs of installation, operation and maintenance since not in deep open water Solar Panel analogy: direct feed to local loads or combined for utilities Issues : Survivability How to reduce Cost of Energy Improve manufacturing techniques, materials and processes

4. 4 | Wind and Water Power Programeere.energy.gov Unique Features & Accomplishments Unique because: Fast to market - first prototype at full scale Wide market - applicable to both small and large installations Organic-growth business model - steady, secure growth of experience & finance Accomplishments Invented a new generator design Dramatic cost reduction to current design Potentially more effective in converting energy to electricity Amended the initial design: Harvest both heave & surge More robust and survivable for marine environments Built and tested three generator iterations Improved initial design to quadruple output Lab tests extrapolated to known water conditions: 200-400 watts Redesigned manufacturing process Exploring significant cost-savings On budget on target

5. 5 | Wind and Water Power Programeere.energy.gov Plan, Schedule & Budget Schedule Budget: Variance: Scripps wave channel smaller, less expensive Savings to be used for additional testing Expenditure: $337,383. 86% of overall budget.
